4 out of 5 eggsDecent PSU for Price

Pros: Decent performance for price
Plenty of connectors
Suited well for bottom mounted cases
Quiet

Cons: Average looks, not meant to be seen

Other Thoughts: Put this in my sons new rig, didn't need anything fancy, just enough power to get the job done. No SLI or crazy watercooling, didn't even max out fans in case, just a few LEDs besides the basic components. Performance for the price is well worth it as long as your not looking for anything visually appealing. I was a little unimpressed with the way it looks, so luckily the case has a really small window so its not seen. It is quiet and haven't had any issues with it so far. The only reason I gave it 4 eggs was for the looks, they could have least taken the big spec sticker off the side, but it is what it is.

3 out of 5 eggsnever written a bad review

Pros: can't really call it doing what it should a pro

Cons: no complaints about the psu itself. it's doing what it should.
my issue is the rebate company coolmax uses is ridiculous! it was the most blatant "we're trying to make this difficult" rebate I've ever filed for. They all make stupid rules to keep from having to pay but coolmax needs to get rid of these guys. I may never buy another coolmax case or psu until I know I won't have to jump through so many moronic hoops for $20

Pros: Bought this Power Supply 11/19/2011 for a new system build.. This thing has been Rock Solid every since. It was bought for a Mid Range Gaming system that has been threw the torture test..

Cons: Not a dang thing.

4 out of 5 eggs

Pros: Runs a GTX 560Ti and a Phenom II x4 945 flawlessly.

Cons: First one had an audible whine and died after about 6 months. Pretty easy RMA though. New one works like a champ.

3 out of 5 eggsBad Performance

Pros: Works great Powered my powerhouse Core i7 1366 Socket 950 rig fine. Until I started playing a game and using my computer heavily.

Cons: Horrible on high load. PSU got very hot to touch in the back and started sputtering whine noises. Felt like I was reaching my power limit but I thought this was a 650 Watt PSU should of been enough. Was wrong, maybe it isn't. For a low- mid grade system this would of been fine. Forget high performance out of this PSU.

Other Thoughts: Bought a Cooler Master Silent Pro M2 RS720 instead. Hopefully it'll handle the powerhouse of Overclocked Core i7 CPUs.
