What PSUs Are Compatible With A Q840av LB?


I tried a known booting 840 board (albeit with bad SWIM and SCSI), and it didn't show any signs of life, which is making me suspect a possible PSU problem.

I have a IIvx, a  Centris 650 and a Quadra 950. Would any of those of those work as a temporary stand-in for troubleshooting purposes? If not, what will? Does anybody have one they can loan out?
