    Apart from coil whine and caulk, I think a lot of people don't know what's that strange "click" noise that they hear every time they power on or power off the PC. Some think that it's some kind of defect.
    A guy told me that "if you hear that sound then the relay is defective, no relay makes noise" . I had to send him a voice message where I powered on three different PSUs with their relay noise. Of course there are noisier and quieter relays, but that guy was simply crazy.

    What are relays used for in power supplies? all mine are old and have none.

    I once tried to figure out how to make a transistor/relay hybrid, the idea being that the transistor and relay were in parallel, and so the transistor would do the switching so saving the relay contacts but not need a heat sink as the relay would carry the current; then it dawned on me that if the relay failed the transistor would burn out.
