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.

"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 - 03:07 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.

"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."

Wattage per litre? That is a new one SilverStone

Subject: Cases and Cooling | December 1, 2015 - 06:27 PM |
Tagged: Silverstone, modular psu, 80 Plus Platinum, Strider Platinum ST55F-PT, 550W

As the title implies, the Silverstone Strider Platinum ST55F-PT is smaller than you might expect a 550W PSU to be, at just under 6" square.  That this PSU is designed for computers of a small size is reinforced by the fact that there is only a pair of PCIe 6+2 plugs, not a problem for small systems but worth noting if you were planning on adding a second GPU.  [H]ard|OCP's testing shows that the PSU easily meets the 80 Plus Platinum standard and not only was the power delivered impressively stable but the PSU also operated quietly.  It will cost you a small premium but if you need a solid, quiet and small PSU this review is worth checking out.

14468573031FRJV9CA7q_2_9_l.jpg

"SilverStone comes to us today with a Platinum rated PSU that is also billed as having a "Power Density (of) 305W per liter." While this is a bit odd, the messaging seems to be big power in a little footprint. Let's see how this "ultra silent" fully modular PSU stacks up when it comes to serving up big-time power under big-time pressure."

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

Subject: Cases and Cooling | November 3, 2015 - 01:34 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."

A good contender for powering your system, the CoolerMaster V750W

Subject: Cases and Cooling | October 2, 2015 - 03:29 PM |
Tagged: PSU, modular psu, coolermaster, V750W, 80+ gold

Cooler Master's V750W PSU is fully modular and comes with a nice selection of cabling including four PCIe 6+2 connectors and eight SATA power connectors. At 150x140x86mm (5.9x5.5x3.4") it also takes up less space than many PSUs, though not enough to fit in a truly SFF case. A single 12V rail can provide 744W at 62A which is enough to power more than one mid to high range GPU and Bjorn3D's testing shows that it can maintain that 80+ GOLD rating while it is being used.  The five year warranty is also a good reason to pick up this PSU, assuming you are not in the market for something in the kilowatt range.

"One available option soon to be available on the market for <179$, and our specimen of review today, is the CoolerMaster V750. CoolerMaster has partnered with Seasonic to produce the high quality compact “V” series PSUs which made a huge statement for CoolerMaster and told the world they were ready to push some serious power."

It has been a while since we saw a new XFX PSU

Subject: Cases and Cooling | August 18, 2015 - 03:31 PM |
Tagged: modular psu, xfx, XTR series, 550W

The XFX XTR 550W uses the Seasonic G-Series platform, a very popular choice for PSU sellers recently, with few tweaks to the overall design.  The PSU is cooled by a 135mm fan and comes with two modified 8-pin PCIe connectors, six Molex connectors, and eight SATA connectors, all of which are modular.  [H]ard|OCP strapped it into their torture room and fired it up for testing; the results of which, along with the reasonable pricing, resulted in this PSU picking up a Silver Award.  Check out the specifics right here.

"XFX comes to us today with its new XTR series power supply weighing in at 550 watts. XFX is promoting "Super Efficiency and Quality Components," "Extreme Heat Tested Capacitors," and a "True Wattage Guarantee" that touts full power at above 50C operating temperatures. Sounds exactly like our kind of PSU!"

Not everyone needs a kilowatt; nor perhaps the Cooler Master G550M?

Subject: Cases and Cooling | June 9, 2015 - 06:46 PM |
Tagged: cooler master, G550M, 550W, modular psu, 80 Plus Bronze

At 550W and an 80 Plus Bronze rating the Cooler Master G500M is not as powerful as many of the PSUs we have seen lately, then again at $75 it is also more affordable.  Unfortunately for Cooler Master the competition tends to be lower priced, with Corsair, SeaSonic and Thermaltake all having slightly better PSUs of a similar wattage for an equal or lesser price.  On the other hand Cooler Master's five year warranty is longer than any of the other brands and [H]ard|OCP feels that the G500M shows improvements over previous models as it passed all of their tests.  This particular model may not be a great choice but if CM continues to improve the quality of their budget priced models the next release might be a solid contender.

"Today we spend our time with a computer power supply from Cooler Master that is towards the lower end of the wattage scale coming in at 550 watts. Cooler Master claims "notably higher efficiency and voltage stability than other designs." We will see if its Bronze efficiency G550M PSU will stand up to our gauntlet and its own claims."

Computex 2015: G.Skill Enters PSU Market With New Ripjaws Series Power Supplies

Subject: Cases and Cooling | June 5, 2015 - 02:15 AM |
Tagged: modular psu, G.Skill, computex 2015, computex, 80+ platinum

In addition to teasing a new line of DDR4 memory, G.Skill also announced a new line of Ripjaws branded power supplies. So far, the lineup includes four models offering wattages from 750W to 1,250W. The PS750G and PS850G are rated 80 PLUS Gold while the PS850P and PS1250P are rated 80 PLUS Platinum which is nice to see (Platinum status requires 92% efficiency while the Gold models hit 90% efficiency).

GSkill Ripjaws 80Plus PSUs.jpg

The new Ripjaws PSUs are fully modular designs using all japanese capacitors and reportedly high quality components. G.Skill is using a 140mm fan for cooling that is able to spin down to zero at low loads to reduce noise levels. Safety features include support for over current, under voltage, and short circuit protection among others (OVP, UVP, OCP, OPP, SCP, OTP). Beyond that, detailed specifications have yet to be revealed. I have reached out to G.Skill to inquire about the source or OEM of these power supplies, and will update the article if they are willing to comment at this time.

Pricing and availability are also unknown at this time. G.Skill appears to be spreading its wings this year as it branches out further into other segments of the PC market. The company even has headsets and keyboards now! Are you ready to rip into these new Ripjaws PSUs? (Figuratively, of course, unless your Allyn or Lee!)

Computex 2015: Enermax Shows Off New Highly Efficient 550W Digital Fanless PSU

Subject: Cases and Cooling | June 4, 2015 - 10:02 PM |
Tagged: modular psu, Fanless PSU, enermax, computex 2015, computex, atx

Enermax has a new power supply on the market that is fully modular, fanless, and digital to boot. the new 550W PSU falls under the company's DigiFanless brand and looks to be perfect for enthusiasts wanting a silent PC.

The Enermax EDF550AWN is the first 550W power supply that is both fanless and supports digital monitoring and control. The 80 PLUS Platinum rated PSU is fully modular and supports both single and multiple +12V rail configurations (user-selectable, +12V1 and +12V2 are rated at 30 amps).

Enermax 550W Digital Fanless Power Supply.jpg

There are no fans here, just lots of ventilation for passive cooling. Enermax officially rates the power supply at 40°C (104°F) maximum operating temperature while delivering the full 550W ouptut power, but in talking with Maximum PC at Computex the company stated that in its testing lab they were able to maintain the maximum output at up to 50°C temperatures before the PSU needed to shut down.

The digital nature of the PSU is related to the ZDPMS (Zero Delay Power Monitoring System) technology which allows users to monitor and control the hardware using software running on the PC it is installed in. The application displays, in real time, the total output power, efficiency, temperature, and individual rail performance. Users can also input their $/KWh electricity costs into the TCO calculator to figure out how much it costs to run their PC and the CO2 footprint. Users are also able to use the ZDMS to adjust the current output and warning notification thresholds.

Maximum PC was on site at Computex and was able to see a demonstration of the PSU monitoring software.

Enermax has included logic to shut down the power supply in the event of overheating as well as the usual fare of safety features (OCP, OVP, UVP, OPP, OTP, SCP & SIP) They even included a bracket that locks the AC cable to the back of the power supply.

From the specifications and this review from ocaholic, the 550W Digifanless PSU is a highly efficient silent PSU with some useful extras that would be perfect for a silent gaming PC, HTPC, or audio engineering PC. It is available now for around $210 from online retailers. Looking on Newegg, you can even get it for 25% off using the promo code 25YRCELEBRATE.
