Well my 480W Thermaltake PSU emits a nice high pitch noise. Thats without the PC on. In fact it won't even turn on. So I guess its dead. So I need a new one. I would like a modular one and quiet. As for power usage, it is powering an Intel E6600, 4GB RAM and an ATI 4770. 1 SATA Hard drive and a DVDRW. So nothing fancy. However I would like it to cope should I go for an i7 build and a slightly better graphics, although I can't say I would opt for anything more than 'mid range' whatever that is at the time.
So fire away your suggestions.
