Very easy to set up

This 850 watt supply replaced a failed 350 watt power supply in my mid-sized tower. It was obviously a bit larger but it fit right in. I love the modular design. Use only the cables you need, and it is very quiet.

Good For Me

It is exactly what it says. Quite. And it has removable cords making it less cluster and bulk. I put this into a mid tower and I did find trouble with wire management because the case was smaller than expected but idk if its the case or the bulk of the main wires. It was my first build and if I had to guess I would say its the case. Overall great machine.

Great

So far so good. Rig has only been up and running for a week or so, but my case fans are the only thing I'm hearing and this power supply is doing its job. Also came with a lot of extra cables too.

Never hear a thing

It's got plenty of power, and plus since you bought one with over 850 watts, it's got plenty of power if you upgrade to a more demanding CPU, graphics card etc. Fan is silent, and you never, ever hear it. Also, the extra expandable slots are great to have, that way you don't have extra cords laying around in your case. Buy this!

Perfect

This is a good, reliable modular power supply that I have had running constantly for five months now, under somewhat adverse conditions (on a boat). I spent a bit more than I intended for this powrer supply, and I'm glad I did. I run dual video cards with a total of six hard drives and a water cooled processor rig with this power supply.

Worth every penny

Solid, quality-built PSU. All modular made it a breeze to hook up. Pick this sucker up; it's heavy! Silent; no gaudy LED lights. I would definitely recommend this to anyone who wants a quality power supply.
