Pros: It took five minutes to drop my failed supply and 5 more to bolt this one in. She lit on the first flip and is driving a 4 disk (1 TB per disk, SATA II) 0+1 array, 2 other SATA II devices, a liquid cooler for the CPU, 4870 X2 video, enough case fans to keep it all cool, a fan controller and everything else it takes to run a gaming system. Low heat, low noise, smooth power. Plenty of connectors for ANYTHING you might need.

Cons: Lots of cables but I expected that because I read before I buy. ...and yes, I have UPS because complaining about power stability without using one is like standing outside yelling at the rain to stop.
