UPDATE: It seems that it indeed was not a PSU issue, but instead my GPU dying. I have installed my new RTX 2600 yesterday and all has been well since then. Just like when I used my friend's GPU, I am able to play Divinity Original sin 2 for multiple hours in a row, without any sign of instability, let alone sudden shutdowns.
I like to thanks everybody that helped me solve this issue!
Also let's try to preserve shilka's
sanity and stop speculating if it was the PSU after all...
Two days ago my rig suddenly shut down (and restarted) when I was playing Divinity Original sin 2 (played the game for 60 hours the last 4 weeks without any issues). After the restart it gave me the following message: "Asus anti-surge was triggered to protect system from unstable power supply". Pressing f1 let me into the bios where I didn't change anything and it booted fine afterwards. I restarted the game and with 30 seconds after loading the save-game it again shut down
I have googled this issue and at least the error message (Asus anti-surge was triggered...) seems to be a common one (although I suspect different causes can trigger the same message). Below a list of stuff I have tried but didn't help (the first three seem to have helped others solve there issue where they get the same error message):
- turned off Asus anti-surge in the bios (turned it back on afterwards)
- reseated all cables, both a the PSU end as well as at the hardware end
- swapped the PSU (cooler master G450M) from second pc in (just connected the motherboard and gpu); note: this PSU is a lot less powerful, but should be able to run my primary rig, since it shouldn't use more than 400 watts when gaming
- load optimised defaults in bios (also removing the CPU overclock this way)
- ran AC: Origins just to check if this problem was specific to DOS 2; the same thing happened; also checked temps: the GPU was at 65C and the CPU cores at 38-43C when my rig shut down
- ran Unigen Valley on highest preset -> shutdown after ~30 seconds
- replaced power extension block with new one I had lying around
- connected PSU to different socket (also separately from monitors etc.)
- used different power cable (PSU to socket)
- used DDU to uninstall driver and install the latest one (430.64 WHQL) (long shot, but whatever)
- ran a video file for 10 min (MPC-HC with madVR to put on a ~50-70% GPU load); pc shut down within a couple of minutes
stuff that still works
- CPU stress test, x264 stress test 1 loop (takes about 10 minutes) with CPU overclock in place; no shutdown
- my rig has been idling a decent amount and no shut downs have occurred when not putting the GPU at 99% load
Note that the GPU is at 99% load when gaming (unless I hit 200 fps or unless there is a CPU bottleneck), since I use a G-sync screen with uncapped framerates.
So all this leads me to suspect that my GPU is malfunction/dying. Sadly I don't have a spare GPU around (second rig uses on-board graphics). I will ask a friend if I can borrow his GPU to test with.
Maybe you guys have anything else I could test or any theories to what might be causing this issue besides the "dying GPU theory".
