Introduction

Corsair continues to expand their extensive power supply lineup with the addition of two new small form factor (SFX) units, the SF450 and SF600. The SF Series power supplies are fully modular and optimized for quiet operation and high efficiency. Both power supplies feature Zero RPM Fan Mode, which means the fan doesn’t start to spin until the power supply is under a moderate to heavy load. The SF450 and SF600 are 80 Plus Gold certified for high efficiency and come with a 5-year warranty.

While the SF Series is designed for use in small form factor enclosures, Corsair’s SF Series power supplies can also be used in standard ATX cases to save room via the optional SFX to ATX adapter bracket. As you can see in the photo below, the SF Series power supply is much smaller in all three dimensions than a standard ATX power supply. We will be taking a detailed look at the new SF600W power supply in this review.

FSP's new Hydro X series; technically the less expensive model?

Subject: Cases and Cooling | June 6, 2016 - 06:55 PM |
Tagged: fsp, PSU, Hydro X, 650W, 80 Plus Gold

With all the hoopla and brouhaha caused by Computex last week some smaller launches were missed, such as the FSP Hydro X 650W PSU.  This particular PSU is non-modular but does carry a five year warranty, an 80 Plus Gold rating and a single 12V rail capable of providing 649.92W @ 54.16A.  [H]ard|OCP's testing showed it to be a solid PSU, providing stable power and meeting with the claimed standards.  Unfortunately there is currently a bit of an issue, though FSP is working to resolve it.  This PSU sells for $95 but the previous fully modular model can be picked up for $85 or less, even though the MSRP is technically higher.  [H] reached out to FSP about this issue and you can see how they plan to resolve the issue in the full review.

"FSP does not have much to say about its Hydro X in terms of marketing speak, but it does hit the high points that enthusiast system builders are looking for: "Silent operation, High efficiency ≧ 90%, Full Japan-made electrolytic capacitors, Powerful single +12V rail design, Ribbon cables, and Complete protection: OCP, OVP, SCP, OPP, OTP."

Take a chance on Rosewill's Valens-700?

Subject: Cases and Cooling | May 9, 2016 - 06:39 PM |
Tagged: rosewill, Valens-700, 700W, 80 Plus Gold

Saving a bit of money on your PSU can seem like a good idea but the importance of a solid PSU is often overlooked.  Rosewill has been around for quite a while but their PSU's do not tend to end up in a lot of high end rigs.  [H]ard|OCP took a look at their new Valens-700 which looks good on paper with a single 12V rail, 80 PLUS Gold certification and the hope that part of the savings is due to the non-modular design.  Unfortunately once it was strapped onto the test bed it failed many tests and did not receive a passing grade.  Check out the full review for the specifics and recommendations on better PSU at around this price point.

"While Rosewill is likely not a go-to computer power supply brand to most people, we have been surprised with Rosewill's quality on two of its PSUs over the last couple of years. Today we review an $80 700 watt Rosewill unit that is rated for Gold efficiency, and well ... that is about all that marketing has to say about its Valens-700."

FSP on the inside and outside, the Hydro G 650W PSU

Subject: Cases and Cooling | April 22, 2016 - 05:50 PM |
Tagged: fsp, HYDRO G, 650W, modular psu, 80 Plus Gold

FSP provides the insides to many of the PSUs you see sold from Corsair, Zalman, Antec and just about every other provider at some point in the past.  They also occasionally sell them under their own brand name, which brings us to the Hydro G 650W fully modular PSU that was recently reviewed at [H]ard|OCP.  The PSU has a single 12V rail capable of providing 649W @ 54.16A, with the four 6+2 PCIe connectors it will handle many dual GPU systems.  It comes with 80 PLUS GOLD certification and a five year warranty and is available for around $75.  FSP's experience shows in the design and performance of this PSU as it walked away with a Gold Award and hearty recommendations.

"While FSP may not be a PSU brand that is on the tip of your tongue, we have been reviewing FSP computer power supplies now for 8 years, and the fact of the matter is that these units have been getting better and better over time. Where does the new Hydro G 650W fit into that progression?"

Fatal1ty lends his Firepower to this 750W PSU

Subject: Cases and Cooling | January 14, 2016 - 08:44 PM |
Tagged: modular psu, firepower 750W, fatal1ty, 80 Plus Gold

Bear with us on this one as there is a long strange story behind the new PSU maker which calls themselves Firepower.  A long time ago was PSU maker that ruled the roost who called themselves PC Power & Cooling, charging a premium over the competition but being worth every penny.  As the markets changed PCP&P found themselves lagging and so an apparently successful company called OCZ purchased them wholesale and begat their own line of PSUs.  Sadly all was not as it seemed at OCZ, the deals they offered were indeed too good to be true and to survive they had to amputate some portions of themselves and sell them.  The PSU portion, including the patents, was sold in 2014 to a new company which called themselves Firepower Technology and so we come to the FirePower Fatal1ty 750W.

This PSU is rated as a 80 Plus Gold model with a 5 year warranty which speaks to the confidence of Firepower.  It uses a single 12V rail capable of delivering 62.5A and the modular cables include four 6+2 PCIe, six Molex , and eight SATA connectors, enough to power a dual GPU system. [H]ard|OCP cracked the PSU open and found it to be the same design as a SilverStone ST75F-GS V2 with a mix of components, none of which stood out as being top of the line.  In the end the design was good enough to pass every test [H] threw at it but with a relatively high price it did not come off with an award.

145072230475XBkd5Tkt_3_8_l.jpg

"The Fatal1ty Series PSUs by Firepower Technology may seem to be something new in the world of computer power supplies, but really it is not. That said, Firepower is somewhat new in the PSU world, so let's see where they are headed right now."

XFX wants to show its True Wattage with the XTR 850W PSU

Subject: Cases and Cooling | December 18, 2015 - 08:07 PM |
Tagged: xfx, XTR 850W, modular psu, 80 Plus Gold

XFX has a lot of branding on the new XTR series of PSUs including EasyRail, which means it uses a single 12V rail, on this model providing up to 840W @ 70A as well as a "True Wattage" guarantee and 80 Plus Gold. [H]ard|OCP put these claims to the test when they reviewed this PSU and did not find it lacking.  There were a few tests which the PSU did not excel at but when they tested voltage regulation this PSU finished miles ahead of the competition.  [H] also mentions that this unit was previously sold as the Pro Series Gold, the internals of the two are identical as is the serial number so keep an eye out when shopping so you can see if you can get a deal. Also worth noting is the 5 year warranty, it is always nice to see a company stand behind its products.

1449720646n3tZGej0r7_2_9_l.jpg

"XFX is targeting serious gamers and hardware enthusiasts with its new XTR Series of PSU. XFX suggest other power supplies do not always deliver, "The Wattage you see isn’t always the wattage you get." We will certainly find out if that is true with the XTR 850W PSU delivers the power and efficiency it promises in its marketing."

Thermaltake Toughpower Grand 1200W, for when you need 8 PCIe power connectors

Subject: Cases and Cooling | November 3, 2015 - 06:34 PM |
Tagged: PSU, Toughpower, thermaltake, ToughPower Grand 1200W, modular psu, 80 Plus Gold

The Thermaltake Grand series has been around for quite some time and has just been refreshed with a new model and a new price.  The PSU has a single 12V rail, capable of delivering 100% of the wattage at 100A which makes sense for a kilowatt class PSU which has eight 6+2 PCIe connectors.  It is rated at 80 Plus Gold which [H]ard|OCP's testing showed was essentially accurate, their test bed just snuck under the rating at 100% load.  With a 7 year warranty and a $240 price tag it is right in the middle of the pack for PSUs of this power, not perfect but certainly OK.

If you don't need a 1000+ watt PSU then you should revist Lee's review of the Thermaltake Toughpower DPS G 850W PSU.

14454813172NnRX0fq9s_3_4_l.jpg

"Thermaltake is back with a new 1200 watt fully modular PSU. We have used Thermaltake power supplies on our test bench literally for years with excellent results. However the Toughpower line has not always been the best value out there, but today we see a 1200 watt PSU with revised pricing."
