Cooler Master has launched a new series of power supplies aimed at gamers. The new Cooler Master GM Series is a line of 80 PLUS Bronze rated semi-modular PSUs that come in 450W, 550W, 650W, and 750W models.

The GM series feature a semi-modular design with a permanently attached ATX and CPU cable paired with modular ports for attaching the flat ribbon power cables with SATA, Molex, and PCI-E power connectors. The power supplies have a single 120mm cooling fan and a 3D circuit board that eliminates some internal cabling and improves cooling as a result (according to Cooler Master). The 80+ Bronze PSUs have a single 12V rail design that can deliver up to 62 amps on the 12V rail. They are also compatible with Haswell’s C6 and C7 sleep states.

The G750M, which is the 750W PSU, has the following connectors:

  • 1 x 24 pin ATX
  • 1 x 4+4 pin CPU
  • 4 x 6+2 pin PCI-E
  • 8 x SATA
  • 6 x Molex
  • 1 x Floppy power

More information on the new GM series can be found on the Cooler Master website. As is usually the case with product launches, exact pricing and availability in the US is still unknown.

Corsair's RM750 struggles to match the competition

Tagged: rm750, PSU, modular psu, corsair, 80 Plus Gold, 750w

As the picture below makes clear, the Corsair RM750 is a fully modular PSU which lets you pick and choose exactly what cables you want present in your system.  The single 12v rail is rated at 62.5A which should handle two fairly powerful GPUs, there are four 6+2 PCIe power connectors to do so.  This unit is rated 80 Plus Gold and it did live up to that rating in [H]ard|OCP's testing.  Unfortunately the efficiency and silent operation were the only things [H] was impressed by as this unit really struggled in their testing and even those tests where it could manage a passing grade the PSU lagged behind the competition.

"We have all read about Corsair power supplies and it is quite likely that many [H]'ers have one in their computer case right now. Today we are looking at Corsair's newest RM series power supply rated at 750 watts. The RM is built, "fully modular and optimized for silence and high efficiency." Let's see how it handles our grueling power tests."

Antec's High Current Pro 850W Platinum is worth its weight in ...

Subject: Memory | October 16, 2013 - 04:55 PM |
Tagged: antec, HCP-850 Platinum, modular psu, 80 Plus Platinum, Antec High Current Pro

If high efficiency is your preference then the Antec High Current Pro series is probably familiar to you.  Legit Reviews just reviewed their most powerful model, providing up to  850W and sporting four 40A 12V rails to power the six PCIe power connectors.  The fully modular design is great for keeping your case clean and the clear labellings on the PSU ensures you can properly balance the load between the 12V rails.  It performed admirably but the retail price of ~$200 did disappoint Legit Reviews somewhat.

"Today we will be having a close look at the 850W version of the High Current Pro series, the HCP-850. The HCP-850 is a modular power supply with a very long list of features and a seven year long warranty. As all of the High Current Pro products, the HCP-850 also comes with an 80Plus Platinum certification, the highest currently available on a retail product..."

Zeus loves tossing lightning bolts, SilverStone's new 1350W PSU

Subject: General Tech | September 16, 2013 - 03:36 PM |
Tagged: Zeus PSU, Silverstone, modular psu, 1350W

Way back in the early stages of this year Lee reviewed a PSU that not many would need but those who want multiple cards would appreciate, the SilverStone Zeus 1350W PSU.   The 12V lines, which is what GPUs care about are split into 6 with each able to provide 30A for a peak of 105A, 1260W delivered to your cards.  Unfortunately for SilverStone [H]ard|OCP have been working on this review since February and this final review is actually of the third unit that was sent to them as the initial PSUs had major problems. 

UPDATE: Tony from SilverStone reached out to explain the exact cause of the issue. 

"... it turned out that the circuit breaker he had wouldn’t play nice with ZM1350’s higher in-rush current.  Since power supplies are essentially analog devices, there are variances in production so the third unit apparently worked as ZM1350 was borderline tripping his breaker."

With the cause known you can decide on your own if your buildings curcuitry can support this PSU.

"SilverStone's Zeus series is back from a four year hiatus with a new 1350 watt PSU offering to enthusiasts. This Zeus is rated with Silver efficiency at 50°C, and comes to the alter with a host of features including modular cables to keep your build looking tidy. You can even tune the rails by hand if you wish. Time to see if heads roll."

Seasonic seems to be competing against its self with the X-Series

Subject: Cases and Cooling | August 27, 2013 - 03:56 PM |
Tagged: X-650, Seasonic X-Series, PSU, modular psu

Seasonic's X-650 PSU is fully modular, allowing you to choose exactly what cables you use though the ATX power is mandatory.  It has four 6+2 PCIe power connectors and can deliver 648W @ 54A to the 12V rail making this a solid choice for a multi-GPU system.  The performance on [H]ard|OCP's test bench was excellent, the only complaint they've had is that Seasonic really hasn't changed much about their PSUs in quite a while.  That might be a little boring for reviewers but for enthusiasts, great performance at a variety of wattage is a good thing.

H_1376852248OnesqnVojT_2_10_l.jpg

"Seasonic's X-Series computer power supply comes to us boasting a patented fully modular design that minimizes voltage drops and impedance while greatly maximizing efficiency, cooling, and overall performance. Being a Seasonic unit, we can also count on it targeting the users looking for a quiet computing experience."

NXZT's HALE90 series of PSUs is getting long in the teeth but still a contender

Subject: Cases and Cooling | August 12, 2013 - 03:36 PM |
Tagged: modular psu, PSU, NZXT HALE90, kilowatt, 80 Plus Gold

For $230 the NZXT HALE90 v2 1000W PSU needs to perform well to justify the price, especially as the 1200W model currently costs the same amount.  [H]ard|OCP has the tools to test this PSU to the limits and that is exactly what they did; the unit received a passing mark but no award as the quality of it's voltage regulation was right in the middle of the pack, no better nor worse than the competition.  It is a very efficient PSU if that is one of your prerequisites, it is rather attractive and offers a large selection of modular cabling.  Check out the full review for the exact specifications.

H-Hale90_1k.jpg

"The new NZXT HALE90 v2 1000 watt computer power supply has more than a few marketed points that talk it up like; clean currents, rock steady performance, eccentric design, and infused design elements. All that aside, we will put it through our brutal testing suite and find out if it is worth your hard earned cash."

Seasonic's high quality 400W PSU, the X-400FL Platinum

Subject: Cases and Cooling | July 17, 2013 - 04:48 PM |
Tagged: PSU, seasonic, X-400FL Platinum 400W, 80 Plus Platinum, modular psu

A 400W PSU seems a little under-powered when compared to the kilowatt PSUs that are commonly reviewed but there are not many systems that actually need that amount of power.  Seasonic has designed their X-400FL Platinum 400W to provide great power, efficiency and extra features in lieu of providing huge amounts of power.  The PSU is fully modular and is able to provide an impressive 33A combined from it's four 12V rails, with an absolute minimum of ripple even during the most intense parts of [H]ard|OCP's testingAt $120 it is a little more expensive than other similar PSUs but with the outstanding build quality of the PSU it is worth it.

"This new Seasonic PSU touts Platinum efficiency, a fully modular design, and a host of other enthusiast-worthy hardware features that will ring true with those looking for a what might be "the best" 400 watt PSU on the market. For those of you looking to build that truly powerful HTPC, this PSU also offers silent operation."

Computex 2013 concluded on a high note for Sea Sonic to lay the foundations for yet another highly successful year for our company. At the exhibition Seasonic has continued its tradition to introduce new models of power supplies that provide innovative and high performance solutions for a wide range of users.

During Computex 2013, we were proud to showcase our brand new Platinum 1200W power supply, which completes our premium Platinum series now extending from the 400FL Fanless to the 1200 watts top end unit. Many power users who are looking for this ultimate, fully modular model of top performance and reliability will appreciate the Platinum 1200W. This third generation, mighty power supply is built from high quality components, providing almost perfect DC-to-DC power conversion and will be equipped with our advanced hybrid silent fan control.

Seasonic has extended its popular M12II series by adding a new EVO edition in 750W and 850W models. These new models are fully modular and will be supplied with aesthetic flat black cables to facilitate customized cable management for any user. Due to the employment of higher quality components, the manufacturer’s guarantee of the M12II EVO Edition will be increased to 5 years.

Besides our current S12II series and our highly popular G series, we will launch a robust lineup of 80 PLUS Gold certified family of power supplies, consisting of 450W, 550W, 650W and 750W units. This new S12G series will feature less molex but an increased number of SATA connectors and will be entirely outfitted with flat black colored cables.

We have further extended our embedded power supply range for our growing number of industrial users and we are constantly looking out to boost cooperation with our business partners to create specialized industrial solutions.

Triathlor? Seriously Enermax?

Tagged: PSU, modular psu, enermax, TriAthlor, 650W

Platimax, Triathlor and NAXN; perhaps Enermax is not gifted at picking names for their PSUs but for the most part they are known for creating solid PSUs which do the job they are intended to.  Setting aside the name, this 650W mostly modular PSU has four 12V rails that combine to a peak of 54A, 648W which is certainly enough to power a modest multi-GPU system.  [H]ard|OCP put it through their own special brand of torture and were pleased with the results, a pass on all of their testing albeit results which trail the competitions offerings.  That keeps this PSU in the running as far as performance but at a current cost of $120 and perhaps higher in the future, it is hard to recommend this PSU over ones that do not cost as much and provide power of a quality at least equal to if not better than the Triathlor.

H_badname.png

"Today we bring you an "athletic" power supply from Enermax that weighs in at 650 watts. The new Triathlor series sports plenty of features that enthusiasts will like including Silent Cooling, Flexible Cable Management, is marketed as being Rock Stable at All Loads. Enermax ads that, "The Triathlor FC is not a blinky poser."

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

Subject: Cases and Cooling | April 15, 2013 - 06:54 PM |
Tagged: seasonic, Seasonic X-Series, 850W, PSU, modular psu

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.

H_X850.jpg

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?"
