Usually yes.
Only problem really is that newer computers rely on 12V a lot, while good old retro-machines consume mostly 5V rail.
Therefore you need a strong 5V rail on your ATX PSU, which may lead you to buy something like 750W PSU just because it can push out enough amps on 5V...

Hm, I have one 450W in my 486 ATX tower. Works fine (with the ATX2AT smart converter). Indeed I need around 5A on the 5V and only 0.3A on 12V.
But I have one AT case where I don’t quite trust the supply and would love to have the security of the smart converter as well, since I play around with quite a few homebrew cards.

If you keep an eye on your 5V power rail requirements, go for it. Those old AT PSUs are not trustworthy anymore today. 😀
