I have one of the specified PSU driving a 2600K and two GTX1070s used for folding. The CPU is doing nothing much, the gpus are at full load.

Underclocked together by -100 MHz, both cards at full load and the overall machine works fine.

Either card overclocked by +100/600 (core/memory) is fine with the other card not running.

Both overclocked and running and the machine hard reboots.

PSU issue do you think?

Anyone had issues caused by sleeved cable extenders?

Maybe it's the combination of a crap PSU and extension cables bought from aliexpress. I've removed both the motherboard extension cables and the PCIE extensions and the machine is again seemingly stable with the cards overclocked.

I will look for a better PSU though.

They have been known to cause issues before, have you tried without them fitted

just removed them and the machine is better for sure.

I don't really understand why these extension cables are all so long. On a 24-pin you see maybe four inches, on the 8-pin maybe two, on a PCIE cable maybe six. Yet they seem to be around 18 inches.

By the way, computer "folding-stable" with overclocked gpus for 13 hours now. Only change is those extension cables.
