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."

Cooler Master Launches V Series PSUs

Subject: Cases and Cooling | September 19, 2015 - 06:08 PM |
Tagged: cooler master, PSU

Cooler Master has "announced the availability of" six power supplies in their “V” series. They are high efficiency products that are fully modular with flat cables for routing. They each use “100% high quality Japanese capacitors” and introduce “exclusive 3D Circuit Design”. Models are available in 550W, 650W, 750W, 850W, 1000W, and 1200W. The highest-end one was announced a while ago, back in 2014, but the line is now available and larger.


The V550, V650, V750, V850, and V1000 each carry an 80PLUS Gold certification for efficiency, while the V1200 is rated at 80PLUS Platinum. Cooler Master claims that their 3D technology, which uses full, separate circuit boards to distance noisy circuits from each other, provides three benefits. First, it reduces heat and improves heat dissipation. Second, it reduces inefficiency that could be introduced by signal noise, which sounds a bit weird for direct current but makes a bit of sense. Third, the reduced ripple and noise can lower long-term stress on the capacitors, which definitely does make sense to me.

Five of the six power supplies come with five-year warranties (the 1200W has a seven-year one). They are available now and range from around 90$ USD to around 300$ USD. The V1200 is currently 30$ off at 270$ USD on Amazon.

One day the Enermax ZDPMS might tell you just how good your PSU is

Tagged: enermax, Zero Delay Power Monitoring System, ZDPMS, PSU

On its face the Enermax ZDPMS software seems a brilliant idea, giving you detailed real time information on your PSU and what it is currently doing.  You can watch each rail separately with values for both current and voltage being displayed, the overall draw on your PSU and its current efficiency rating as well as setting Over Current Protection values.   There are some flies in the ointment, not the least of which is that as of this moment the software supports the Enermax Digifanless 550W PSU ...and that is the end of the current list of supported models.  The current version of the software also let [H]ard|OCP set OCP and OVP values at which the PSU should trip an alarm and reduce or shut off power, which was not exactly what happened when [H] tried an admittedly nasty trick on the PSU.  The review is not all negative and there are some hints of what this software could aspire to as it matures, you should read the whole review right here.


"One area that has been somewhat overlooked when it comes to PC desktop system power supplies is monitoring software. There have been some attempts in the past, but those have been somewhat anemic. Enermax is looking to change that with its new Zero Delay Power Monitoring System."

HDPLEX Creates Fanless, Internal PSU for NUC and Thin-ITX

Subject: Cases and Cooling | September 8, 2015 - 07:00 AM |
Tagged: PSU, nuc, Intel, HDPLEX, Fanless PSU

In an effort to make small form factor PCs even smaller, HDPLEX has created an internal power supply for them. Added benefit: it's fanless and supports up to 80W. This is designed to replace the power bricks that are apparently common for most builds, meaning that you have one less thing to hide behind something else.


The unit takes up 121.5mm x 30mm x 40mm, which works out to 4.8”, 1.2”, and 1.6” for people who like measurement systems without simple decimal shift conversions. This is on par with some external power bricks that I've seen for the NUCs, although those are 65W (the same as Intel's official brick) while this one is 80W. I'm not sure what that extra 15W will get you though, unless you jump into the Thin-ITX form factor, which is also supported.


The HDPLEX Nano ACDC 80W is available now for $32 USD at their website and Amazon.

Thanks FanlessTech.

Existing Corsair Water Coolers Support (At Least) Skylake

Skylake is coming up, with rumors pointing to a release at Gamescom in Germany, which is August 5th through August 9th. Beyond seeing the retail packaging, we are beginning to see to companies open up about how their products relate to the new architecture and chipset.

Corsair put up a blog post a few days ago to explain how their memory, water coolers, and power supplies interact with Skylake and Z170. On the PSU side, nothing has changed since Haswell. In terms for memory, DDR3L is supported with Skylake under certain motherboards, but users should look to DDR4.

None of the above should be new information.


What might be new information, though, is that Skylake supports existing LGA-1150 cooler mounts. This means that the Corsair Hydro series of sealed CPU liquid coolers will support Skylake without modification. This is where Corsair's blog stops but, knowing Intel's typical release structure, this likely means that the story will not change for Kaby Lake or Cannonlake, either. These three architectures are expected to use the same socket, which should mean the cooler is the same too.

So your aftermarket cooler should have quite a bit of legs, even with the stock mounts.

Corsair has shown its first SFX form-factor PSU at Computex, the SF600.


Image credit: Tom's Hardware

True to its name the SF600 is a 600W PSU, and it features a fully modular design and will carry an 80 PLUS Gold certification. According to the report from Tom's Harware Corsair is using a 92 mm fan with the SF600, slightly larger than the 80 mm fans found in standard SFX power supplies, but smaller than the 120 mm fans that SilverStone has been using in its SFX-L form-factor PSUs.

Will a 1000W SilverStone PSU get the 7 year itch?

Subject: Cases and Cooling | March 10, 2015 - 01:42 PM |
Tagged: PSU, Silverstone, olympia 1000W, kilowatt, endurance

Seven years ago [H]ard|OCP reviewed a SilverStone Olympia 1000W PSU and it has seen regular usage since then, which lead them to wonder if there have been any changes now that the PSU is four years past warranty.  The testing did reveal certain changes of which the most troubling was the PSUs inability to finish the full load test at 100 or 120v .  When tested at 750W the PSU had no issues and while the voltage regulation was not quite as tight as it was it is still impressively stable for a PSU of this age.  Power output has also suffered, with an increase in noise, enough to take it out of specification and the PSU was also louder than it was way back then.  Take a read through this article for an idea how this particular PSUs performance has changed over time.


"Many people ask about long term computer power supply testing, and simple truth is that it is too expensive for HardOCP to do in-house as it would require hundreds of thousands of dollars' worth of resources. However, we can give the inquisitive a non-scientific look at how well a personal PSU does in our testing 7 years later."

Fractal Design and Seasonic team up with Edison M series of PSUs

Subject: Cases and Cooling | February 3, 2015 - 04:30 PM |
Tagged: fractal design, edison m series, PSU, 650W, 80 Plus Gold

Fractal Design's 650W EDISON M Series semi-modular PSU has a bit of an interesting mix of features for a 650W PSU which drive the price up somewhat.  TechPowerUp puts it's MSRP at $105 which is a bit pricey for a 650W PSU which is not totally modular but with an 80 PLUS Gold rating and a 5 year warranty the price is somewhat justified.  The single 12V rail is capable of providing up to 54A to the six 6+2 PCIe power connectors, giving you some ability to power dual GPUs.  In the end, it proved to be a solid performer but the decision to sacrifice a second EPS connector for the additional PCIe plugs and the pricing prevented it from winning an award.  It is still work checking out if you do not need a second EPS plug.


"Fractal Design has for the first time worked with Seasonic, and the outcome is the Edison Modular series. Today, we will take a detailed look at the Edison M with 650 W capacity, the second-strongest unit of the series. It features Gold-certified efficiency, a semi-modular cabling design, and an FDB fan."
