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 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."

SilverStone has a long-standing reputation for providing a full line of high quality enclosures, power supplies, cooling components, and accessories for PC enthusiasts. With a continued focus on smaller physical size and support for small form-factor enthusiasts, SilverStone recently introduced the new SX500-LG. There are currently five power supplies in the SFX Series, ranging in output capacity from 300W to 600W. The SX500-LG is the first one to feature an extended chassis. The SX500-LG enclosure is 30mm (1.2”) longer than a standard SFX chassis, which allows using a quieter 120mm cooling fan rather than the typical 80mm fan used in most SFX power supplies.

3-Compare.jpg

150mm                                130mm                              100mm

The new SX500-LG SFX-L Series power supply was designed for small form factor cases but comes with an ATX adapter plate so it can be used in a standard ATX enclosure as well. In addition to its small size, the SX500-LG features high efficiency (80 Plus Gold certified), all modular flat ribbon-style cables, and provides up to 500W of continuous DC output. The SX500-LG PSU also operates in semi-fanless mode (cooling fan turns off at low power).

Note: We have seen rumors on the web about the new SX500-LG power supply being a re-packaged version of the SX600-G that SilverStone recalled awhile back. Rest assured it is not. The SX600-G is a completely different PSU made by Enhance and the new SX500-LG is made by High Power. And yes, the SX500-LG is officially listed as an 80 Plus Gold certified PSU (10-22-2014).

Here is what SilverStone has to say about the new SX500-LG PSU: “For small form factor enthusiasts, the standard SFX power supply form factor has an excellent combination of size, power, and affordability. At 100mm deep, however, the standard SFX PSU is also limited in fan size to 80mm. While advances in engineering and components have modern high-end SFX PSUs quieter than ever, there is still inherent limitation with 80mm fan’s ability to dissipate heat at maximum loading conditions while maintaining satisfactory noise profile for users sensitive to higher-pitch sounds. With this in mind, SilverStone has released a “lengthened” variation of the SFX form factor called, SFX-L. With 30mm of added depth, a SFX-L power supply has enough room to fit a 120mm fan, thus its maximum load noise can be not only lower in intensity (via slower fan speed), but also lower in pitch (due to larger fan size). The first model to debut in the SFX-L will be the SX500-LG, a 500W model that includes all features available from top of the line SFX SilverStone PSUs such as 80 Plus Gold efficiency, modular flexible flat cables, and semi-fanless capability. An ATX adapter bracket is included as well to enable users to install this PSU into any small or even larger cases that do not have SFX mounting holes.

SilverStone SX500-LG V1.1 SFX-L Series Power Supply Key Features:

•    New SFX-L form factor (and ATX via included adapter)
•    Silent running 120mm fan with intelligent semi-fanless operation
•    500W Continuous DC output (up to 40°C)
•    High efficiency with 80 Plus Gold certification
•    100% Modular cables, flat ribbon-style
•    Strict ±3% voltage regulation with low AC ripple and noise
•    All Japanese made capacitors for reliable operation
•    Powerful single +12V rail with 40A (480W)
•    Two PCI-E 6+2 pin connectors
•    Protections: UVP, OVP, OPP, and SCP
•    Universal AC input and Active PFC
•    MSRP $99.99 USD

Earlier this year we took a look at SilverStone’s ST1500-GS power supply unit, which currently has the highest rated output in the Strider Gold S Series. Today we are looking at SilverStone’s second generation Strider Gold ST75F-GS V2.0, which is a 750 watt power supply that comes housed in a short chassis; only 140mm (5.5”) deep for easy integration. It’s nice to get a different model from the same series in for review to see how the series overall performs. SilverStone claims the Strider Gold S Series are the world’s smallest, full-modular ATX power supplies.
