Hi all, So in my system I have this PSU which is rated at 700W, but whenever I put a heavy load on it, I'm getting a 12 V rail reading of 11.3V and system instability (crashes)
I'm running a 8600K (stock) + 1080 + 1080Ti (both at 80% TDP) but when I stress all 3 together, my PC crashes in 10-30 minutes.
From my rough calculations, the whole system should only require 600-650 W at max (not counting the reduced power settings I've put on the video cards)
1080 = 186 W
1080 Ti = 267 W
Rest of the system = 150 W
Total = 600 W
I got this PSU as it received great reviews of Johnny Guru and being Titanium, I thought it'd handle 100% load well, but that doesn't seem to be the case
I only recently upgraded my CPU and motherboard and I wasn't getting this problem before with a heavily overclocked 2500K, so I am a little suspicious that it might also have something to do with the motherboard.
It only happens when I put stress on the CPU, but the temps are fine. When I put the TDP on the VGA cards up to 100% it trips my UPS alarm which is rated at 660W and as adding load on the cpu doesn't trip the alarm, I am pretty certain that I am below 700 W.
Apart from testing my PSU with a digital multi-meter, which is my next step, does anyone have any thoughts or ideas?
