Is my power supply going bad? Voltage Drop

  1. 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?

    I think your psu may well be failing. Those voltage drops aren`t a good sign.

    I suggest you rma it ASAP.
