PSU Voltages??

Hi All,

I have been having some probs with my PC shutting down recently. My issues were discussed in a previous thread and all fingers seem to point to the power supply.

I have downloaded Speedfan today and the voltages are listed below:

Vcore1 1.42V -12V: -8.99V
Vcore2 0.00V -5V: -8.78V
+3.3V: 3.28V +5V: 4.89V
+5V: 5.51V Vbat 3.04V
+12V: 12.54V

I have read that all voltages should be no more that +/- 10% or so. Which leaves me worried about the -12V and -5V.

I am replacing the PSU to a more higher wattage one anyway but it would be nice to know if my PSU was the cause of my problems.

Whats your thoughts?

I get different voltage readings from different software and don't rely on them. A PSU tester like click here is more reliable.

Hi Spartcus,

Took your advice and got voltages from multimeter.

As follows:

+3.3v = 3.34V

+5V = 5.16V

+12V = 11.91V

-12V = -11.18V

-5V = -4.7V

Can you see any problems there? +12v and -12V look a bit low?

I believe the -12V is not actually used.

Wait for someone more qualified than me to comment on the other readings.

And just Volts is no good on its own. Its no good if there is no amps to back it up. Thats what creates Watts
