One of my friends is badgering me to buy a Cougar PSU(I know nothing of the brand.), and I am afraid I might get another POS PSU.
Cougar does have some very good PSUs. But they also have some real stinkers. And the company is owned by HEC/Compucase which has a reputation for cutting corners. As an example, something in same general range you're looking is the Cougar A-Series 560 W Power Supply (Review)
