Seasonic's new X-1250 PSU can provide 1250W of power, just as the name suggests, with up to 104 amps to the 12V rail which should provide enough power for even the most power hungry GPUs.  Instead of going with a single rail design Seasonic chose to provide 4 rails so you should ensure to know which plugs you are using.  It passed all of [H]ard|OCP's torture tests with flying colours, making it one of the better kilowatt ckas PSUs they have had the pleasure of testing and when you consider the price, with or without the rebate, it is a perfect choice for users building a system with multiple GPUs.

"Seasonic makes some of the best enthusiast computer power supplies in the world. It has long produced some of the cleanest power producing PSUs along with being some of the quietest on the market. The new fully modular X-1250 sports many enthusiast features and touts gold level efficiency. Is this new X-1250 worthy?"

Corsair AXi/AX PSU Refresh: AX860, AX860i, AX760, AX760i

Subject: General Tech, Cases and Cooling | November 6, 2012 - 08:00 AM |
Tagged: PSU, corsair, 80 Plus Platinum PSU

It has not been too long since Lee Garbutt reviewed Corsair’s AX1200i Power Supply. Corsair used that product to introduce their Corsair Link Dashboard to the monitoring of Power Supply performance. Lee was very impressed with the supply and gave it a Gold Award.

AX860i_PSU_sideview_a@300.jpg

Some of us are not looking to power a microwave inside our PCs. Corsair has thusly brought that feature to lower wattage PSUs with their new AX860i and AX760i. These PSUs achieve 80 PLUS Platinum certification along with the Digital Signal Processor connection to monitor. If you would rather have $30 USD instead of monitoring capabilities: each model number without the i contains the same 80 PLUS Platinum certification just without the monitoring capabilities. As an added bonus the Corsair power supplies should be very silent. The 860W power supply will shut down its fan to 0 RPM until it reaches a 60% load while the 760W will operate without fans until a 70% load.

These PSUs will be available in November and are priced: $249.99 USD for the AX860i vs. $219.99 USD for the AX860. The AX760i will be available for $229.99 USD vs. $199.99 for the AX760. Again, the i denotes the ability to be monitored by Corsair’s Link Dashboard software.

Press blast after the break!

The second coming of the AX1200, now with software controls

Corsair's new AX1200i PSU is 80 Plus Platinum rated and sports Link monitoring and control software as you might remember from Lee's review.  On the off chance that you would like a second opinion about the PSU, [H]ard|OCP recently published their own review.  Just like Lee they were impressed with the voltage regulation, efficiency, and DC Output quality though they were less impressed with the noise they saw during their Transient Load Test.  They also questioned the use of the Link tweaking software and while the final verdict was positive in some ways they didn't feel this PSU was as true successor to the stellar AX1200 released almost two years ago.

H_Corsair_ax1200i.jpg

"Corsair has a refresh today that talks to its high end line of high power PSUs. The AX1200i comes in touting "platinum" efficiency and "an unprecedented level of monitoring and performance customization." How does the AX1200i perform out-of-the-box and does it actually bring value at its huge price?"

Enermax hits 1350W and gets rated Platinum as well

Subject: Cases and Cooling | September 28, 2012 - 02:30 PM |
Tagged: PSU, modular psu, enermax, 80 Plus Platinum, kilowatt, Platimax 1350W

If the 1500W EVGA SuperNova PSU that Lee recently reviewed was a little too much for you then how about the Platimax 1350W from Enermax?  It sports six 12V rails, two at 20A and the remaining at 30A, a mere eight 6+2 pin PCIe power connectors and 14 SATA power connectors. This PSU is the highest rated 80 Plus Platinum PSU [H]ard|OCP has seen, as well as the highest from Enermax and they were not disappointed.  While it shared its design with the MaxRevo 1500W which left [H] a little disappointed, the Enermax implementation was superior and this PSU walked away with an Editor's Choice.

H_EnermaxP.jpg

"Enermax is a long standing quality desktop PSU company. It not only specifies and designs power supplies it is one of the few companies that actually build enthusiast PSUs. Enermax today moves it 1350 watt giant into "Platinum" efficiency territory with the new Platimax 1350W."

Manufacturer: Corsair

Introduction and Features

Corsair continues to bring a full line of high quality power supplies, memory components, cases, cooling components, SSDs and accessories to market for the PC enthusiast and professional alike.  Corsair's updated Professional Series HX power supplies include four models; the HX650, HX750, HX850 and HX1050.  All of the power supplies in the Professional Series feature modular cables, premium quality components, an energy-efficient design (now 80 Plus Gold certified) and quiet operation; and they are backed by a 7-year warranty and lifetime access to Corsair's comprehensive technical support and customer service. The most obvious differences between the new models and the old Professional Series HX PSUs are the new 80 Plus Gold efficiency certification (upgraded from 80 Plus Silver) and the ability to operate in fanless-mode.

2-hx850_psu_sideview_cable_.jpg

Here is what Corsair has to say about their new Professional Series HX PSUs:

"Legendary Performance and Reliability

Corsair Professional Series HX power supplies are designed for PC builders and upgraders who need a highly efficient, quiet, and supremely-reliable power supply, with a modular cable-set that makes installation a breeze.

Quiet Operation at Low Loads

Thanks to their highly-efficient design, Corsair Professional Series power supplies generate minimal heat, and are able to operate in a silent, fully-fanless mode at up to 20% of the PSU’s maximum load (170W for the HX850). This means that Professional Series HX PSUs will be completely silent when you’re performing less intensive tasks, such as web browsing or chatting in forums. And the thermally-controlled fan spins up gradually above 20% load, so that it still operates quietly during normal use and when gaming. Basic PC power supplies have fans that spin all the time your PC is on – whether you’re pushing your graphics card to the limit or just surfing the web – making them noisier and more intrusive.

Modular Cables for Easy Installation

Professional Series power supplies have a comprehensive modular cable set that allows you to use only the cables you need for your particular set of components. The benefits of this include a cleaner, neater installation, and that ‘professionally-built’ look, plus increased airflow through the case due to reduced cable clutter. The cables are also long enough to support full-tower cases.

80 PLUS Gold: High Efficiency – Low Heat

Efficiency is the measurement of how effectively a power supply converts AC power from your wall outlet to the DC power used by your PC’s components. If your power supply isn’t efficient, it will generate more heat, which requires more cooling and more fan noise. And, it might even affect your power bill.

Professional Series HX PSUs are among the most efficient on the market. Each model has 80 Plus Gold certification, which ensures up to 90% energy-efficiency. This helps to keep your PC cool and quiet, and it may even save you money too.

Reliable

Professional Series HX PSUs are built with premium components, such as 105°C capacitors, and are capable of continuous power delivery at a temperature rating of 50°C, ensuring maximum performance and reliability even in the most demanding and hot-running performance PCs.

The Corsair Advantage

Corsair Professional Series PSUs are backed by a reassuring 7-year warranty and comprehensive customer support via telephone, email, forum and the Tech Support Express helpdesk."

EVGA's SuperNOVA NEX1500 Classified 1500W PSU is more than just a source of power that would satisfy even a certain stand up comedian turned TV star, it also features some rather interesting extras.  Some of the features bear a resemblance to those found on the Corsair AX1200i Digital ATX 1200W which Lee reviewed a short while ago, like programmable rails and software which allows monitoring and control of certain aspects of the PSU.  While the 10 year warranty is a good sign, TechPowerUp! found a few questionable results from the tests they ran.

TPU_psu_top_close.jpg

"EVGA's new SuperNOVA NEX1500 power supply packs a great deal of features with the most fascinating being its enormous capacity, reaching 1500 W and up to 1650 W, when overclock mode is enabled. Combined with software monitoring and control, the fully modular design and the sleeved cables this is a PSU enthusiast's dream come true."

EVGA Launches NEX1500 Classified PSU, Overclocks to 1650W

Subject: General Tech | August 23, 2012 - 10:31 AM |
Tagged: PSU, power supply, evga, 80 Plus Gold, 1650W

EVGA, a company most well-known for its line of graphics cards and enthusiast motherboards, has rounded out its computer offerings by announcing a power supply product. The NEX1500 Classified power supply (PSU) is a first for the company, and is released under the company’s high-end “Classified” series.

120-PG-1500-XR_XL_4.jpg

The NEX1500 Classified is a fully modular power supply that is able to run off of 110 or 230 VAC. When run on 110 volt, the PSU is rated to provide up to 1500 watts. Even better, EVGA claims an efficiency rating of 80 PLUS Gold. Interestingly, the PSU is “overclockable,” in the sense that it can deliver up to 1650 watts when hooked up to a 230 volt circuit. The overclocking is done in a piece of SuperNOVA software. The software allows the following monitoring and adjustment functions:

  • Monitor voltage
  • Monitor current draw for each rail
  • Monitor power used
  • Monitor efficiency
  • Change fan profile
  • Adjust the +12V rail (and configure single or multi rail mode) 

Other features of the EVGA power supply includes Japanese capacitors throughout and a fully modular design–even the 24-pin ATX cable is modular which is nice to see.

120-PG-1500-XR_LG_3.jpg

The cables are all sleeved in the black and red EVGA color scheme. It comes with the following cables:

  • 1 x 24-pin ATX
  • 2 x 8-pin EPS12V (the CPU power socket on the motherboard)
  • 16 x 6+2-pin PCI-E
  • 3 x 6-pin PCI-E
  • 12 x SATA
  • 8 x Molex
  • 2 x Floppy
  • 1 x USB (that’s one I’ve not seen before on a PSU!)

The EVGA NEX1500 is packed with lots of features that enthusiasts like to see, but it will cost you. It has an MSRP of $449.99 USD and will be available later this month (August 2012). Fortunately, EVGA seems confident that this will be the only PSU you will need for a while as it comes with a 10 year warranty. You can find more information and photos on the EVGA product page.

It is interesting that the company’s debut product is one on the very high end of the market. It could be a good thing, however. If reviewers find it to be a quality product, it will be the ideal platform for the company to work from to create lower cost (and lower wattage) models for the rest of the computer market.

Get Platinum power for about $100

Tagged: PSU, antec, 80plus platinum, Earthwatts Platinum 650W

At $120 on NewEgg, the Antec Earthwatts Platinum is not a bad choice for those looking for power and efficiency.  Although it is SLI rated, with only two 6+2 PCIe power connectors you will need to rely on molex adapters to run two cards and at 650W they will not be current flagship models.  Legit Reviews saw some questionable results while testing but for a PSU of this price, especially such a quiet and efficient one, it comes with a recommendation to stop worrying and pick it up.

LR_earthwatt.jpg

"When it comes to performance, besides its high electrical efficiency which is expect from an 80Plus Platinum unit. The Earthwatts Platinum 650W PSU also excels in acoustics, with the unit running entirely silent across the entire nominal load range. The high efficiency also allows it to operate at fairly low temperatures as little energy is wasted as heat. Even though most hardcore enthusiasts would find this unit's electrical performance mediocre, we believe that the ripple suppression and voltage regulation of the Earthwatts Platinum 650W unit is more than acceptable for a sub-$100 product..."

Tagged: corsair, Professional Series AX1200i, PSU, modular psu, kilowatt

The reason that Corsair's new Professional Series AX1200i is called a digital power supply is due to the presence of a digital signal processor inside the PSU.  The advantages are likely to due with the reduced complexity of the internal design than due to the DSP being a miracle, however there is more to it than just smooth voltages.  With the USB Corsair Link interface you can use the bundled software to monitor the three main voltage rails, the 24-pin connector's 12V line, the AC voltage at the wall socket and there are current trackers for all of the PCIe power connectors as well.  If you obsess over power management and happen to need more than a kilowatt of power, check out Corsair's latest offering at The Tech Report.
