Hi guys
I've stumbled upon your forum and I thought I would probably get some help from you. I'm a total noob in retrocomputing but felt the desire few weeks ago to play again with a PC of my childhood and recently start to gather some parts of it.

Here's the board I have: http://www.datasheets.pl/motherboards/MOTHERB … ARD_P55TP4N.pdf

My main issue (shame on me, really, I didn't thought I'd be blocked so early) is I can't figure out where the hell I'm suppose to plug the power switch connector (I don't have any case currently)! I remember years ago to boot my pcbs (> pentium 2) before mounting them in a case with a screwdriver where PW SWT was labelled on the pins, but here, I don't have any. And I do have a similar configuration with another dusty socket 5 mother board I own, no PWR SW indication…

I would like to avoid damages on my shiny Asus, so it be great if you could explain to me how to start the beast!

That board is a baby-AT board, it uses another type of PSU and the power switch is directly on the PSU instead of being triggered from the motherboard.

Your board uses an AT psu, so the power switch is on the PSU itself.
Here is an example picture:

you can get an AT->ATX psu adapter cable so you can use a modern psu but it will also have a switch like the photo above. The switch needs mounting on your AT-style case or rewired to the case's own switch . That's how things worked 😀

edit: 🤣, Tetrium beat me to it 🤣

Ho I see, thank you so much! I was using a ATX with ATX to AT adapter (no swith on it)while the AT psu I've orderer is on its way. I don't think that the AT psu I've ordered has a switch neither, so here a new item to find to be added on my list!

The AT HAS to have a switch...
In the meantime you can use a paper clip and short the green and a black wire by sticking it into the connector, that should power the PSU on
