What is the series for that CM PSU? Yeah, don't bother investing in a PSU that has been used for mining.

Moved thread from Graphics Card to System's.

550w 80+ and 850W 80+ series

That's not enough information. What are the exact model names?

And if they're only 80+ White rated, they're not Cooler Masters I'd consider using to power even one GTX 1080, let alone two; there are no Cooler Masters I'm aware of with that low of an efficiency rating that are actually decent PSUs.

I'd also never run a heavily used power supply either. It's the PC equivalent of reusing hypodermic needles.
