Power supply pin out

inavitech
inavitech 11 months ago

My company was discarding an old desk top and I removed the power supply from the tower, as I saw it could be useful for other projects and testing. Does anyone work on computers that can provide pin outs for P1 and P2? I know one of the functions is ON/OFF, since plugging it into the wall as is, I just get the green light momentarily and then it goes out.imageimageimageimageimage

    Hello what i found when setting a similar one up as a bench supply 

    was i needed to add caps to each rail.

    if running a audio amp it could have noises come through

    this mite say 12A ov 12v but it wont start up with that load already connected.

    and more than likely only uses the 5v rail for its internal regulation.

    Yes, there are great designs where the PSU is switching, and/or the power stage is class D

    switchers can be (and are) designed so that noise artifacts are outside the audio and sampling ranges.
