5 out of 5 eggsGreat Power Supply

Pros: The power supply works great. The wiring that comes with it is great also for most common computers. I didn't have any issue with power supply. I know it only has one year warranty but for paying $40 dollars its a good deal.

Cons: I did wish there would be another fan to flow from the back that it will be ok.

5 out of 5 eggsWorks

Pros: Works. Braided cables with a length working fine in a fairly large Zalman Z5 case. Was able to route cables behind the MB all the way to the top CPU 4 pin power connector.

Cons: None.

Other Thoughts: I can't speak for reliability as it's only been on for a couple days.
