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

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).

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.

550W of fanless power from Enermax

Subject: Cases and Cooling | April 27, 2015 - 02:49 PM |
Tagged: Fanless PSU, enermax, Digifanless, 550W, modular psu, 80 Plus Platinum

The Enermax Digifanless 550W PSU is completely modular and as the name implies there is no fan to be found in this PSU.  Instead large heatsinks take up most of the room inside the casing, with a mix of Nippon Chemi-con, Enesol and DuraTech capacitors with the PFC and power components hidden under those heatsinks.  [H]ard|OCP's testing proved that the 80 PLUS Platinum rating that Enermax claims for this PSU is well deserved with efficiency over 90% in testing.  [H] was more than impressed with the overall build quality and performance of this heatsink, however the MSRP is significantly higher than the competitions which was why this PSU was left holding Silver.  It is not for sale yet here in North America so there is still a chance that a price reduction could make this PSU very attractive for those looking for a silent PC build.

"Enermax joins the ranks of the fanless computer power supply builders. These are of course a must-have for those enthusiasts looking for a zero noise profile computer build. Many times these sorts of builds of course suffer from very hot environments, so fanless PSUs are a perfect fit for our testing criteria."

Seasonic Snow Silent; if you prefer your PSU meek and pale

Subject: Cases and Cooling | March 23, 2015 - 02:30 PM |
Tagged: seasonic, snow series, modular psu, 1050W, 80 Plus Platinum

The ability to deliver stable power is the primary attribute we look for in a PSU but the aesthetics should not be ignored, especially for modders and those with glass cases.  The Seasonic Snow Silent Series 1050W PSU is aptly named for its white finish which gives it a unique look in a very crowed market but the exterior does not tell the whole story.  With a total of eight 6+2 PCIe plugs and a 12V rail capable of providing 1044W @ 87 amps this PSU will certainly handle Crossfire or SLI and it will do so fairly quietly.  TechPowerUp liked the 7 year warranty as well as the performance and look of this PSU, especially considering it is priced roughly the same as the bog standard grey model which does not have the improved fan of this model.

"Seasonic released a special version of their Platinum offering with 1050 W capacity; it comes with a while paint job and is equipped with an FDB fan and a relaxed fan profile for less noise output, which will thrill users looking for a quiet high-performance PSU."

Cougar CMD Digital Power Supplies Come With Integrated Fan Controller

Subject: Cases and Cooling | March 12, 2015 - 04:52 PM |
Tagged: power supply, modular psu, Cougar, 80+ bronze

Cougar is launching its new CMD Digital power supplies in 500W and 600W versions. In a move to differentiate itself from the crowd, Cougar has packed in an integrated fan controller and the ability to monitor and control the PSU (e.g. voltage) using software.

The new power supplies are modular excluding the main 24-pin ATX and CPU cables. Both models use a single 12V rail rated at 40A on the 500W model and 49A on the 600W PSU. Cougar uses a temperature controlled 140mm fan to keep the PSU cool. The CMD Digital is 80+ Bronze certified and features various over and under current and voltage protections (OCP, SCP, OVP, UVP, and OPP).

The following power cables and connectors are included:

  • 1 x 24-pin ATX
  • 3 x 4-pin Peripheral (Molex)
  • 5 x SATA (6 on the 600W model)
  • 2 x 8-pin PCI-E (6+2)
  • 1 x 8-pin CPU (4+4)
  • 2 x 3-pin Fan headers
  • 1 x TSR temp sensor port

In all, it’s a fairly standard layout with enough amperage and PCI-E power connectors to support a high end GPU setup.

The integrated fan controller drives up to two case fans (more if you use a splitters, I suppose) that are connected to the back of the power supply. Further, Cougar provides a temperature sensor that you can place anywhere inside your case to monitor case temperature. 

Cougar UIX Analysis.jpg

Using the company’s Cougar UIX software, users can monitor and control fan speeds, monitor system component utilization (CPU, HDD, etc), monitor power consumption, adjust voltage levels, and log various power delivery stats.

Cougar has not yet released pricing, but it will be available in April.

From the features, it sounds like a decent power supply though my opinion would heavily be influenced by the included software. Despite ample computing resources, I like to run a lean system with as little running in the background as possible. If Cougar UIX sips resources and it holds up to the advertised power delivery ratings, I would consider it.

Hopefully we can get one in for review soon and Lee can put it through its paces.

You are going to need 240V for this one; Superflower's 2000W PSU

Subject: General Tech | February 19, 2015 - 06:21 PM |
Tagged: kilowatt, modular psu, superflower, Leadex Platinum, 80 Plus Platinum, 8 pack edition, two freaking kilowatts

The perfectly reasonable 2 kilowatt Superflower is only able to provide a paltry 166.6 amps on its single +12v rail so you will need to be absolutely positive that your rig will not need a more powerful source of power.  Available only in the UK, it is possible that Superflower is not exaggerating when the claim it will accept 100V~240V, perhaps a budding North American electrician could set up a test to see if this 80 PLUS Platinum rated PSU can actually be powered by any mere wall wart.  No ones seems to mention the weight of this PSU but it does measure 150 x 86 x 220 mm which is a pity as this PSU would be perfect for an mATX build.  You can catch a video of this PSU in action on the last page of the review, powering a PC not an arc welder.

"‘Holy Moly’. This is the PG version of the first words I said when we were offered the new 2000 watt Superflower power supply for analysis. Renowned and highly respected UK overclocker Ian ’8Pack’ Parry partnered up with SuperFlower for the creation of this new monster unit. The ’8 Pack Edition’ is a fully modular design, 80 Plus Platinum certified and ships with enough cables to choke Godzilla."

Can the EVGA SuperNOVA 1300 G2 break the trend?

Subject: Cases and Cooling | January 9, 2015 - 03:26 PM |
Tagged: evga, supernova 1300, 80 Plus Gold, modular psu, kilowatt

[H]ard|OCP has not been impressed with EVGA's PSUs; they are not bad but do not tend to match the quality and pricing of the competition.  The new EVGA Supernova 1300 G2 is available for $180 and could buck this trend, it has a 10 year warranty, an 80 Plus Gold efficiency rating and it looks good on paper.  With the ability to provide a hair over 108 amps to its 12V line, eight 6 pin PCIe power connectors of which two can have the extra pair of plugs for 8 pin and solid performance it seems that EVGA has indeed produced a great power supply. [H]ard|OCP does not often award the Gold to PSUs but in this case thanks to the excellent build and power quality along with a very competitive price EVGA has produced a very good product for those who need serious power for their PC.

1417572920xIZRDi5XIp_2_8_l.jpg

"EVGA has a bit of a rocky road with HardOCP when it comes to PSU reviews. Today we give EVGA the opportunity to redeem itself with its 1300 watt powerhouse touting "exceptional efficiency" and a fully modular design that is "silent and optimized for the enthusiast." All this with a 10 year warranty? It must be a badass."
