I am searching a PSU for a client that still have a -5V pin in the ATX 24pin connector. Apparently his mobo need it to post.
Can anyone tell me why this particular pin have been removed and also, if you know any PSU that still have it?
no? no one?
-5v is a old ATX standard if I recall correctly which isn't found on modern psus cause it provided power for the ISA bus.
If you need a power supply that has -5 you'll need to dredge up an old 20 yr old PSU that most likely will not work on newer hardware.
You can find cheapo off-brand P4 compatible PSUs with -5v in some mom&pop PC shops.. at least where I live.
I seem to recall snipping the -5v on a couple because the Power Mac motherboards I was dinking with at the time did not need it. :P
i might have one in my computer graveyard i'll take a look for you if you'd like.
Since it's for the ISA controller it's impossible that the guy mobo need it. it's a 2-3 years old asus that wont power up and the guy is 100% sure it's the PSU and absolutly want that pin because he said it's for the power button...I'll just send him walk away...
