Troubleshoot this G3 PowerMac!

So, I bought my friend Tom a G3 PowerMac on eBay, which turned up, then booted to a blank screen. After a reboot, it started up, then the power supply went flash, bang and off. I've since connected my PC's power supply to the G3, tried the PRAM battery from my G5, and no luck. When the power button is pressed, the fans in the PSU twitch, and the lights on the motherboard come on, but then go out straight away. Is this a power supply compatiblity thing, or is the logic board fried?
