Question about PSU voltages

post #1 of 3
Thread Starter 
Im about to purchase a new PSU, and im wondering what do the voltages power. Such as the +3.3V, +5V, -12V, +5VSB. And what is the recommended amount to have on each? Thanks

well it largely depends on what you are planning to power with your system.

the main thing you need to worry about is the 12v rail. You want to have 18a at the least. about 32a should be good for your system.

While psus are rated by wattages, the amps are more important. on any psu on the market it will have enough power on the 5v and 3.3v rails. (they power memory, floppy, some hd...)

some good psu's for your system would be:
OCZ powerstream 520
Seasonic S12-500
Enermax liberity (not sure what model)
FSP somewhere in the 500w range
