3 out of 5 eggsGood Value

Pros: Cooler Master is a good brand, and I got a great price on this PSU. It works.

Cons: The cables aren't sleeved. That really bugs me, because they are a pain to work with and they look terrible.

5 out of 5 eggsGood Supply for the price

Pros: A good supply and I have had no problems with it so far. Runs really quiet which I like. I bought it mostly because it is cheap and the color is black to match my case.

Cons: None so far
