Recently my computer started locking up at various points. During games, random windows fails, on boot-up. I noticed that my power supply felt really warm. Just trying something random I unplugged my secondary hard drive thinking that if it had too much power drawn from the power supply that could be causing it to fail. Now my computer works great and the power supply runs cool. Do we think it is the hard drive or the power supply being under powered?

Its the PSU, CoolMax is just a generic PSU made of really bad and unreliable parts. Don't be shocked if it does blow up
I know these things are bad but I don't know how they can get away with putting them on the market.
Got one that came out of a client's dead machine ( I hate Saturday calls ).
400 watts, 27 amps claimed on the 12v doesn't sound to bad, but if the thing wieghs a full pound I'd be surprised.
All of the good PSU's do. Advantages: no voltage selector switch and therefore no expensive "Oops". Better than 80% efficiency - saves energy and reduces the amount of heat being generated in the case. Active PFC - that's kind of technical, but it is a good thing.
