Is it possible to hack an AT or ATX power supply to use it on a SparcServer5?

Hello, my SparcServer5 PSU just fried up this evening. It seemed to
work fine before, the light on the case lit after a bit and the fan
always started.
Is there some way to hack a normal PC power supply for it?
On the internet I didn't find any new power supply being made for the
SS5/20, and I don't want to use stocked stuff as my PSU, the damages
that they can cause when they broke can be very serious.
