My computer (a Compaq) has a 250 watt Bestec power supply. I think it might be giving some incorrect voltages. SpeedFan gives the following: VCORE: 1.58v +3.3v: 3.31v +5v: 5.05v +12v: 11.25v -12v: 0.72v -5v: 5.11v +5VSB: 5.40v VBAT: 3.25v I think that I've seen the VCORE at 1.6 volts already; I'm not sure what it's supposed to be. I think the -12v has fluctuated between 0.8v and 0.64v or lower. The low voltage of the -12v has me concerned; maybe it's being reported incorrectly or something. I usually keep my case fan at 100%; but the RPM fluctuates depending on how high the -12v is. When that voltage is lower, the RPM is lower as well. Should I be replacing my PSU? It is a Bestec, after all; but I've had this computer since September of '05, with no power-related problems yet.
