TekSpek Guides

Power Supply units
Date Issued: 28th Apr 2020

Power-supply units, or PSUs, are an integral part of any computer build. Often overlooked, it is the component that is likely to last the longest, and it can be moved between systems when you upgrade to the latest and greatest in the future.

80 Plus certification
Date Issued: 18th Nov 2010

Conceived back in 2004 and brought to market just a year later, the 80 PLUS initiative is one of many standards introduced in an effort to increase energy efficiency in modern technology. Targeting computer power supplies, it awards PSUs that are able to achieve an energy efficiency of over 80 per cent at varying workloads and a power factor of 0.9 or more at 100 per cent load.

Green computing at home
Date Issued: 20th Nov 2008

This TekSpek explains what Green Computing is, what it means to the consumer, and how energy-efficient components can be beneficial in the home.

850W Corsair RMx Series RM850x, Full Modular, 80 PLUS Gold, SLI/CrossFire, Single Rail, 70.8A, 135mm Fan, ATX PSU is rated 4.8 out of 5 by 4.

Rated 5 out of 5 by Firefox1701 from Think twice if this is a D.I.Y. project As you'd expect, the unit does what it says on the tin. In the short time I've had it installed and for the minimal use the computer has had since then, there have been no issues with it. I bought this to replace a TW850X, and the only thing I would say is that unless you're already pretty clued up, I'd think twice before attempting to install it yourself. I consider myself to have probably slightly above what would be considered average knowledge of the inside of a computer, and I ended up calling someone else in to finish the job on the basis that I'd rather pay them now than after I've messed it up. The installation instructions that come with it are pretty basic, and if you're anything less than 100% sure what you're looking at when you open up the computer, may not be enough for you to do it yourself; in fact, ironically, if you were clued up enough to be able to do the installation from the instructions alone, you probably wouldn't need them in any case! Value-wise, at the time I bought this, for some reason, the prices of power units generally seemed to have been hiked up across the board. This was, arguably, one of the less-hiked-up ones, but in my humble opinion, still more expensive than it need have been, for what it is. Delivery, however, was very prompt.

Rated 5 out of 5 by Sligs from Does exactly what it was designed for I had terrible coil whine on my recently acquired RTX graphics card and someone on a forum stated it may be related to the power supply. I had my doubts but after extensive research this power supply provided the cleanest power. Sure enough, it cured the coil whine so anyone who is putting up with that awful noise should consider upgrading their power supply. Scan was awesome as always. Couldn’t be happier.
