The diode lights up (yellow) when you flip the switch. But turns red when I attempt to turn on a (particular) motherboard. Obviously this represents a fault with the motherboard. There's no mention of this diode whatsoever in the manual.

Given some of the less than stellar customer reviews for this PSU, I wouldn't be too quick to blame the motherboard - see some similar feedback re. the action of the status LED which was down to PSU failure. What's the units history / usage?
It's new. Works fine with other boards.
Just a thought, but is it possible that this PSU requires a minimum load to be present in order to work properly and the board you are testing with is not "hungry" enough ?

Do you have another psu to test your lga2011 boards ?
Right to repair is fundamental. You own it, you're allowed to fix it.

I have other psu's. I have 2 dig them out. I didn't want to have to disassemble a working pc to test these.
It's an interesting suggestion. Ve vill see.
I have a 4 cpu 2011 board that in "standard" operation has 2 1600 watt p/s'. I surely won't be needing that much, but extra juice never hurts. And running big supply at 50% is optimal efficiency, rigjt? Or should I ultimatlely just by some big server supply from somewhere?
?
for testing... I just use a simple psu 350/500W tops, nothing fancy, no fancy gpu either.
if it works, it works, if it doesn't, it's time to try different things.

The smallest I got is an Antec 430 watt. I have a p4/axp capable supply, some funky Rexxis name or whatever. That's maybe 400. Dunno. I'll try it with the Antec when I find it.
Oh what's a fancy gpu? IBM PGC? Got one. Don't think it will fit anyway 😀
I also have a Number9 Revolution. I didn't even know what it was for years. BYOD (bring your own drivers). Is that too fency-shmency? That won't fit either.

Great call. This apparently was the problem. All 4 worked. I was apprehensive about firing up the 4th board, a pin or two seemed questionable, but not so much from the angle I was looking at. So I said screw it. And all is fine.
Of course now the usb 3 issues will plague me. Maybe I can scrounge a cheap x1 pci-e card. Whatever.
Thanks for all the input.
