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.

Silver Power's 850W Gorilla

Silver Power have been making PSUs for quite a while, though they've not received much press lately which changes with their new SP-850M PSU.  Their simian logo is all over this semi-modular power supply, which has four 6+2 PCIe power connectors for multiple GPU rigs as well as a nice selection of SATA power.  OC3D was nicely surprised by the efficiency of the PSU, while rated for 80 Plus Bronze their testing showed results more appropriate for an 80+ Gold rated PSU.  OC3D are not fans of the silverback, but love the actual PSU once they realized they could run it at 983W all day long.


"It's been a few years since the angry ape first made its debut on OC3D, now it's finally back for some second helpings."

XFX's pricey Platinum ProSeries PSU performs perfectly

Subject: Cases and Cooling | June 1, 2012 - 02:40 PM |
Tagged: xfx, ProSeries 1000W, modular psu, kilowatt, PSU, 80 Plus Platinum

With a half dozen modified 8-pin PCI-Express connectors, 8 Molex connectors, and 11 SATA connectors the XFX ProSeries 1000W PSU will handle the needs of a powerful system.  The interior components are very similar to the Seasonic Platinum 1000W which is one of [H]ard|OCP's favourites.  As with the Seasonic, the XFX PSU carries an 80 Plus Platinum rating which testing proved to be essentially accurate as [H] was not going to quibble about a 0.6% difference on their review model.  You have to pay a bit more for this PSU but if you want to pick up a model that won [H]'s Editor's Choice and Gold Award then this PSU is a sure bet.


"XFX has a tremendously impressive track record here at HardOCP when it comes to enthusiast class PSUs. To date, four XFX PSU reviews, three Gold and one Silver Editor’s Choice Awards. Its new 1KW ProSeries PSU features no wires! No not like that, but rather on the inside. Let’s see if SolidLink Technology is award worthy."

Not everyone needs a kilowatt; check out Cooler Master's Extreme 450W PSU

Subject: Cases and Cooling | May 18, 2012 - 04:56 PM |
Tagged: cooler master, Extreme 2 475W, PSU

There is a lot going for the CoolerMaster Extreme 2 450W for non-power users.  It costs under $50, it is not much bigger than the 120mm fan that cools it and the 450 on the side offers enough power for many systems.  Unfortunately once Hardware Secrets opened the box and tested this PSU they would like to remove your misconceptions.  The 450 is not actually the wattage but the model number and this is, at best, a 425W PSU and the quality of power they observed from their tests is abysmal with ripple and voltage drop both exceeding specifications.  This is one PSU they recommend you avoid at all costs.


"The new Extreme 2 entry-level power supply series from Cooler Master comes in four different versions: 475 W, 525 W, 625 W, and 725 W. They don't have an active PFC circuit and, therefore, don't carry the 80 Plus certification. Let's take an in-depth look at the 475 W model, which costs only USD 50."

Corsair Enhances GS Series Power Supplies

Subject: Cases and Cooling | May 15, 2012 - 03:11 PM |
Tagged: corsair, 80 Plus Bronze, PSU, modular psu

FREMONT, California — May 15, 2012 — Corsair, a worldwide designer and supplier of high-performance components to the PC gaming hardware market, today announced major upgrades to the GS Series line of high-performance power supply units (PSUs). A new improved design boosts energy efficiency, enabling the new GS Series PSUs to achieve 80 PLUS Bronze certification while also providing quieter, fanless operation at low power loads. The newly enhanced models are available in three wattage models: the GS600, GS700, and GS800.


GS Series power supplies are designed for PC builders who want an affordable, reliable, and efficient power supply that offers visually stunning, customizable looks to match their PC. The power supplies feature user-switchable red, white or blue LED lights that can also be turned off if desired. Further customization is possible with swappable color insert rings which are available for purchase from the Corsair website.

The 80 PLUS certification program was created by utility and computer companies to drive the creation and adoption of more energy-efficient power supplies for desktop computers and servers. Corsair GS Series power supplies now have an upgraded architecture that achieves 80 PLUS Bronze certification to provide up to 85% energy-efficiency under typical usage conditions, resulting in lower energy bills and less heat.

As with all Corsair power supplies, GS Series PSUs offer class-leading voltage stability and ultra-low ripple and noise specifications, for long component life. The 140mm temperature-controlled fan also ensures that GS Series power supplies remain quiet as well as cool. Plus, by operating fanless at load levels below 20% of the model's wattage rating, each GS Series PSU significantly reduces noise levels.


"The GS Series line has been popular with PC enthusiasts who demand quiet, good-looking, and affordable power supplies they can count on,” said Ruben Mookerjee, VP and General Manager for Components at Corsair. “Now we are proud to deliver the next evolution in the GS Series PSU line, with higher-levels of energy efficiency and a new striking, customizable industrial design."

FSP goes for Gold with their 1200W Aurum PSU

Tagged: PSU, fsp, aurum pro gold, kilowatt, modular psu

As the name implies, the FSP AURUM PRO GOLD 1200 PSU's efficiency is rated 80 Plus Gold and is capable of an impressive 100A on its single 12V rail.  [H]ard|OCP was glad to see that FSP has increased the quality of materials they use in constructing the PSU.  This has paid off as the PSU received a Silver Award after passing their torture tests.


"'AURUM' means gold. So today we are showing you the "Gold Pro Gold" from FSP. That is a big name to stand behind. Once past the marketing though, the Aurum Pro Gold looks like a very solid and efficient single rail power supply for the enthusiast needing a heaping supply of wattage in a snazzy looking PSU."

Little machines need little PSUs; Seasonic's new TFX PSU

Subject: Cases and Cooling | April 16, 2012 - 06:40 PM |
Tagged: seasonic, SS-350TGM, PSU, TFX, SFF

The PSU that you have come to know in your desktop is an ATX PSU but that is not the only choice, as server techs and SFF builders are well aware.  One of the alternative standards is the TFX which retains the ATX electrical and connection specs but fits it into a 5.75" × 3.25" × 2.5" (146 x 83 x 64mm) casing.  The 350W Seasonic SS-350TGM is not designed for SLI/CrossFire systems, indeed it does not have a single PCIe connector of any type which is not a problem for the type of machine this is intended for.  If you are planning on building an ITX box with an internal PSU, or even a small custom built case, you really should drop by [H]ard|OCP to check this little PSU out.


"Today we tackle something a bit off the beaten path for us; a low power non-ATX specification power supply from Seasonic. We do know that many of our readers build systems that are not like all the others especially when it comes to crafting smaller purpose driven boxes. The 300TGM may be just what you are looking for."

(80+) Gold Plated PSU roundup

Tagged: 80 Plus Gold, PSU, modular psu, coolermaster, Silent Pro Gold 600W, Cougar, GX G900, Cougar GX G1050, OCZ ZX 1000W, Seasonic SS-850KM

X-bit Labs assembled a wide variety of PSUs which all share one characteristic for a round up.  From the lowest powered 600W to the over the top 1050W model, these PSUs all have an 80 Plus Gold rating.  You have probably seen the Seasonic, OCZ and CoolerMaster PSUs around before but the Cougar models are a little less common.  All but the Seasonic model generated positive reviews, the problem with the Seasonic model being its price; it costs more than the others but does not offer extras to justify that heightened price point.  The 600W PSUs are definitely recommended as many mid-range PSUs do not sport the 80 Plus Gold rating.  Read on to see how stable the power they provide is.


"Today we are going to talk about five power supply units from Cooler Master, Cougar, OCZ and Seasonic certified according to 80 PLUS Gold standard. Their wattage ranges from 600 to 1050 W, which provides a choice to everyone who is looking for a quality PSU."
