It's been a few days since I put my build together, and I have begun to notice a relatively quiet, but noticeable high-pitched whine coming from the PSU after the computer is turned off.
The noise dwindles down after it is switched off at the back.
Is this a sign of a bad power supply, or am I just reading too much into it?
The power supply is an Antec TruePower 650w.
If any more information is needed, feel free to ask.
