Cooler Master V850 850W Power Supply Review

Cooler Master has been off our radar for a few years now as its power supplies were simply not up to snuff. Cooler Master's focus is back on enthusiast PSUs now with a lineup of new power supplies. The first one we are reviewing powers in at 850 watts, is a fully modular unit and it touts a host of high quality components and features.


Cooler Master Co. LTD. is a company that is well known for producing enthusiast computer cases and has been in business for almost 25 years. In addition to cases Cooler Master has product lines for CPU and GPU heatsinks, case fans, various accessories, and power supplies. Cooler Master’s entry into the power supply market has been rather mixed with some good products, and some that could use improvement. Today, we are reviewing one of Cooler Master’s new V-Series power supplies, the middle of the pack V850 which is produced in conjunction with Seasonic.

Seasonic is one of the older companies producing consumer power supplies having been founded in 1975 and entering the PC power supply production market in 1980. During that more than 30 years as a company Seasonic has cultivated lines of power supplies that are today some of the standard bearers for efficiency and quiet computing. This focus and Seasonic’s reputation for quality, has lead to a real explosion in production as Seasonic can be found providing OEM services on various model lines for Antec, Corsair, PC Power and Cooling, XFX, Cooler Master, and of course under its own Seasonic brand.

An 850W Phoenix?

The Cooler Master V850 is one of just a handful of Cooler Master power supplies we have seen over the years. The initial products we saw from Cooler Master were actually rather nice units. However, the most recent Cooler Master power supplies we have seen have been anything but good and as a whole Cooler Master went through a period where it was seemingly doing everything wrong with its power supply products.

Today, Cooler Master has for us a product that it feels will reset the clock to a better time with the V850. So, let’s see what Cooler Master has to say about this unit:

Cooler Master developed the V-series to re-ascertain its position as the worlds top power supply brand.

Based on a brand new platform, it features outstanding efficiency, especially at typical low idle loads, excellent hold up times, voltage stability and ripple suppression. It only uses highest grade Japanese capacitors, most of them solid capacitors, as well as a massive high quality 42mm transformer. And thanks to high quality FDB fans V-series PSUs are extremely cool and quiet. The V-series uses a fully modular cable system with beautiful all black, extra slim flat-ribbon cables. This makes cable management a breeze and results in nice looking clean builds with the best possible airflow.

Cooler Master certainly says a lot of nice things about these new V-Series units, but then again it has stated that about its products as well in the past few years.

Let’s move on and see what we can expect when a user purchases the Cooler Master V850 in terms of documentation, accessories, cable count, rail layout, output characteristics, and general build quality.
