Hi,
I have an AK77-600 Max with out of spec voltage rails. This mobo was recapped a while back. Both before and after the recap the 5v rail was pretty low but now things are quite bad. The pc hangs (especially when lots of high current drawing USB devices are attached such as ipod + wifi dongle).
Here are what the rails look like now:
Vcore(V): 1.62
+3.3V: 3.25
+5V: 4.73
+12V:12.43
-12V: -11.93
-5V: -5.79
5VSB(V): 4.80
Under high current draw 5v rail seems to experience a sag in voltage, sometimes to 4.70v and below. A number of symptoms are evident such as Ipod having difficulty charging. I replaced the 550w Xpower PSU with a Powwa 600W but the voltages on the rails is unchanged. How do I go about diagnosing this problem? I cannot accept 2 PSUs are identically bad.
Regards,
Achelon
