5 out of 5 eggsGreat!

Pros: Really quite. The sleeved cables are nice. Its perfect for a simple setup. I have mine in a Lian Li PC-Q07 Mini ITX Case.
The fan is quiet and the unit does not get hot.
Price was great.

Cons: None.

Other Thoughts: I hope it lasts long but I think Raidmax is a good brand. This is my first time.

Pros: This PSU looks super sharp. Cables are wrapped in a mesh material that looks pretty good. Quiet. Didn't cost much. Works as a PSU should.

Cons: No issues so far.

4 out of 5 eggscheck rebate instructions

Pros: Seems to be working well so far. Nice green fan.

Cons: Rebate only gave 15 days to post mark. I've had plenty of items take at least that long. Power supply is nothing special.

Other Thoughts: The product is fine, but with those rebate terms, you know they're really trying to avoid paying.

5 out of 5 eggsRAIDMAX Cobra RX-400AF-B

Pros: Whisper quiet. It has all the connections I need. I love the green colored theme.

Cons: None, but it is a good sized PSU. It was pretty tight in my little case, but it fit. Not modular.

Other Thoughts: I bought this to replace my previous Hoover PSU. The sound difference is astounding. This was put in an old HP SR1701 case and it was a tight fit.
