Question Crash: Black screen and fans go to full speed

[Doltaro]

When I boot up certain games (including low demanding games) the screen goes off and the fans start spinning at full speed. The PC stays in this state until I manually shut it off by holding the power button. During this time, sound continues working (including communication such as via Discord).

I've been having this problem for a month now and it's driving me insane. It's a brand new system and the company who built it can't even find the problem, let alone fix it.

Event viewer shows absolutely nothing.

Reliability history shows the following hardware error:

It also shows that, during the time when the screen is black and the fans spin at full speed, the Desktop Windows Manager keeps crashing, about 6 times per minute.

Specs:

• ASUS ROG STRIX Z490-F GAMING
• Intel Core i5 10600K - 4,1Ghz
• Corsair Vengeance 32GB(3200Mhz)
• 1000GB SSD Crucial MX500
• 2000GB SSD Crucial MX500
• NVIDIA RTX 2060 SUPER 8GB
• Corsair CV650 PSU (650Watt)
• Windows 10 Home

Things I've tried:

• updated all drivers, including BIOS
• Reinstalled windows. Tried different versions. On 4 different hard drives.
• Replaced every single peripheral such as keyboard/mouse/screens
• Replaced the power cable.
• Checked all cables, made sure the GPU is properly attached.
• Checked temparatures of CPU and GPU; nothing out of the ordinary
• Checked voltage of the GPU, it spikes at 1.063v before the crash starts.

EDIT:
So I managed to get an old Geforce GTX 770 installed to check with another GPU and something weird came up. So my own GPU comes with an 8-pin PSU connection. However, the older GTX 770 comes with an 8 pin AND a 6 pin next to it. When I supplied it with 8 pins of power, it said to connect the proper PCIe cable at boot. I connected both the 8 and 6-pin to the old 770 and it worked, and it SEEMS there are no more crashes.

My question is, if this is truly the issue here, why on earth does my RTX 2060 only have an 8-pin PSU input, which might be too low? Is it normal? is it an oversight? How do I deal with it?

Well two things come to mind here. The first is that your GPU could be faulty and that looks like it could be the case. On the other hand, it could be the PSU is not delivering the proper voltage that your GPU needs to power. If it's the latter then I would try running your system with a stronger PSU like a Seasonic or a Corsair RM series to see if that is indeed the case. The CV is one of the lower tier PSUs in the Corsair product line. And the lower you go, the more it will cause problems.

I did check beforehand if the PSU was sufficiënt for the build. And the builders assured me it was. And that even a 550 watt would be enough.
Considering the build. is it very likely that the PSU is not powerful enough?
The RTX did show a voltage of 1.063v. Is that a normal voltage? A quick search says it's 1.050, not 1.060>, but that would indicate too much power, not insufficiënt.

EDIT: so I have two 8-pin plugs, and using either will create the same issue, while the old 770 has no issue getting to full 1.200v using both. Would this be enough indication that the problem lies with the GPU? I can't get SMI afterburner to avoid the crashes using either under- or overclocking.

Also, no matter how I run Furmark, I just can't recreate any issues.
