Recently upgraded to a GTX 1080 and now my PC will randomly shut down while gaming.

I've monitored my temps with HWMonitor and nothing goes above 60 ~ 65 degrees. This only started since I upgraded from my previous 760 to the 1080 and I've tried removing my overclock, messing with power settings, updating bios and drivers, and ending any extra processes running in the background. So far the only thing to really work is lowering the graphics settings, but at that point I'm not really upgrading from the 760. I built my PC in 2013 and the only changes I've made were the recent GPU upgrade and adding a 3rd hard drive for storage. My build is:

i5 4670k (now at stock speed)

Corsair HX 750 psu

EVGA GTX 1080 SC

16 GB DDR3 Corsair Vengeance

Asus Z87 Pro motherboard

OCZ Vertex 4 128-GB / Seagate 1TB 7200 rpm / Seagate Hybrid 2TB 7200 rpm

Hopefully someone will have an idea of what to try because I'm out of ideas now.

That's what I'm worried about, but unfortunately I don't really have one to borrow to test and I don't want to just buy one blind since it is a better brand/quality and it's only ~4 years old.
 


Only four years old? I'd swap out that power supply.

I was expecting to get a couple more years out of it since I sprung for the HX series /: I'll try to bribe a friend into letting me use theirs to test. I'll look into the warranty, I figured it'd be at least 5 years. Thanks for the help!

Just looked and Corsair's HX series have a 7 year warranty, so I'll try to track down someone with a PSU I could test with first, but it looks like I should be able to RMA. Thanks for the advice!
