Possible PSU replacement

[Amatsubu]

Hi,

My PC started randomly rebooting under load around two weeks ago (it also rebooted on YT once). Tried rolling back drivers, checking cables, cleaning etc. but to no avail. Power supply test in OCCT reboots the PC in a matter of seconds if I select use all logical cores. CPU test and GPU test run just fine separately. It looks like the PSU is on its way out but I can't exclude other possibilities until I disassemble my PC on the weekend to check it thoroughly. My PSU is a 3-year old Antec EDGE 750w. It's quite peculiar that it would go so soon but I've had around three power outages in recent months so maybe that somehow did it.

Just in case, if the PSU is the culprit:

Between the Corsair RM750x/i and EVGA G3, which would you recommend? The RM750x is supposedly quieter and I can have it slightly cheaper but the G3 is basically a SuperFlower and deemed to be a top-notch unit. Is the G3 noticeably noisy? I've read some complaints about it's predecessor getting somewhat loud over time.

Specs:

4790k
MSI 1070 Gaming X
Asus Z97-Pro
16gb RAM

Thanks for the help, guys

Yeah, I know I'm nowhere near the limit but I got a 750w unit in case I wanted to go SLI (the price diffefence was rather small back then). I probably won't though but you never know.

I might get something cheaper, I reckon 650w should be plenty for every single GPU setup considering components are getting less and less power-hungry? I run my card OC'd sometimes but on stock volts as it hardly makes any difference for a 1070. I will obviously be upgrading the GPU in the future and possibly the entire platform.
