My PSU's just died so I need a new (or 2nd hand one). Up to now I've had 2 cheap EZ Cool 550W ones but they both only lasted 18mnths. I've got a P4 3ghz set up with 3 HDs 2 Optical drives and I'm about to buy a new gfx card that will also need a power supply. I'm looking at a 400w Enermax Liberty but would that be enough power??
