486 motherboards I have come across use and AT psu plug. How far back was this used - right back to ATs? Do 386 boards use AT plugged-psu's? What about 286's? I am guessing they might as the AT was an IBM 286 machine so presumably it's where the psu standard originated. But did the XT use the same PSU standard - ie. would an AT PSU work in an XT?

most 386's I've seen use AT PSU, and some 286 used those as well (got one 286 AT board lying around here somewhere) but most 286's were XT

Don't think the many clones were.

IBM 8088 boards have a differently shaped connector but the pinout is the same. I've replaced the connector with an AT one on such a board.
