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

This review is from: RAIDMAX Cobra RX-400AF-B 400W ATX 12V v2.3/EPS 12V SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Power Supply

Pros: Price. Got this Black Friday for $23 and change. Also came with a $10 rebate. This is my 3rd Raidmax Power Supply and never have had a problem with any one of them. The oldest being 5 years. Nice looking PS with Green non LED fan.

Cons: Not Modular but at this price point who cares.

Other Thoughts: Raidmax makes some real nice PS at a reasonable price. I don't see paying a lot more for a PS when Raidmax does just as good of job at a great price.

5 out of 5 eggsWorked great

This review is from: RAIDMAX Cobra RX-400AF-B 400W ATX 12V v2.3/EPS 12V SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Power Supply

Pros: Decent Design, not really loud, worked fine, had all the connections I needed for the PC repair. All around I think this is a nice PS. Connections all fit well,

Cons: None

Other Thoughts: was a replacement for an old power supply that died. This went on a Dualcore AMD processor system with 4gb memory and an older 8800GTS video card. All powered on fine with this one.

5 out of 5 eggsGreat PSU, easy to install

This review is from: RAIDMAX Cobra RX-400AF-B 400W ATX 12V v2.3/EPS 12V SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Power Supply

Pros: Easy Installation
Looks Fantastic
Plentiful amounts of connectors, especially Molex.
Cools down CPU very well.

Cons: None I can think of, other than the fact that the unused connectors can be a little bit in the way. Barely worth mentioning.

Other Thoughts: If you're looking for a good ATX power supply that has an ample amount of connectors and great energy efficiency, look no further. 400W may not be enough power for your rig, but it was for mine. The installation of it was easy. The cost was really low for the quality of it. Oh, and in comparison to my old PSU, this has already made a 2-3 degrees Celsius difference in the CPU temperature. Buy this!!!
