Possible to re-use an original IBM XT PSU with a newer 486 baby at mobo?

I found an empty IBM XT 5160 case at the local recycling center, said I could have it. It's in good shape except for a few patches of rust that can be sanded off. I luckily was able to find and purchase a working IBM XT power supply off of Ebay and I am now left with a question. The IBM PC XT computers were made before the "Baby AT" standard came about, but appear to have the same P-type mobo connectors. I found that normal sized baby at motherboards have trouble fitting in this case, but I also happen to have a compact 486 mobo - the FIC 486-J, and it appears appears to match the standoff mounts:

Will this mobo be compatible with the older XT power supply, or should I look for a replacement 8088 or 286 mobo? Thanks for any help in this.

An IBM PC or XT power supply and a generic AT power supply have an almost identical pinout. The only difference is that the P8 Pin 2 is a Key (not connected) on the XT and +5v on the AT. I don't think it really makes any difference in practice, the physical form factor of the XT power supply is usually a larger obstacle.

You should be able to do it, as long as you don't overload it. Remember it's only around 130W or so.
