Yadda yadda arc welding yadda Allyn yadda yadda podcast bingo.

For the last seven or eight years, Corsair has released a boatload of power supplies, running the whole gamut of potential customers, since their initial HX620W release in 2006. Their current line-up is broken into eight distinct series. Some are modular, some are fully modular, and others are not. Several models hold the lowercase "i" suffix which signify USB connectivity to monitor and adjust the unit from their Corsair Link utility.

Today, Corsair is announcing the AX1500i fully modular power supply. At 1500 watts, this should be an effective upper limit on desktop power consumption. The real news is its efficiency: 94% efficient at half load on 115V input (North America). The PSU exceeds the specification set out for 80 PLUS Platinum and falls within the current draft of 80 PLUS Titanium (consumer).

It is also designed to be quiet and even fanless when drawing under 450 watts.

The suffix on the AX1500i signifies that it also integrates with Corsair Link through USB. Temperature, draw, loads, fan speed adjustments, and power efficiency are exposed to the user who wants to see a few more graphs in their secondary monitors... because if you have a single 1080p panel then you are doing something wrong somewhere.

The AX1500i is expected to retail for $449.99 in Q2 2014 and is backed by a 7-year warranty.

CES 2014: Corsair Raptor K40 RGB LED & Raptor M45

Subject: General Tech, Cases and Cooling, Shows and Expos | January 7, 2014 - 09:00 AM |
Tagged: membrane keyboards, corsair, CES 2014, CES

The headline is, "Corsair Unleashes Raptors in Las Vegas". We do not have any footage of the disaster so, in its place, we will post stock footage of a similar calamity in Chicago from over three years ago.

Thank you, Team Coco.

So many dead bees. They... only sting once.

Actually, the Raptors at CES are keyboards (with RGB LED backlighting) and mice. This line is a step below their mechanical offerings so these do not include the newly announced Cherry MX RGB switches. The Corsair K40 is based on typical membrane switches but, unlike the vast majority of keyboards based on that cheaper technology, is said to be "full-key rollover on USB". This typically means that each key is unique (rather than grouped into a matrix) and the USB limitations are circumvented by registering as multiple keyboards.

corsair-K40_US_B_RED.png

This keyboard is advertised as "anti-ghosting" although, like NKRO keyboards, it does not block ghost inputs... it simply cannot ghost in the first place. Ghosting occurs when the user presses three (or more) specific keys which sends the same signal as maybe a half dozen other keys on the same segment of the matrix. If each segment is basically a single key? No problem can exist. Higher-end keyboard manufacturers advertise anti-ghosting because it is a marketing term despite actually being above the problem in its entirety.

The M45 optical gaming mouse is 5000 DPI and has 7 programmable buttons.

The Raptor K40 gaming keyboard will be available this month for $79.99. The Raptor M45 will also be available in January for a list price of $59.99. Both products have a two year manufacturer warranty.

The Hydro Series ™ H105 Liquid CPU Cooler features a dual-fan radiator capable of hosting up to four 120mm fans (two on the front and two on the back). The radiator has been redesigned compared with past models to enhance its cooling potential. Corsair increased the radiator thickness to 38mm (compared to the 25mm thickness on the H100), increasing the radiator's surface area for better heat dissipation potential compared with the 25mm models. Further, Corsair redesigned the CPU mounting block to make it entirely tool-free. The CPU block is a round copper base plate with an integrated pump and illuminated Corsair logo.

CES 2014: Corsair Launches the Obsidian 250D Mini ITX Case

Subject: General Tech, Cases and Cooling | January 7, 2014 - 09:00 AM |
Tagged: obsidian 250d, corsair, CES 2014, CES

Do you like the design of Corsair's Obsidian Series PC cases, but don't have room for a mid-tower or full tower form factor? Well, Corsair may have a solution for you with the release of its new Obsidian 250D, which is the company's first Mini ITX chassis. The Obsidian 250D brings the aesthetics and many of the builder-friendly features of its larger brethren in a small sub-$100 brushed aluminum and steel case.

Specifically, the Obsidian 250D measures 11.4" x 10.9" x 13.81". The cube-like case is all black with a basic brushed aluminum texture. Corsair branding, a single 5.25" drive bay, two USB 3.0 ports, and two audio jacks adorn the front while vents sit on the left, right, and rear sides of the case. Further, the top panel of the case is removable and is how you get to the internal hardware. The case is propped up on integrated feet as well.

250D_hero_down_from_left.png

Corsair's new Mini ITX case supports both air and water cooling. The case comes pre-installed with one AF140L and one AF120L fan, and users can install a total of 5 fans (including the bundled fans). On the water cooling front, users can install a 120mm or 140mm radiator in the front of the case as well as a 120mm or 240mm radiator on the side of the case. One nice feature on the cooling front is that Corsair has included removable dust filters on the front, side, and PSU vents.

250D_Close_up_hydro_series_install.png

Despite the Mini ITX form factor, the case actually allows users to cram a fair amount of hardware into it. In all, the Obsidian Series 250D supports two PCI slots, four hard drives, a single optical drive, a full size power supply, and Mini ITX motherboards. Users can install a graphics card up to 290mm in length, which is most cards on the market at a bit over 11-inches. The case supports ATX power supplies up to 200mm. When it comes to storage options, users can install up to two 2.5" drives and two 3.5" drives (or four total 2.5" drives) which is not bad. Additionally, this Obsidian case features cable management tie down points and tool-less drive bays.

250D_back_view.png

The Obsidian 250D has an MSRP of $89.99 and will be available for purchase later this month in the US. The mini ITX chassis comes with a 2 year manufacturer warranty. It looks like a decent case, and I'm interested to see what reviewers have to say about it when it comes to ease of working with and installing hardware into.

CES 2014: Corsair Unveils Cherry MX RGB Keyboard

Subject: General Tech, Cases and Cooling, Shows and Expos | January 6, 2014 - 07:00 PM |
Tagged: CES 2014, CES

While most of the information has already been discussed, Corsair and Cherry have now officially debut their first MX RGB keyboard. These special switches allow for 16.8 million colors to be selected for any individual key. Corsair provided us with a video of several effects in action from a wavy rainbow to shock waves emanating from specific points - even more practical configurations such as alternate colors for the WSAD and the arrow keys.

Keyboards containing three of the four main switches (Red, Blue, and Brown) will be available in the second half of this year. There is the curious omission of the Black switches, essentially Reds with a tougher spring, but I was honestly not expecting anything but the Reds.

The initiative is called the "MX RGB Project" (which is a suitable name albeit a little bland). The models shown at CES are based upon the Vengeance K70. There is currently no word, yet, about which models will be presented at launch later in the year.

The main point of this announcement, however, is to note that the keyboards will be on display from now until the evening of January 9th.

Tagged: water cooling, ROG, nvidia, gtx 780, gtx 770, CES 2014, CES, asus

In keeping with their tradition of pushing the innovation and performance boundaries through their ROG product line, ASUS today released NVIDIA-based 7-seried video cards featuring as part of their Poseidon series of liquid cooled products. ASUS released both a GTX 780 and GTX 770-based product with the hybrid Poseidon cooling solution.

All Poseidon series graphics cards come with a hybrid cooling solution, using a combination of fan-based and water-based cooling to propel these cards to new performance heights. The card's GPU is cooled with the DirectCU H20 cooler with water pathed through the integrated barbs to the copper-based cooler. The water inlets are threaded, accepting G1/4" sized male fittings. The memory and VRM components are cooled by a massive dual-fan heat pipe, exhausting air through the rear panel port. Both cards feature the red and black ROG coloration with the Poseidon series name displayed prominently along the right front edge of the card.

Both Poseidon series graphics cards, the ROG Poseidon GTX 770 and ROG Poseidon GTX 780, include ASUS' DIGI+ VRM and Super Allow Power power circuitry to ensure stability and component life under the most grueling conditions. When paired with the Poseidon cooling, the GPU ran 20% cooler and 3 times quieter than a comparable reference card with card operating temperatures 16 C lower than the same reference solution.

Sharkoon's big bad Bulldozer enclosure

Tagged: sharkoon, bulldozer

If subtle just isn't your thing then the Sharkoon Bulldozer might be a good case for you.  At 480 x 235 x 460mm (18.9 x 9.2 x 18.1") this is a large case and the numerous LED lights will make this case stand out even more, not to mention the unique paint job on the interior.  There are 10 drive bays which can be modified for 3.5" or 2.5" drives with one bay removable to give your GPU some extra space.  eTeknix liked the bottom mounted PSU and cable runs which make for a clean looking system but you will really have to like the exterior look if you consider buying this case.

"Sharkoon are not what I would call most people’s first choice when it comes to picking a new chassis, at least not here in the UK. However, we’ve seen a couple of Sharkoon products in the eTeknix office over the last couple of years that really impressed us, not only for being great cases, but also because they offered great value for money. This has left us eager to see more from Sharkoon and today we will be taking a look at their new Bulldozer chassis, a budget friendly ATX chassis that is available in a choice of three colours. Blue, Green or Red LED edition are available, with the blue model coming in a grey chassis, while the green and red LED models come in a black chassis."

Valve Releases Steamworks API for Steam Controller

Subject: General Tech, Cases and Cooling | December 19, 2013 - 12:42 AM |
Tagged: valve, Steam Controller

The Steam Controller is a gamepad where touch replaces analog joysticks. Developed internally at Valve, its design focused on being a comfortable gaming accessory which did not compromise on the accuracy allowed by an absolute position-based input device (ie: a mouse). Velocity-based inputs, such as thumbsticks, have the hand-eye and/or timing problem where we need feedback to know when to cease giving input to actually stop. It is a lot easier to make a good estimate of how far to move your hand (or finger, or eye) and perform that action without further feedback necessary.

It is just how we behave.

steam-controller_bindings.jpg

Valve is very confident in their design and believes that it is accurate enough to emulate a mouse. In fact, most games (if and until the Steam Controller gains traction) will be operating in "Legacy Mode" which emulates a mouse and keyboard. They are requesting that the community develop many shared profiles, on a game-by-game basis, to give a large catalog of known configurations by the time the device ships publicly.

But what about the not "Legacy Mode"? The main announcement is that Valve has shipped the controller's Steamworks API to allow developers direct access to its hardware. In other words, rather than emulate a mouse and keyboard, the developer can use the hardware in the way they see fit. Of course this will be most useful for the touchscreen (if a blank 4-quadrant button is insufficient) and the haptic feedback but can also mean new methods of emulating the velocity-based input of a gamepad.

Remember, I said velocity input is less accurate for things like rapid rotation between randomly oriented targets. Flight games often prefer long continuous input which are great for joysticks and thumbsticks. Simply put, traditional gamepads are "better" at certain things (driving games, flight games, third-person games where accuracy is not important but quickly pressing one of four-or-so commands is, etc.). Many developers will want this controller to solve those problems, too.

Keep an eye out at Steam Universe for more updates like these; they occur rapidly as of late.

PC Power & Cooling have been providers of high quality PSUs for a long time and are keeping up the pace, recently with the updated 750W Silencer Mk III.  They have a unique style, black and white colouring and a proprietary connector for their modular cabling that both looks and connects better than some of the recessed plastic connectors seen on other models.  Unfortunately since OCZ purchased the company they have gone from being the PSU all other companies try to match to a mid-range supplier that provides decent PSUs but lack the incredible quality they once possessed, as you can see by [H]ard|OCP's Pass marking without an award.  This may well be one of the last models you see labelled PC Power & Cooling, with OCZ's bankruptcy the continuation of the PSU business is in doubt.

NZXT G10 Allows Users To Unleash The AIO Water Cooler Kraken On Graphics Cards

Subject: Cases and Cooling | December 12, 2013 - 01:03 AM |
Tagged: water cooling, nzxt, kraken, gpu cooler

NZXT has a new cooling product coming out next week that caught my attention recently. Called the KRAKEN G10, it is a bracket and fan assembly that allows users to attach All In One (AIO) water coolers – those traditionally aimed at CPUs – to graphics cards. The Kraken G10 consists of a steel bracket with a CPU waterblock mounting hole, 92mm fan, and water tube routing space.

Red Kraken G10 AIO Water Cooler Bracket.jpg

The Kraken G10 is a stylish approach to pairing cheap sealed water coolers to graphics cards with reference PCBs – a feat that has traditionally been limited to adventurous enthusiasts armed with zip ties and a good deal of patience. The bracket is compatible with many recent GPUs from both AMD and NVIDIA, and it allows enthusiasts to mount AIO water coolers from NZXT as well as other manufacturers. The water cooler is then able to efficiently cool the GPU while the pre-installed 92mm fan works to keep the VRM and memory areas of the graphics card cool. The G10 bracket measures 177 x 32.5 x 110.6 mm (WxHxD) and comes in white, black, or red with white fan blades and NZXT logos on the side and fan.

NZXT KRAKEN G10 GPU Bracket With Fan.jpg

Specifically, the KRAKEN G10 supports the following graphics card models (with reference PCBs only).

AMD NVIDIA
  • R9 290X
  • R9 270X
  • HD 7870
  • HD 7850
  • HD 6970
  • HD 6950
  • HD 6870
  • HD 6850
  • HD 6790
  • HD 6770
  • HD 5870
  • HD 5850
  • HD 5830
  • GTX TITAN
  • GTX 780
  • GTX 770
  • GTX 760
  • GTX 680
  • GTX 670
  • GTX 660 Ti
  • GTX 580
  • GTX 570
  • GTX 560 Ti
  • GTX 560
  • GTX 560SE

Further, users can use the G10 to mount the waterblocks of the following sealed loop water coolers.

Antec Corsair NZXT Thermaltake Zalman
KUHLER H2O 920V4 H110 KRAKEN X60 Water 3.0 Extreme LQ-320
KUHLER H2O 620V4 H90 KRAKEN X40 Water 3.0 Pro LQ-315
KUHLER H2O 920 H55   Water 3.0 Performer LQ-310
KUHLER H2O 620 H50   Water 2.0 Extreme  
      Water 2.0 Pro  
      Water 2.0 Performer  

It is a niche, but useful, product that can allow users to more easily upgrade the cooling of their graphics cards to allow for higher overclocks and/or quieter operation. The NZXT KRAKEN G10 will be available on December 16, 2013 for $29.99 from NZXT’s website. Update: It appears the first batch of G10 brackets has sold out already. Fret not, a second batch of Kraken G10s will be available towards the middle of next month according to NZXT. (End of update.)

The three little letters that instill fear in tech journalists (and vendors) right around the holiday season: CES. This will be the first of many news posts coming out of that event -- it is still a month away! Companies are already preparing for what will come after the holidays. Brace yourselves!

januaryiscoming.jpg

Corsair and Cherry have just released a preview of their upcoming CES announcement. Mechanical keyboards (at least those based on Cherry MX switches) were only rarely backlit. Pretty much every model of Cherry MX-based keyboard with per-key LED lighting was, at one point, developed by iOne (they produced the XArmor line of backlit keyboards and collaborated with Razer on the BlackWidow). I am not particularly sure what the difficulty was from an engineering standpoint but I do know it was rare.

cherry-mx-rgb.jpg

Cherry, themselves, are assisting the next evolution of this technology. The company has developed a special version of their MX Red-class switch with built-in RGB illumination. The mixture of these three colors allows for a key to be lit by any color in the visible spectrum (up to the precision allowed by hardware and software). Their press release suggests 8-bit per channel control (~16.7 million colors). Their exclusive launch partner for this 2014 debut will be Corsair.

Clearly their K-series keyboards sold well.

If you want to learn more about the Cherry MX switches, be sure to check out our overview from 2012. Also, check out the Cherry website for a ridiculously informative breakdown of the switch all each of its components. Seriously, this puts my animation to shame; it is kind of depressing.

Noctua puts their new NH-U12S on a diet

Tagged: noctua, NH-U12S, heatsink

Noctua have attempted to strike a balance between performance and profile with the NH-U12S, slimming it down to allow for tall heatspreaders to be used on RAM but without shaving off too much performance.  From the tests performed at [H]ard|OCP it seems that Noctua did exactly what they claimed, there is plenty of space to fill all your DIMM slots with any brand of RAM and the performance at stock speeds was better than average.  It is a little more expensive than some alternatives and is not the best at cooling an overclocked CPU but but of you want a slim profile and reasonably quiet performance this is a good choice.

13829767775PnGPdYKj4_2_7_l.jpg

"The Noctua NH-U12S is well known in enthusiast circles for a few reasons. Noctua states it is because, "the NH-U12S is a complete premium quality solution that combines outstanding performance, quiet operation and excellent compatibility." And quite frankly Noctua would be very correct. Where does the value stand today?"

AMD Releases Catalyst 13.11 Beta 9.2 Driver To Correct Performance Variance Issue of R9 290 Series Graphics Cards

Subject: Graphics Cards, Cases and Cooling | November 7, 2013 - 11:41 PM |
Tagged: R9 290X, powertune, hawaii, graphics drivers, gpu, GCN, catalyst 13.11 beta, amd, 290x

AMD recently launched its 290X graphics card, which is the new high-end single GPU solution using a GCN-based Hawaii architecture. The new GPU is rather large and incorporates an updated version of AMD's PowerTune technology to automatically adjust clockspeeds based on temperature and a maximum fan speed of 40%. Unfortunately, it seems that some 290X cards available at retail exhibited performance characteristics that varied from review units.

Retail versus Review Sample Performance Variance Testing.jpg

AMD has looked into the issue and released the following statement in response to the performance variances (which PC Perspective is looking into as well).

Hello, We've identified that there's variability in fan speeds across AMD R9 290 series boards. This variability in fan speed translates into variability of the cooling capacity of the fan-sink. The flexibility of AMD PowerTune technology enables us to correct this variability in a driver update. This update will normalize the fan RPMs to the correct values.

The correct target RPM values are 2200RPM for the AMD Radeon R9 290X "Quiet mode", and 2650RPM for the R9 290. You can verify these in GPU-Z. If you're working on stories relating to R9 290 series products, please use this driver as it will reduce any variability in fan speeds. This driver will be posted publicly tonight.

From the AMD statement, it seems to be an issue with fan speeds from card to card causing the performance variances. With a GPU that is rated to run at up to 95C, a fan limited to 40% maximum, and dynamic clockspeeds, it is only natural that cards could perform differently, especially if case airflow is not up to par. On the other hand, the specific issue pointed out by other technology review sites (per my understanding, it was initially Tom's Hardware that reported on the retail vs review sample variance) is  an issue where the 40% maximum on certain cards is not actually the RPM target that AMD intended.

AMD intended for the Radeon R9 290X's fan to run at 2200RPM (40%) in Quiet Mode and the fan on the R9 290 (which has a maximum fan speed percentage of 47%) to spin at 2650 RPM in Quiet Mode. However, some cards 40% values are not actually hitting those intended RPMs, which is causing performance differences due to cooling and PowerTune adjusting the clockspeeds accordingly.

Luckily, the issue is being worked on by AMD, and it is reportedly rectified by a driver update. The driver update ensures that the fans are actually spinning at the intended speed when set to the 40% (R9 290X) or 47% (R9 290) values in Catalyst Control Center. The new driver, which includes the fix, is version Catalyst 13.11 Beta 9.2 and is available for download now. 

If you are running a R9 290 or R9 290X in your system, you should consider updating to the latest driver to ensure you are getting the cooling (and as a result gaming) performance you are supposed to be getting.

Catalyst 13.11 Beta 9.2 is available from the AMD website.

Back in the ancient past of aircooling, when heatsinks did not weigh a kilogram and 120mm fans were a novelty item and not the standard many enthusiasts practiced the art of lapping.  With a water tray and automotive grade sandpaper of increasingly fine grit you could not only flatten the base of the heatsink, something that was all too necessary for some models, you could also acheive a mirror finish which helped your heat paste spread evenly.  Today you do not hear much talk of lapping either heatsinks nor the integrated heatspreader on CPUs and SPCR decided to test if it remains a good practice.  Check out the difference a proper lapping job still makes, though keep in mind lapping the IHS on your CPU will void the warranty and could weaken its structure.

"Lapping the CPU in a heatsink test platform is probably a controversial move that's bound to provoke reactions. Funny thing is, it was done a year ago, and photos of the CPU showing the copper top exposed by the lapping have been featured in many of our reviews. Yet, not a single comment. This article goes through the problems, investigations and explorations that led us to lap our Core i7-965 Extreme test CPU, and analyzes the results and implications."

Price, performance and efficiency from be quiet!, the Pure Power L8 700W

Subject: Cases and Cooling | October 29, 2013 - 02:23 PM |
Tagged: PSU, be quiet!, Pure Power L8, 700W, 80 Plus Bronze

Be Quiet! could have a value-priced winner with their Pure Power L8 700W PSU, which has enough power to handle SLI/CrossFire but with a non-modular design which should keep the price fairly reasonable.  With two 12V lines capable of providing up to 53 amps you will be able to run two powerful GPUs, though perhaps not paired flagship cards.  As far as efficiency goes, Legit Reviews found it to deserve the 80 Plus Bronze rating it carries and the power regulation and ripple were both very good for any PSU, let alone a value priced one.  You can't buy it yet but you can see the review right here.

"Be Quiet! is an European company which, despite the strange name, is a very well-known manufacturer amongst enthusiasts, mostly for their high quality (and notoriously expensive) power supply units. We had an encounter with their very impressive Dark Power Pro 10 series a few months ago; however, impressive as it was, the price tag of such a power supply would certainly drive the vast majority of users away. Today we will be having a look at the least expensive PSU series currently offers, the Pure Power L8."

Hide your CPU under a Dark Rock Pro

Tagged: be quiet!, Dark Rock Pro 2, LGA1150

The be quiet! Dark Rock Pro 2 is an imposing cooler standing 166mm tall, 147mm wide and 138mm deep (6.5x5.8x5.4") and weighing in at 1.25kg which means not all cases can accommodate it and it will dwarf an mATX board.  The two fans are mismatched, one is 135mm and one is 120mm however [H]ard|OCP's testing proved that does not mean it is a loud cooler.  It's cooling ability is quite impressive and puts it at the top of the chart; unfortunately so does its $90 price tag which is higher than other competitive coolers.  If you can find it on sale it is well worth investing in.

"CPU air cooling and huge cooler sizes have become synonymous. One thing that is not synonymous with high end air cooling are muted sound profiles. be quiet! looks to remedy this issue with its Dark Rock Pro 2 CPU air cooler that sports a tremendous 220 watt cooling capacity all in that be quiet! package."

Fremont, California — October 24, 2013 — Corsair, a worldwide designer of high-performance components for the PC hardware market, today announced the Hydro Series H75 dual-fan 120mm liquid CPU cooler. The easy-to-install H75 provides PC users with quieter and more effective cooling than stock CPU coolers, all in a 120mm footprint that is widely compatible with most PC cases on the market. The Hydro Series H75 will be available in November at a suggested retail price of $84.99 (USD).

The Hydro Series H75 is comprised of a low-profile CPU cooling block connected to a 120mm radiator and fan assembly via kink-resistant rubber tubing. The H75’s new cooling block is designed with a micro-fin copper cold plate and a high-quality, ceramic bearing pump that provides reliable, low-noise heat transfer away from the CPU. The slim 25mm thick radiator is surrounded by dual SP120L PWM 120mm fans resulting in design that is quieter and thinner than other dual fan coolers, and more effective at dispersing heat than single fan designs. The H75’s fans work with PWM motherboard fan headers, allowing users to control the fan speed and noise levels from their motherboard’s built-in software or BIOS.

“The H75 is a great choice for PC enthusiasts who want the streamlined features of our H60 120mm cooler but desire the additional cooling performance of a dual fan design,” said Xavier Lauwaert, Director of Product Marketing at Corsair.

The Hydro Series H75 features a simple, tool-free mounting system and wide Intel and AMD socket compatibility. Like all Hydro Series liquid CPU coolers, the H75 is completely self-contained and does not require filling or maintenance.

Seasonic PSUs Will Power HashFast Bitcoin Miners

Subject: General Tech, Cases and Cooling, Systems | October 22, 2013 - 04:10 PM |
Tagged: seasonic, Power Supplies, mining, bitcoin, asic

Seasonic (Sea Sonic Electronics) has announced a design win that will see its power supplies used in HashFast’s bitcoin mining rigs. The upcoming HashFast mining rigs feature the company’s “Golden Nonce” ASIC(s) and all-in-one water coolers. HashFast has a single ASIC Baby Jet and multi-ASIC Sierra rig. Both units will be available December 15 starting at $2,250 and $6,300 respectively.

The Seasonic power supplies are high efficiency models with Japanese capacitors and at least 80 PLUS Bronze. On the high end, Seasonic has PSUs that are up to 93% efficient. HashFast stated that it chose Seasonic for its mining rigs because of the build quality and efficiency. The Baby Jet and Sierra mining rigs allow users to overclock the ASICs, and the systems can be rather demanding on PSUs.

The Golden Nonce ASIC is a 28nm chip that is rated at 400 GHash/s and 0.65 Watts per Gigahash.

Beyond that, the companies have not gone into specifics. It is good news for Seasonic, and should mean a stable system for bitcoin miners (the 93% efficiency rating is nice as well, as it means less wasted electricity and slightly more bitcoin mining profit).

The full press blast is below for reference.
