If you have quad SLI/Crossfire, dual CPUs and dozens of hard drives you might find yourself in a position where a 1600W PSU is something you actually need.  That is where the LEPA 1600W PSU come in, with 10 eight pin PCIe connectors and 14 SATA connectors as well as numerous molex connectors for your fans.  [H]ard|OCP's testing showed that this PSU did deserve it's 80 PLUS Gold rating and more importantly it provided solid power.  It sports a decent price, in fact it is almost the same price as several PSUs which are rated at 250W lower.  There was something about the unit which kept it from earning a Gold Award but you will have to read the full review to see why [H] decided on Silver for this PSU.

"LEPA is an Ecomaster company and Ecomaster distributes Enermax products and has Enermax design the LEPA PSU line. So what are our expectations from the current ultimate desktop PSU packing a whopping 1600 watts? Should it be better than a four year old 1600 watt power supplies on the market?"

Can CoolerMaster actually provide 1300W of Silent power

Subject: Cases and Cooling | April 3, 2012 - 06:50 PM |
Tagged: Silent Pro Hybrid 1300, modular psu, kilowatt, coolermaster, 80 Plus Gold

It seems hard to imagine that a PSU that provides more than a kilowatt of power can be considered quiet but Cooler Master goes even further with their Silent Pro Hybrid 1300 Watt PSU.  Rated for 80 Plus Gold and able to provide 1260W @ 105A on its single 12V rail this beast of a PSU and its eight 6+2 pin PCIe power connectors should be able to power any graphics system you might want to dream of setting up.  Part of the Silent comes from a unique fanless mode, when load is under 200 watts and the temperature below 25C the fan powers off.  The other modes are manual and auto, which anyone with a recent video card will be familiar with.  From the 5 year warranty to the solid power that this PSU provides, Hi Tech Legion found a lot of things to like about this premium PSU.

"With the Silent Pro Hybrid 1300 Watt PSU, Cooler Master has actually added usability features to a category typically limited to simply watts and amps. The Cooler Master Silent Pro Hybrid 1300 Watt PSU goes beyond being an 80+ Gold, 105A single 12V rail behemoth, and incorporates a 7V chassis fan rail along with a 5.25” Dual Fan Control Module. After all, if you have need for 1300 watts of power, odds are good you are going to have more than a fan or two running in your case, and what better place to power and control them from than directly from the PSU? In addition to a single-channel, continuously variable controller for up to three chassis fans, the fan control module offers PSU fan control in addition to “PSU Fanless Mode”."

(80+) Gold Plated PSU roundup

Subject: Cases and Cooling | March 26, 2012 - 05:22 PM |
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."

Enermax doesn't feel the need to brag about the efficiency of the new Revolution87

Subject: Cases and Cooling | March 1, 2012 - 02:54 PM |
Tagged: PSU, modular psu, enermax, Revolution 87, 80 Plus Gold

The Enermax Revolution87+ 1000W PSU can distribute almost its entire peak capability across its four 12V rails at a maximum of 83A.  After their testing [H]ard|OCP proclaimed that this is another step forward in PSU design for Enermax, retaining solid construction and power generation needed by users as well as increasing efficiency and lowering noise.  Perhaps the most laudable thing Enermax did with this unit was to market it as 80+ Gold even though it actually meets Platinum standards.  That is the opposite of most PSU marketers whose PSUs tend to barely meet the claimed efficiency or to not meet it at all when tested by reviewers.

"Enermax is and has been a favorite brand with HardOCP for many years now. Today it is showing off its new Revolution 87+ series suggesting 87% efficiency or better at all times. Coming in at a full kilowatt of supplied power, designed with ZERO LOAD sleep states in mind, and 24-7 at 50C performance, this should be one tough PSU."

NZXT reveals a full Hale hand of PSUs

Subject: Cases and Cooling | February 7, 2012 - 05:09 PM |
Tagged: PSU, nzxt, modular psu, HALE90-750-M, HALE90-1000-M, HALE82-850-M, HALE82-750-M, HALE82-650-M, 80 Plus Gold, 80 Plus Bronze

X-bit Labs collected five PSUs from NZXT's HALE82 line including the HALE82-650-M, HALE82-750-M, HALE82-850-M, NZXT HALE90-750-M and HALE90-1000-M.  All of the PSUs are rated at least 80+ Bronze with the HALE90 models reaching 80+ Gold ratings.  This is a definite boon for those who plan on running the 1000W model.  All are 12V PSUs, with an internal converter to provide 3.3V and 5V, which means that these PSUs can provide in the neighbourhood of 99% of its maximum amperage to the 12V line to keep those GPUs fully fed.  Head on over and read through the whole review or else choose the PSU with the wattage appropriate for you to examine.
