The upper echelon of the Seasonic X-Series, 850W of solid power

One drawback to impressing [H]ard|OCP with the quality of one of your PSUs is that the bar is now set that much higher for the next model they review.  Seasonic is one such company that has a great reputation that they have to live up to with their new X-850 PSU.  The half dozen PCIe 6+2 power plugs are a good start, as is being able to provide up to 99% of total power to the four 12V rails and the fully modular cabling is always appreciated.  The real question is how it fared on the test bench, so go find out if it just makes it or if it passes the torture test with flying colours.

Seasonic is a long time favorite of HardOCP editors as you will find a Seasonic PSU in many builds we have done over the years. Today Seasonic pushes its X-Series forward just a bit more building its first gold efficiency rated fully modular enthusiast power supply. But will it blend?"

XFX claims there is something different about their ProSeries 650W

Subject: Cases and Cooling | March 27, 2013 - 03:17 PM |
Tagged: xfx, PSU, ProSeries 650W

The XFX ProSeries 650W PSU is mostly modular, with only the ATX connector attached, has a 135mm cooling fan and can send 98% of its total wattage to the single 53A 12V rail.  With four 6+2 PCIe power connectors you will be able to handle multiple GPUs and the 8 SATA connectors should allow you as many storage devices as you need.  Unfortunately [H]ard|OCP discovered something about the 5 year warranty which greatly displeased them; unless you register your PSU within 30 days of purchase, you only receive a 2 year warranty.  If you are strictly concerned about the quality of the power this PSU delivers and are ambivalent towards the warranty, this PSU passed [H]'s torture tests handily which is something not every PSU can claim.

"XFX has long and actually very solid history of producing high quality enthusiast power supplies. We have consistently found XFX PSUs worthy of [H] Editor's Choice Awards. Today the XFX ProSeries 650W promises "One Rail, One Setup" in a PSU that is different. Let's see if that is good or bad."

A SilverStone PSU so small it uses an 80mm fan

Subject: Cases and Cooling | March 14, 2013 - 06:11 PM |
Tagged: PSU, Silverstone, SFX ST45SF-G 450W, SFF, 80 Plus Gold, modular psu, SFX PSU

If you are looking to power a small form factor system and need a fully modular PSU in order to get it into a tightly packed case as well as high efficiency the SilverStone SFX ST45SF-G 450W is a decent choice.  It is Fully modular and is an SFX PSU, which as you might remember from Lee's review means that it lacks a -5V rail, not a necessary feature in today's systems.  [H]ard|OCP granted an award to this PSU, not because it is the best 450W PSU available, which is not, but because it is the best fully modular SFX PSU they have seen and they realize sacrifices have to be made in a PSU which is barely able to fit an 80mm fan inside.  Check out the full review to see if you think this PSU is worth the price premium or if you might just consider a larger PSU for your HTPC.

"Silverstone is one of our favorite computer power supply builders as the company has a tremendous track record when it comes to high quality and quiet power for our desktop systems. Today we look at something a bit different in terms of scale, a PSU pushing 450 watts of power in a package half the size with its sights on the SFF market."

A mid-weight PSU from Seasonic, the Platinum 660W

Subject: Cases and Cooling | February 14, 2013 - 05:47 PM |
Tagged: rosewill, PSU, Platinim 660, modular psu, 80plus platinum

If the 1000W Rosewill PSU that Lee just reviewed is more power than your system needs, [H]ard|OCP has a slightly less powerful 660W 80Plus Platinum PSU you could consider that Lee has also looked at.  At $150 it is fairly expensive for a 660W PSU, but a 7 year warranty and a Platinum efficiency rating do not come cheap.  With four 6+2 PCIe connectors and up to 55A on the 12V rail and an unparalleled peak change of 0.01v this will solidly power several GPUs.  [H] was so impressed that they couldn't think of a PSU to contrast against, this unit is miles ahead of the competition when it comes to the purity of the voltages provided.

H_rosewill660.jpg

"Seasonic's new SS-660XP comes to us boasting high end PSU features in what we can consider a smaller wattage package than what we are used to seeing. This PSU has a fully modular design, great efficiency, optional Hybrid fan control allowing fanless, silent, and normal cooling modes. Does Seasonic have another winner?"

Kingwin's new Power Force PSUs arrive

Subject: Cases and Cooling | January 29, 2013 - 01:46 PM |
Tagged: PSU, Kingwin, Power Force 850W, modular psu

Kingwin's $110 Power Force 850W PSU is not as well appointed as other 850W PSUs but is also much lower in price.  With four 6/8 pin PCIe connectors and 8 SATA power connectors some users might feel a bit cramped but with 70A of power on the 12V line it seems that the unit can be useful for many. [H]ard|OCP tested the PSU to see if it is indeed worth the purchase price and were glad to see it pass all their tests, though perhaps not with flying colours.  This is the first Power Force PSU that they have seen, if Kingwin can keep the quality high and the price low they may make some inroads into recognized PSU suppliers.

H_PowerForce850W .jpg

"While not a "go to" enthusiast brand, Kingwin has produced some excellent computer desktop power supplies over the last five years and these have usually be great values. Does Kingwin continue the trend with its new Power Force 850W model sporting good efficiency, modular cabling, and reasonable pricing."

Seasonic's new G-series PSU is rated gold in more ways than one

Subject: Cases and Cooling | January 14, 2013 - 03:26 PM |
Tagged: PSU, 80 Plus Gold, Seasonic G-Series, G-550

Seasonic's G-550W provides a bit more than just 550W and a 45A 12V line, modular cabling and an 80 PLUS Gold rating are also included in the $85 price tag.  Those features do not in themselves guarantee that this PSU is worth picking up which is why [H]ard|OCP strapped it into their torture chamber to test the quality of power you can expect from the PSU.  The news is good for Seasonic's G Series, once the power was shut off and the testing completed this PSU walked away with an Editor's Choice Gold Award as [H] felt that not only does this PSU deliver everything they expected it to, in some cases it was "fighting above its weight".

H_seasonicG550.jpg

"The Seasonic G Series PSU is here for review in its 550 watt capacity and it looks to be a return to basics for the company with this being basically a "no-frills" unit that has been released without much fanfare. But the basics for Seasonic usually outline what you truly need in a PSU; reliable clean power with a low sound profile."

FSP's new Raider series of PSUs

Subject: Cases and Cooling | January 7, 2013 - 04:52 PM |
Tagged: PSU, FSP RAIDER, 750w

FSP has been making PSUs for a long time now, usually providing decent quality components that might not stand out against other companies flagship models but that do a decent job for what they are needed for.  That is repeated in the Raider series as they chose a non-modular design and only four 6+2pin PCIe connectors though it does have an 80 PLUS Bronze rating, both of those choices helped keep the price down as it is currently $80 on NewEggPrice is not everything as [H]ard|OCP proved when they put this PSU through their torture tests and watched it provide voltages well out of specifications as well as offering poor support.

H_Raider.jpg

"With single GPU and CPU enthusiast desktop computer systems coming down in power, mid-level power supplies are once again becoming the sweet spot. FSP claims its new RAIDER series PSU is the "best choice in performance." We put its RAIDER 750 watt unit to the test to see if it is the best choice for you."

Rosewill Announces 1600W Hercules PSU

Subject: Cases and Cooling | December 3, 2012 - 08:56 PM |
Tagged: rosewill, PSU, power supply, 80 PLUS Silver, 1600w

Rosewill recently took the wraps off of a monster of a power supply that is rated to deliver 1600W of power. The Hercules 1600W PSU is an 80+ Silver design that will provide efficient power for quad CrossFire X or Nvidia SLI multi-GPU setups. It measures 5.9” x 3.4” x 9.5” and should fit within most full ATX cases without issue.

 

Rosewill 1600W PSU.jpg

Other features include sleeved cabling and a 135mm “silent” fan that has an automatically adjusting RPM setting as well as a Turbo button that will spin the fan up to its maximum speed.

Where the PSU really stands out though is in the sheer wattage and number of PCI-E power cables. It features two 12 volt rails at 110A and 50A each. Rosewill has divided the rails such that 12V1 handles all of the PCI-E power connectors (up to 1320W) and the 12V2 rail rated at a maximum of 600W and is used for all the other 12V connections.

Rosewill 1600W.jpg

The included power cables are as follows:

  • 16 x 6+2 pin PCI-E
  • 16 x SATA power
  • 6 x 4 pin molex
  • 2 x 4 pin floppy power
  • 1 x 8 pin EPS
  • 1 x 4+4 pin EPS
  • 1 x 24 pin ATX

Needless to say, it has an impressive number of power cables. You might have a hard time finding enough graphics cards to use even half of the PCI-E power cables, for example. Fortunately, it has a semi-modular design (the ATX and CPU power cables are non-removable) so that you will not have to find enough room to hide all of the excess cables in the 5.25” bays (heh).

The 1600W Hercules power supply is available now with a price of $399 USD. While it will be overkill for most computers, it is impressive nonetheless and would be well suited to powering a rig with dual Powercolor Devil 13 7990 GPUs.

Nine Middle Weight PSUs battle it out

Subject: Cases and Cooling | November 21, 2012 - 04:18 PM |
Tagged: PSU, modular psu, corsair, Chieftek, cooler master, zalman

The 600-700W range is very popular with enthusiasts who either have a pair of fairly powerful GPUs or a single top of the line GPU, as they don't quite need a kilowatt class PSU.  X-bit Labs put together a roundup which features 9 PSUs from Corsair, Chieftek, Cooler Master and Zalman some modular and some with permanently connected wiring.  It was the Corsair TX650 which received the Recommended Buy award though Cooler Master came close to winning as well.  Some of the other models fared poorly thanks to the lack of proper voltage regulation or in one case fan regulation.  Check out the full review here.

"We would like to talk about nine power supply units from the most popular 600-700 W wattage range, which represent six different series of devices from four manufacturers: Chieftec, Cooler Master, Corsair and Zalman."
