Nice brand, supplies what advertised. CPU power cable was a bit short though. Had to run ut up under the GPU and WiFi card

Before I get complaints about using a low quality PSU that will blow up my PC, I'll say one thing- it'senough. 360W on the 12V sounds pretty anemic, but according to PSU calculators and tests of a very similar system (860K, 270X) I would still have about 50W of headroom at full load. There's also the fact that it was $16 :)

2 years warranty instead of 3, full load calculated at 25 degrees (instead of 40 or 50), yet has 6 pins and 8 pins PCIe for your graphic card. 30 amps on 12v. Giving 4 stars for the features and because I'm happy today otherwise I'd give 3 stars because I had one to die within 2 weeks of use.

A cheap, yet reliable brand that I trust. Virtually silent!

Power supply was great but I could've went for 430 watts for$3 more but i wanted to save some money to buy better parts like a better GPU No regrets with this PSU though.

It's an O.K. PSU I don't like the look of the cables (Red,Yellow,Black) And I had a hard time getting them to reach the Plugs near the top of the mobo.

So far so good. Inexpensive and EVGA brand.

I do recommend spending the extra 5$ on the 430 watt version. Much better internals and cables are sleeved. The 400 watt also has short 24-pin connector. I only bought because I was limiting cost - I would not run this PSU at the rated capacity for long.

It does what's advertised, knocked off a star because no sleeved cables except for the 24 pin.
