I have recently pulled my 5160 xt out of storage, but the powersupple
seems to have given up on me, have anyone tried to repair one of those
before.
If its powered up with load the fan spins up , but there is a relay that
is tricked on a small vertial installed print, turning the whole thing
off.
The case of the powersupple is big enough that I could put a new
powersuple inside it with a bit for rewiring if it turns out to not be
repairable.

I think that the first task is to figure out if it's the power supply
or the load that's causing things to trip.
The 5160 PSU must be powered up with a load, or else the undercurrent
circuit will trip. Using a hard disk (any hard disk, not just the
one that came in the 5160) is a satisfactory load (with no
motherboard connected). If the PSU stays up, look toward a fault in
the motherboard or one of the associated components (expansion cards,
floppy drives). If the PSU with a small load still trips, look to
the capacitors in the PSU--very often, these are at fault and you may
as well replace them all.

Only trivial faults... But it's a _fairly_ conventional SMPSU, so it
shouldn't be too hard. I should have a hand-drawn schematic of the PSU in
my 5160.

I would be suprised if it's not repairable...
Given tht it died when in storage, I strongly suspect dried-up
capacitors, particularly on the output side of the PSU. If you have an ESR
meter, check them. If not, then either replace all the electrolytics, or
get an ESR meter (it's very useful for fixing PSUs and monitors!)
