Usually my 12V is running at 11.71V consistantly(for months), but today I noticed that it was at 11.39V, and under load it goes to 11.21V. My 5V is at 4.87V, and my 3.3 is at 3.26V. Does a sudden drop in the voltage output indicate a failure is imminent? I checked voltages in pc probe II and with my multimeter. My power supply is a TAGAN 480W. At least the psu has a 3yr warranty... I haven't had a significant hardware changes recently(except a tv tuner, but it can't be drawing much). Any thoughts? Should I get a replacement psu ready?
