His PSU is dying. A replacement will cost about fiteen quid. Not replacing

instantaneous current, not time-averaged.
If you want to see a PC blow fuses, I've got one that will take out
anything it's attached to...

Change the PSU. Yesterday.

Ho yuss. I have a 1U box that flashes blue if you try to plug it in. Very
briefly, obviously...
