No dice - with CPU pulled board powers up and hangs with the CPU debug LED lit and error code '00', with CPU installed board powers up and hangs with error code '00' but CPU debug LED unlit. From this I'm thinking the mobo is at least functional enough to work out there's no CPU installed, but with CPU installed it can't even progress to first stage of POST.

The VRM can more than handle the full load XTU would have been generating at that point.
This is puzzling me a bit too - XTU testing at 4.5GHz at 1.3v should, to my mind, not have caused OCP to trip unless something's off. If I was pushing vCore 1.4+ or running IBT or equivalent then I could sort of understand it, but these were basically the settings AI Tuner suggested (with the exception of the uncore boost, dialled in manuallly) running the testing software Intel provides.
If the PSU is clicking off now I would not try to power up that rig any more...If you're getting 00 and the PSU is staying on then it could be dead CPU and not the other two. In these situations if one component in the chain fails, it can knock out all three.
Board is powering on and staying on, OCP not tripping any more, but machine is dead as a dodo stuck on '00'. No change using another PSU, sadly.
You'd be best advised to RMA all three items. If you are USA based send me a PM if you want to RMA directly with us.
In Australia Have applied for CPU RMA from retailer, which sucks as they're on the east coast, I'm on the west, and postage across the country takes about a week.
Have one guy on ROG that killed his 5960X while running 1.47 Vcore and 2.2VCCIN on chilled water. Not sure what he was running yet. Board was fine.
Fingers crossed my Deluxe will be OK then. RMA'ing that will be a gigantic pain given how bulky the box is.

Thanks for the input folks. Ideally I'd have another board or CPU to test with to narrow things down, but with what I have on hand I can't troubleshoot any further.
