5 out of 5 eggsGreat Quiet Piece of Tech

Pros: Great power supply. Runs smoothly and gets the job done. For its price, I half expected a piece of junk, but what I got was nothing near that. When I first plugged it in, I thought it was broken due to how quiet it was. Would recommend to a friend.

Cons: The screw holes didn't line up with my case's. Not a big deal, nothing a little improvising can't fix.

5 out of 5 eggsGood quality

Pros: Good stable power, runs cool, very quiet, high quality materials. This is the first Cougar power supply that I have ever seen and so far I'm impressed. The main reason that I upgraded is I discovered that HTPC boxes with Happauge TV tuner cards will not pick up very many channels if the power supply is under-rated. After installing the new power supply I'm getting a large number of HD channels that could not be picked up with the old power supply. I'm getting premium digital TV that runs just as good as basic cable TV. I'm getting a strong signal from Seattle broadcast. I refuse to pay for over priced cable TV!

Cons: None

Other Thoughts: Your power supply can make a difference when you're running a HTPC video server with GForce graphics cards that are designed for gaming. I also upgraded my sound card to Soundblaster Audigy. My home entertainment TV box is a beast!

5 out of 5 eggsNice PSU

Pros: -Ease of Install
- virtually silent
- cable length
-120mm fan
- on sale

Cons: -only one meshed cable (picky I guess)

Other Thoughts: Bought for a new system build for my son. Looks great in his windowed case. I'm not very familiar with the "Cougar" band, but so far, I am impressed.
