So after getting my power supply replaced for new because it had power delivery problems, i plugged everything in yesterday, played for 8 hours no problem. Today i am playing for another 6 hours and in middle of a game my PC just turned off and wouldnt boot until i turned the power supply on and off. The leds on mobo were on tho. It cant really be overheating because i am using a kraken x62 in push/pull and during the game i play i get 37C. My gpu is at nice 57C too. Everything else that you can monitor in the programs never goes above 45C because of the airflow i created in the case with one extra intake and 3 exhaust fans. Any idea what the hell is going on? Cant really be the GPU because it was all fine and without problems. I also dont get any kind of error or warning, it just turned off. Never had this happen before.

Recently i went from i7 7700k that was overheating to ryzen 7 2700x with asus crosshair VII. Idk if i got faulty mobo/cpu or i am just cursed. Any help would be nice. Thank you in advance

Try the Prime95 and Heaven torture test i described running both for a while. Corsair LPX is all Samsung B Die, Corsair LPX LED is Hynix, I have it, but it works fine with Ryzen, that problem was corrected nearly a year ago and is nothing to worry about. CPU failures are ULTRA rare, failure rate is like 0.5%.

If it doesn't die from that it was probably a fluke.

My system clipped out once a few months ago gaming, despite passing that test. I turned it back on, kept playing, and never worried about it nor had the problem again. It happens.

Thats a good quality PSU and more than enough. It still in theory could be defective, but you already replaced it once. Theres 2 PCIe power ports on your GPU, you are using 2 separate power cables as per the setup instructions?

Yup always, I always plug 2 separate power cables that come with psu for these kind of gpus. The only weird thing i noticed is, that unless i make my GPU eat 120% more power (happened with old PSU too), it will only eat up to 250W and then voltage spikes from 980mV to 1063mV, BUT as soon as i let the power slider go to 120%, it eats up to 300W and the voltage stays at around 1050-1063mV depending on temps.

edit: the only thing i can say it fixed was my gpus loud coil whine. As soon as i got the replacement PSU, my coil whine almost vanished too, you cant hear it over the fans and it sounds a lot deeper than the usual high pitched coil whine.

Well so far it happened only once with the new PSU. On the old one, i sometimes had a hard freeze that only a hard reboot would fix. No blue screen or black screen, just my whole pc started to stutter and then froze. I still kind of get stutters. It happed with my spare 1080 too(its old one i have before i went to 1080ti for 1440p 144hz monitor). Tho i should have also mentioned i still do sometimes get tiny stutters, no matter if i use 1080 or 1080ti. So far i had 2 stutters, one yesterday and one today. I only upgraded like 2 weeks ago and had 0 problems with the i7 7700k apart from the horrible temps (87C with kraken x62 in torture, in witcher 3 up to 70C easy on 1.2V 4.7ghz) and that made me return it and change to r7 2700x.

As for the benchmark, it was the first thing i ran yesterday when i plugged my pc back together. I ran Timespy 3x, Timespy ex 2x and had no crashes or anything, FPS was same as always.

Not sure, my TV and lamp was on because my brother was watching netflix and nothing happened to that, just my pc suddenly turned off while a more gpu/cpu intense thing happened and again, wouldnt turn on unless i went back to psu and turned it off and then on.

I would keep trying and see how it goes before changing any parts.

For example I torture test my system and PSU by running Prime 95 small FTT and Uningine heaven benchmark at the same time. It will literally run everything at 100% and pull everything out of your PSU it can. If the PSU is gonna fail, or the system crash, that will do it.

Don't have heaven downloaded yet because since upgrading i didn't get to download it, but i have been thinking of doing it too asap. Have it run for a few hours and if it doesnt crash then it must have been just bad power in the house. If it does well... i am screwed and cursed. Since i know it can possibly happen with the 1080 and memtest returned with ram having 0 errors after 12 hours when i was testing OC on the ram since ryzen likes fast timings and was lucky and instead of my ram being hynix which most ppl get with this corsair LPX, i have samsung b-die. But ever since the first crash i had with old psu i put my timings to stock so it cant be that, and i rerun the memtest for another 6 hours and had 0 errors. So if its the mobo or cpu i am screwed, that is if it wasnt just electricity in the house being garbage.

Seems like it was just some weird thing with electricity in the hosue or something because i have been playing games since, even far cry 5 for 12 hours and didnt have the problem since. Man it had me scared because i thought my PC is breaking apart or smthing... My old pc started like that, turned off and all, month after the PSU died and took the motherboard with it and i5 4690k wasnt really working, turned out the onboard graphic chip is completely gone to hell and would crash my system, if i dont use it on that old machine it works just fine. It was a z97 asus maximus ranger VII and CX650M power supply.
