This is my second Cooler Master power supply and both are working well. For the money I can't complain.

SOLID Performer
I bought this for personal build. As with most PC power supplies - easy to install. Well designed and built. Stable output and will not overheat. Just like an AK-47.

Exactly what I needed
My old power supply had a dying fan and was making sad, loud grinding noises. When I couldn't take it anymore I bought this one. MUCH QUIETER! Exactly what I needed. In fact, my wife keeps thinking the computer is off now because it's so quiet.

Nice Supply
Not a powerhouse but has good long leads, quiet, looks good in a black case, lots of hookups. I am a big fan of Cooler Master products, used them for years and never had a problem.
