actuallyit all just depends on the 5v rail some peeps might not have a prob (like me) i ran an [email protected] on a 200 watt MAX PS, generic also. and it was rock stable. But that was just shear luck also.
Id recommend a 300watt MINIMUM. I use a 300watt on my 1580mhz rig now and all is well but its still marginal in power im sure
Definately not. I am using a Antec 403 and am happy with it. It (and the 413) have the ability to adjust both the 3.3v and the 5v/12v lines. Present system is pushing 2.35v on the cpu and 250 is not going to do this.
I'm using a enhance 300 watter. can't go any higher than 1630 no matter how cool cpu is. If I raise my vcore past 1.85 forget about it. wont post except at default. my 5+ lines is 4.78. I think a 400w psu is in order.
