For those systems with multiple GPUs and serious storage a 500W PSU just won't cut it, you need to look to the 1000W+ models.   Of course with great power comes great cost, so having an 80 Plus Platinum rating can be a good thing.  The Kingwin LZP-1000 will give you both the power and efficiency with modular cabling to ensure your case stays nice and clean.  At the sticker price of $230 [H]ard|OCP calls this PSU a steal, top notch performance at a bargain price.  Check out this Gold Award winning PSU at [H].

"Kingwin does not bring a huge number of power supplies for review, but when it does bring one to our attention it is usually a very worthy competitor. Today is no different. This new 1 kilowatt computer power supply brandishes sought after modular connections along with a very efficient design that has very much impressed us."

Cooler Master's fully controllable Silent Pro Hybrid 850W PSU

Subject: Cases and Cooling | January 4, 2012 - 11:18 AM |
Tagged: Silent Pro Hybrid 850W, PSU, modular psu, cooler master, 80 gold

Cooler Master's new Silent Pro Hybrid 850W PSU differs somewhat from your average PSU.  Like many it is fully modular and uses a single 12V rail which is becoming common for high wattage PSUs.  The 80+ Gold rating is a little rarer but what really makes it stand out is a faceplate that acts as a fan controller.  The controller allows a variety of speeds to be set for the PSU fan as well as three system fans and can even switch the PSU into fanless mode to make this PSU truly silent.  Guru3D put the PSU through its paces and were truly impressed by this ~$200 PSU, see why in the full review.

If you are looking for a little less power, Lee just wrapped up his review of the Corsair TX550M and TX750M PSUs.

"Cooler Master launched the new Cooler Master Silent Pro Hybrid PSU series. The end result as such is enticing alright, a very nice power supply rates 80+ gold, that comes with a modular design and one big massive 12V rail, which we all like so very much. Carrying a 80+ Gold certification (90% efficiency at typical load) , being modular, with included fan controller and having good looks yeah the Silent Pro Hybrid promises to be an excellent product series."

Corsair's single 12V rail HX1050, there's a new Professional in town

Subject: Cases and Cooling | December 2, 2011 - 12:57 PM |
Tagged: PSU, kilowatt, modular psu, corsair, hx1050

Over at [H]ard|OCP you can catch a review of Corsair's new HX1050 Professional PSU, the same model that Lee handed a Silver Medal to.  The big change to this member of Corsair's Professional series is that this model sports a single 12v rail unlike the dual rail design on the HX1000.  That single rail can handle 87.5 amp, which is why there are a half dozen 6/8 pin PCIe connectors.  This PSU has owners of multiple GPU systems in mind.  By the end of the review [H] could not call this PSU better than the HX1000 but did like many of its traits; likely why it walked away from that review with another Silver Medal to show off.

"Professional Series power comes to us this time from Corsair in the form of its new HX1050. It is boasting over 1 kilowatt of solidly efficient power for the computer hardware enthusiast with a semi-modular cable system. We will see if this PSU is fit for enthusiasts and if it lives up to its efficiency statement."

A six pack of 600+ PSUs

Subject: Cases and Cooling | November 23, 2011 - 03:06 PM |
Tagged: antec, Enhance, Hiper, scythe, PSU, modular psu

X-bit Labs assembled a number of PSUs to compare; the Hiper M600 650W, Scythe's Stronger 600W, Antec's Neo ECO 620C 620W, Enhance's EPS-1280GB4 800W and the Scythe Chouriki 2 850W.   Most of the models are modular and several have 80+ ratings but unfortunately none stood out as shining examples of a PSU in their particular wattage.  Still, it is nice to see a quick comparison of common PSUs found in prebuilt systems, such as the Antec Neo ECO which was pulled from an Antec Sonata IV.  Check it out here.

The SilverStone Strider Gold 750W deserves its name, but for the wrong reason

Subject: Cases and Cooling | November 16, 2011 - 12:17 PM |
Tagged: modular psu, 80 gold, Silverstone, strider gold 750w, 750w

The SilverStone Strider Gold 750W offers good performance but unfortunately demands a premium price.  Overclockers Online had a hard time getting around that fact when they reviewed this unit.  There is nothing bad about the PSU, the solid performance of the single 12V rail at 62A will keep most users happy as will the amount of SATA and PCIe connectors.  The 5V rail does vary by about 3% but is still well within specifications.  Still, there are competitors out there delivering the same performance and charging less money for their units. 

OCO_silverstone_strider_gold750W_6.jpg

"The Strider Gold 750W does have a quite a bit of good points going for it and a few excellent ones, namely: efficiency and some pretty decent line regulation on the 12V rail (which reasonably, we care quite a bit more for than the 5V rail). The unit is also built extraordinarily well, inside and out. Still, while we can hardly discount the fact that the Strider Gold 750W is priced just a wee bit higher than it should, that decision is for the individual and despite priced a tad higher than other units, the Strider Gold is still a solid power supply."

1000W of silent power from Seasonic

Subject: Cases and Cooling | November 7, 2011 - 10:24 AM |
Tagged: seasonic, Platinum-1000, modular psu, kilowatt, 80 platinum

[H]ard|OCP got their hands on a very impressive kilowatt class PSU from Seasonic, the Platinum-1000.  In their testing it did come incredibly close to the results at 80Plus, backing up the claim that this PSU deserves 80+ Platinum.  As well, the hybrid fan design ensures near silent performance though [H] were hard pressed to hear the unit even when the fan was running full blast.  The power provided was rock solid with barely a trace of ripple or noise on the lines.  By the end [H] decrees that "The Seasonic Platinum-1000 is quite literally THE power supply on the market today.

H_seasonic1000.jpg

"Seasonic breaks the Platinum efficiency barrier with its new 1 kilowatt computer power supply. We generally know if it has Seasonic branding, it is a good PSU. But we all want to know if it is a great PSU. We all know that Seasonic means "quiet" as well and believe it or not this PSU can be dead silent."

It comes with a full compliment of all modular cables, including dual EPS connectors and eight PCI-E connectors for multiple high-end graphics adapter support. High efficiency also means less waste heat, which should result in lower operating temperatures and less fan noise.

Kingwin's silent and powerful new Stryker 500W PSU

Subject: Cases and Cooling | October 19, 2011 - 02:07 PM |
Tagged: Kingwin Stryker 500W, Kingwin, 80 platinum, modular psu

The latest victim of [H]ard|OCP's PSU torture chamber comes from Kingwin; the same fanless 500W Stryker model that Lee reviewed a short while ago.  They were impressed with the so called overclocked mode, which allows the PSU to produce 600W and still manages not only to retain stable rails but also an efficiency rating above 89%.   It soared through their torture test and managed to stay at the rated 0dB, of course.  Their final verdict was very positive, though like Lee they warn that silent PSUs are more expensive and probably won't attract many buyers who can buy the same level of quality in a PSU with active cooling for significantly less money.

H_Kingwin.jpg

"Kingwin, might not be the first name that comes to mind when looking for a top-shelf PSU, but in our testing Kingwin has been very consistent with quality PSU builds. Today we look at its silent 500 watt computer power supply. We all know what happens to computer component cooling when we go silent. Can Kingwin pull off another big win?"

Enermax - They've gone to platinum!

Tagged: enermax, 80 platinum, platimax 1200W, kilowatt, modular psu

Enermax has really taken the cake with their new Platimax 1200W PSU, so named because it carries an 80+ Platinum rating.  That high of an efficiency rating is very rare and is usually seen on PSUs in the 500W range but Enermax has more than doubled it.  You get over a half dozen 8pin PCIe power plugs as well as a plethora of SATA and other power plugs.  If you need this much power for your rig it is worth investigating this level of power efficiency as it will save you money eventually.  [H]ard|OCP gave this PSU a Silver Award, missing out on Gold due to pricing only.

"Enermax is one of our long time favorite brands when it comes to PSUs. Enermax has proved over and over again that it is one of the world's premier PSU builders. Today it steps into a realm that is tough to compete in and in fact has not ever been seen by any other PSU builders as of yet. 1200 watts that is 80 Plus Platinum certified."
