Hi guys I'm trying to spec my friend a cheap upgrade and he only wants to spend about £50 on a PSU but needs to be as silent as possible. It will need to run a P4 3.2, 8800GT 512MB, 500GB F1. I thought maybe one of these but open to your wise suggestions, modular is a bonus but not essential, silent running is most important factor:
OCZ StealthXStream 500W
Corsair VX 450W
Akasa Ultra Quiet 500W Paxpower Active
Gigabyte ODIN PRO 550W
Thermaltake ToughPower 500W
Also is the 8800GT backwards compatible to PCIe 1.0 and will there be much of a performance hit?
TIA
