Introduction and Technical Specifications

Corsair expanded from a known presence in the memory space to well-respected entity in the component market, offering everything from cases to all-in-one water coolers. Their newest cooler, the Hydro Series™ H75 Liquid CPU Cooler, features a 120mm x 25mm radiator with dual fans and a copper-based water block. The H75 unit includes mounting support for all current Intel and AMD processor offerings. To gage the performance of the cooler, we set it against several other high-performance liquid and air-based coolers. With a retail MSRP of $84.99, the Hydro Series™ H75 cooler is priced to be competitive.

The Hydro Series™ H75 cooler was designed to be a "one size fits all" type cooler, having no space issues fitting in most cases including some of the larger mITX style cases. Corsair used Asetek as an OEM to assist in manufacturing the H75 and appears to be based on the Asetek 550LC all-in-one cooler. As we've seen previously with Corsair OEM products, Corsair had a hand in tweaking the cooler design to meet their performance and aesthetic expectations. The radiator in an all aluminum, thin-finned unit designed to effectively dissipate heat from the liquid medium using the two include Corsair-branded fans.

The water block is composed of a two part acrylic top piece, housing the unit's electronics and pump, held to a copper cold plate secured with an inner and outer ring of screws. The inner ring of screws are counter-sunk to prevent mating-related obstruction and was polished to a mirror-like luster.

Tagged: corsair, cherry, Cherry MX, mechanical keyboard
A lot of diverse topics arose from the Corsair blogs, lately. This time, they compiled fan questions and enlisted mechanical switch and keyboard manufacturer, Cherry Corporation, to provide answers. Coming in at over two-thousand words, it is quite lengthy.
Many of the questions seemed to come from long-term fans of their mechanical keyboards. One person asked whether a specific ergonomic keyboard (G80-5000) would make a return, while another inquired about Cherry-branded Hall Effect switches (presumably for analog controls). In all, if you are interested in mechanical keyboards, it is worth a read. They kept a little secret sauce, secret, but otherwise seemed pretty open in their responses.

Bjorn3D looks at some new members to Corsair's Vengeance family including a mouse, mechanical keyboard and the 1400 Gaming Headset. This headset is refreshingly plain considering the bright colours most of the competition is currently using on their headsets. The 50mm drivers imply decent bass response but unfortunately that was not the experience that Bjorn3D had with this headset, though overall sound was pleasantly clear. For the $80 asking price you get what you would expect, decent headphones with little in the way of accessories or extras but perfect for gamers on a budget.
"Today we have a chance to look at a full gaming gear set from the team at Digital storm which is now a partner with Corsair, so the gear you see here today are all available as accessories to the high-end systems offerings from the team at Digital Storm. This package consists of the Corsair Vengeance M65 Gaming Mouse, the Corsair Vengeance K70 Mechanical Gaming Keyboard and the Corsair Vengeance 1400 Gaming Headset."

Tagged: corsair, mining
When mining some form of cryptographic coin, very few components in the system are utilized. A GPU is basically a self-contained massively parallel cruncher with its own memory and logic. The host system just needs to batch the tasks which leads to PCs with dirt-cheap CPUs, a very modest amount of RAM, and quite literally a half-dozen high-end graphics cards.
If you thought that gaming machines skew a little too much towards GPUs, you should see a mining rig with five R9 290X cards fed by a Sempron.
As you can guess, since many GPUs are double-slot, it might be difficult to fit seven of them in a seven-slot motherboard with a limited number PCIe lanes. To get around this limitation, miners attach their graphics cards to extension cables. Thankfully (for them), mining does not pass a lot of data across the bus to the host system. Even a single PCIe fails to be a bottleneck, apparently.
Anyway, the Corsair blog created an open-air rack which hangs six graphics cards (five HD 7970s and a R9 290X) above a motherboard housing an Intel Celeron G1830. For air, a quartet of Corsair fans suck air upwards and around the graphics cards. For power, of course they use the Corsair AX1500i because why not mine with an arc welding torch. It apparently had more power capacity than the breaker they originally hooked it up to. Whoops.
While ridiculous, I do hope to see systems with multiple (even mismatched) graphics processors as we move toward batches of general mathematics. PhysX was not entirely successful in teaching users that GPUs do not need to be in SLi or Crossfire configurations to load balance. It is just finding an appropriate way to split tasks without requiring a lot of bottlenecks in setting it up.
I might not mine coins, but I could see some benefit to having 35 TeraFLOPs across seven compute devices. I could also see Corsair wanting to sell me a power supply for said PC.
The Mini ITX Surge Continues
For years now the enthusiast crowd has been clamoring for Corsair to bring its case building prowess down to the Mini ITX market and with the Obsidian 250D it has done just that. By combining the design features that have make Corsair's units so popular with the aesthetic touches of the most recent Obsidian lineup, the 250D is an interesting and combination of size and performance.
The Corsair 250D is unlike most other Mini ITX designs out today in that it supports a lot of full size components. You'll be able to use a standard ATX power supply, many self contained water coolers, full size graphics card and won't have to suffer through the most painful cable routing aspects of other small form factor cases.

Tagged: ssd, hdd, corsair
The Corsair Blog has been publishing several really interesting articles, lately. In January, they wrote an editorial which quantifies the benefits of modestly overclocking CPU, GPU, RAM, and all of the above. Their benchmarks showed which tests favored what type of component.
This time, they look at the benefits of SSDs. Their Neutron Series GTX 240GB SSD was compared against a 3TB WD Black HDD (which is decent drive). To get into the campaign, they measured an SSD requiring a little over two minutes while the HDD took a little over two-and-a-half minutes. Multiplayer was much more significant: an SSD made it in game in 42 seconds while the hard drive took 69 second. That is a whole 40% faster.
Most importantly, getting into the game a whole 27 seconds earlier gives you first pick at vehicles. The game keeps them briefly locked to allow users to connect but, as is usual for Battlefield games, there is still an advantage for people with fast hard drives. Battlefield 2 was the unspoken benefit of purchasing a Western Digital 10,000 RPM Raptor drive, way back in 2006. You joined in as soon as you loaded which could mean nearly half of a minute to get your vehicle and go.
Shhh. Don't tell anyone.
Introduction and Features
Corsair's new CS Series Modular PSUs include four models; the CS450M, CS550M, CS650M and CS750M. All of the power supplies in the CS Series feature modular cables, high efficiency (80 Plus Gold certified) and quiet operation. In addition, Corsair continues to offer a full line of high quality power supplies, memory components, cases, cooling components, SSDs and accessories for the PC market.
Here is what Corsair has to say about their CS Series Modular PSUs: “The CS Modular Series is designed for basic and midrange PCs, but offers features and performance traditionally reserved for higher-end models. 80 Plus Gold efficiency and a thermally controlled fan ensure quiet operation and lower energy use, and the modular, detachable cable set makes installations and upgrades faster and better looking.”
“80 Plus Gold rated efficiency saves you money on your power bill and produces less heat than less efficient power supplies. The flat black modular cables allow you to enjoy fast, neat builds. And, like all Corsair power supplies, CS Series Modular is built with high-quality components and is guaranteed to deliver clean, stable, continuous power.”

Tagged: corsair, overclocking
I rarely overclock anything and this is for three main reasons. The first is that I have had an unreasonably bad time with computer parts failing on their own. I did not want to tempt fate. The second was that I focused on optimizing the operating system and its running services. This was mostly important during the Windows 98, Windows XP, and Windows Vista eras. The third is that I did not find overclocking valuable enough for the performance you regained.
A game that is too hefty to run is probably not an overclock away from working.
Thankfully this never took off...
Today, overclocking is easier and safer than ever with parts that basically do it automatically and back off, on their own, if thermals are too aggressive. Several components are also much less locked down than they have been. (Has anyone, to this day, hacked the locked Barton cores?) It should not be too hard to find a SKU which encourages the enthusiast to tweak some knobs.
But how much of an increase will you see? Corsair has been blogging about using their components (along with an Intel processor, Gigabyte motherboard, and eVGA graphics card because they obviously do not make those) to overclock. The cool part is they break down performance gains in terms of raising the frequencies for just the CPU, just the GPU, just the RAM, or all of the above together. This breakdown shows how each of the three categories contribute to the whole. While none of the overclocks are dramatic, Corsair is probably proud of the 5% jump in Cinebench OpenGL performance just by overclocking the RAM from 1600 MHz to 1866 MHz without touching the CPU or GPU.
It is definitely worth a look.
The stars are aligned
One of the most frequent questions we get at PC Perspective is some derivative of "is now the time to buy or should I wait?" If you listen to the PC Perspective Podcast or This Week in Computer Hardware you'll know that I usually err on the side of purchasing now. Why should you hold yourself back on the enjoyment of technology unless something DRAMATIC is just over the horizon.
This week I got another such email that prompted me to do some thinking. After just returning from CES 2014 in Las Vegas, I think its fair to say that we didn't hear anything concrete about upcoming SSD plans that would really be considered monumental. Sure, we saw plenty of PCIe SSDs as well as some M.2 options, but little for PC enthusiasts or even users that are looking to replace the hard drives in their PlayStation 4. Our team thinks that now is about as good of a time to buy an SSD as you will get.
And while you are always going to see price drops on commodity goods like flash storage, the prices on some of our favorite SSDs are at a low that we haven't witnessed without the rebates and flash deals of Black Friday / Cyber Monday. Let's take a look at a few:
Note: It should go without saying that all of these price discussions are as of this writing and could change...
Samsung 840 EVO 1TB SSD (Red: Amazon, Yellow: Newegg) - Graph courtesy HoverHound
The flagship SSD from the Samsung 840 EVO series SSDs, also the personal favorite of Allyn and most of the rest of the PC Perspective team, is near its all-time low in price at just $529 for a 1TB capacity. That is a cost per GB of just $0.529; no rebates, no gimmicks.
Samsung 840 EVO 500GB SSD (Red: Amazon, Yellow: Newegg) - Graph courtesy HoverHound
Likely the most popularly purchased of the EVO series is the 500GB model that is currently selling on Amazon for $309, or $0.618/GB. Obviously that is a higher mark than the 1TB hits but as you'll see in our tables below, in general, the higher capacity you purchase at the better value per GB you are going to find.
There are other capacities of the Samsung 840 EVO starting at 120GB, going to 250GB, and even a 750GB, all are included in the pricing table below. Depending on your budget and your need for the best perceived value, you can make a decision on your own.
Let's not forget the other options on the market; Samsung may be the strongest player today but companies like Intel, OCZ and Corsair continue to have a strong presence. The second best selling series of SSD during the holidays was the Intel 530 series of drives that utilize the LSI SandForce SF2281 controller. How do they stack up price-wise?

Tagged: graphite series, full tower, corsair, CES 2014, CES
In addition to the Mini-ITX Obsidian 250D, Corsair is launching two full tower gaming cases under its Graphite series. The Graphite 760T and 730T are full tower cases constructed of steel and aluminum that incorporate many enthusiast-friendly features. The 760T and 730T share the same form factor and general design including two hinged side panels, tool-less drive bays, and support for air and water cooling options. Note that the 730T has metal side panels while the 760T has two windowed side panels and adds a fan controller. Further, the 760T comes in two color options (black and arctic white) while the 730T is only available in black.
The pair of full tower cases join the existing mid-tower 230T in the Graphite Series. The 760T and 730T are large 22.4" x 9.7" x 22.2" cases that offer up lots of cooling, expansion, storage, cable management, and motherboard support options. The case has a large mesh front panel that has two LED-lit AF140L 140mm fans and three 5.25" drive bays. On the top edge of the case is the front IO panel which includes two USB 3.0 ports, two USB 2.0 ports, two audio jacks, and power and reset buttons. The two side panels are hinged at the back and open using a handle at the front. The left side panel is transparent to show off your hardware while the opposite side panel is opaque. In all, the Graphite 760T and 730T are attractive cases with straight lines and roughly octagonal shape. The case is lifted above the ground using large case feet.
Internally, the case supports 9 PCI slots, three 5.25" drive bays, six 3.5" (or 2.5") hard drives in two modular (and removable) drive cages, four side-mounted 2.5" SSDs, seven cooling fans, ATX motherboards, and ATX power supplies. Users should have no problem fitting a beefy multi-GPU setup into the new Graphite cases.
When it comes to cooling, the Graphite 760T and 730T support up to seven fans. Corsair includes two LED-lit AF140L 140mm fans in the front and a single AF140L fan in the rear that come pre-installed. From there users can add three 140mm or 120mm fans to the top and a single 120mm fan to the bottom of the case. Users that opt for water cooling can instead install a 360mm radiator in the top of the case and a 280mm radiator to the bottom of the case. The 760T includes a fan speed switch that switches between 12V and 7V power to control the speed (and noise) of the cooling fans. The cheaper 730T does not include this integrated fan controller, however.
Both the 760T and 730T will be available in February from Corsair's authorized distributors and will include a 2 year warranty. The Graphite 760T has an MSRP of $179.99 for the black version and $189.99 for the arctic white SKU. On the other hand, if you can live without windowed side panels, a fan controller, and only one color choice, the black Graphite 730T has an MSRP of $139.99.
Personally, I find it to be a neat looking case that I am considering for my next build assuming the reviews hold up on the build quality. What do you think about the newest entrants to Corsair's Graphite Series?
