Question PC Crashing While Gaming

So recently I built my very 1st PC back in July. Here are my specs right off the bat.

Ryzen 7 3700x
Gigabyte GeForce RTX 2070 Super 8GB OC
ASUS B550-A Motherboard
G Skill 16 GB DDR4 RAM 3600mhz
Thermaltake Toughpower GF1 650 Watt PSU
Crucial 1TB M.2 SSD
Windows 10
2 intake fans and 2 exhaust fans (All 4 Artic F12) installed on HZXT H510 case

For the first month it was all running smooth. I never overclocked anything and kept it all at the factory settings. Coincidence but right before Flight Sim released I was playing Transport Fever 2 and the PC restarted on it's own. GPU fans kicked into ultra high speed for roughly 10 seconds and the PC restarted like normal. I figured it was the map file I was on and deleted it and it was fine then after. A couple days later went to play MFS and when it was 3/4 loaded I would have the same issue. Since then it happens more and more often, but not every time. I reinstalled Windows, updated the BIOS, updated the GPU drivers, pretty much anything I can find on the internet. I did download HWMonitor and would watch it while loading a game or running BENCHMARK and it seemed to restart when temps got to 60c. When I was able to use it normal temps never got over 64c as of yet. I have not tried MFS since reinstalling Windows (it's a huge download LOL). HWMonitor was giving me an indication that I would hit Reliable Voltage Limit and Operational Voltage Limit. I installed MSI Afterburner and Set the GPU usage to 105% allowable and even set the constant voltage and it worked great......for a week. Now I am having the same issues and I can't figure out if it is my PSU or my GPU. I have a RMA for both, but don't want to be wasting my time if it is a fixable issue.

BTW, my Event Log only tells me I get a Kernel-Power 41 task 63 error, which has been no help.

Can someone please help me?! I finally built my dream PC and I am so frustrated now. I can gladly post logs, just bear with me as I am not overly computer savvy. Thank you all in advance!!!

Increasingly frequent spontaneous restarts are usually caused by PSU outputs going out of specs and tripping protection circuitry either in the PSU itself or in other components like the motherboard or GPU. In the case of a fresh system, it could simply be that the PSU-GPU combination is not meant to be and you may need to get a different model of PSU or GPU to break out of whatever unstable condition they are running each other into.

Thank you. Do you think that wouldn't start happening after a month in of no issues? I do have an RMA for both PSU and GPU, just waiting on responses so I can send them. The Thermaltake guy said it wasn't an issue until I mentioned the Voltage Limits in HWMonitor. Maybe a bad component? Still odd it's not consistently happening. Thanks again.

Much like car engines and transmissions, electronic components have somewhat of a break-in period where wear may happen at an accelerated pace before settling down in a happier place. In the case of PSUs, most of that initial wear would be on electrolytic capacitors.

As for why this isn't 'consistently' happening, PSUs and VRMs need to be extremely stable under a very wide range of input-output transients. The conditions that trigger either of them to go out of wack if that is your case here may not necessarily line up easily.

A few years ago, there was someone on the forums who bought a bunch of new systems for his internet cafe and a few of those systems with Corsair AX PSUs and fairly high-end GPUs were randomly crashing. RMA'd the GPUs no dice, RMA'd the PSUs also no dice. Swap the PSUs for anything else, fixed. Swap the GPUs for anything else, also fixed. The GPUs and PSUs were working perfectly fine separately, just not together.

I don't see operational/safe voltage limit in HWInfo, so I have no idea what section you are pulling those from. Wherever it is from, it would be an indication that whatever is providing that voltage is getting borderline on specs.

Thank you, makes sense. I would rather update the PSU as it is cheaper than the GPU...lol You think it is worth going through the RMA on the the PSU or just get a new one? I guess I could always get a new one while the 650W is in the shop and sell it on eBay later. I just wonder how to know what is a better pairing? The 650W meets all of my needs of paper. Thanks again.

If you can borrow a completely different decent quality 600W-ish PSU, you should try that first. That would be the cheapest way of finding out whether I am correct in suspecting a bad PSU-GPU voltage regulator interaction.

Thank you. I will try and see if I can borrow one. Probably going to send it off regardless and see what they say. Thanks again, will keep this updated.

Never breaks 56c. Is there a monitoring program that logs info over a period of time, even with the shutdown. I have tried watching various stats but HWMonitor resets when the PC reboots. I can't view what was happening when it restarted.

Had MSI Afterburner open and noticed Voltage went from 1031mV to 1080mV but dropped to 1012mV right before the restart.

I downloaded and ran GPU-Z and can post the report, it is from roughly 20 seconds before crash. Also noticed that if I add up all of my wattage usage from report I get 631W and my PSU is only rated at 650W, should I invest in a 750W PSU?
