Given that I'm on holiday at the moment and am restricted to house jobs, I've been trying to troubleshoot my Indigo2.

In short, it runs for a while, then powers off. I've had issues like this on and off for ages with it, bought another PSU from Ian a few years back and initially thought the problem was gone, yet with prolonged running, it kicks in again. Also had one of my PSUs sent off to a repair firm who completely re-capped it and replaced 4 resistors as well, but I still have issues. So I've tried a number of combinations over the past few days:

PSU No. 1 (original internal components):

All main components installed (Max IMPACT, hard drives, etc): 28 minutes runtime before powering down.
Graphics card swapped with SolidIMPACT: 1hr 54 mins runtime before powering down.
No graphics card or hard drives (system chimes, then sits there): 6hr 30 mins and still going.

PSU No. 2 (re-capped PSU):

All main components installed (Max IMPACT, hard drives, etc): 57 minutes runtime before powering down.
Graphics card swapped with SolidIMPACT: 4hr 6 mins runtime before powering down.
No graphics card or hard drives (system chimes, then sits there): 6hr 30 mins+ and still going.

Should note I also swapped the fans back to the original Panaflow ones just to ensure poor cooling wasn't an issue. This had no major effect on timings, in fact it actually ran slightly longer with the un-modded PSU and quiet fans than it did when I swapped the Panaflow one into the card bay. All tests were run with the case fitted to ensure cooling would be effective.

So! Power draw definitely looks to affect things, and with lower power draw it does run longer before crapping out. Plus the re-capped supply does seem to survive longer before the system dies. However I'm still not fully sure what is causing the issues. Do I have two duff PSUs (possible due to the age of them)? Or is it possible that there's something else at fault which is possibly putting too much strain on the PSU until (presumably) the PSU's protection circuits kill the thing. Any ideas on how I can try to suss this finicky bugger out would be welcome at this stage!
