This article says my Processor Takes 168 Watts on load, so that thus proves my power supply isnt big enough.
OK
So let's say that 168 watts is for the cpu alone and not the system.
And let's not bother with the fact that those numbers don't take psu efficiency into account and that the actual DC power would be 15-25% lower.
Let's go crazy and add 100 watts for the MB, ram HD and fans, all part of the Sytem Power consumption.
Now were up to 268 watts, running Prime.
An overclocked 450 pulls about 100 watts when stressed with Furmark.
Now we are at 368 watts, when stressing the psu with a couple of power viruses.
What makes you think a 550 watt psu wouldn't be capable of providing 368 watts ?
Maybe because it's a low quality psu ?
Ah, I should have hit the F5
