Hi all, interesting problem for you. This isn't a new build, rather one I did last December, but I have a recurring, annoying problem that I think this forum would be best placed to give advice on. First, the build:
Ryzen 5800X
Gigabyte 3090 Eagle OC
Asus ROG STRIX B550-F Gaming
2x16GB Corsair Vengeance LPX 3600MHz DDR4
BeQuiet Dark Power Pro P10 850W 80Plus Platinum
Win 10 Home 20H2
Valve Index VR headset
This is a good set of components and I'm very happy with its performance. However... in certain circumstances the machine hard powers off completely, like the power lead had just been yanked out. It's then completely dead (on/off switch does nothing) until I open it up, pull out the ATX power cable to the mobo and then reseat it. Only then will it restart, with no obvious ill effects. Googling around, this might be a way of draining the mobo capacitors and properly 'resetting' everything.
The hard power offs always occur when gaming, but only in certain games. I've had it in Doom 2016 and Subnautica BZ, but in random places. It happens more often in certain VR games and here it is reproducible - launching Google Earth VR will immediately cut the power as will starting a VR flight in MSFS (but not starting VR mode in the menus, that works fine, it's starting a flight that kills it). Most other VR games are fine - have played through Alyx multiple times with settings cranked up and not seen this once.
This sounds like a power delivery problem. My PSU is good quality, but is 850W sufficient for my GPU? It should be... Could it be a problem on the mobo? Would upgrading to a X570 with better power regulation help? The problem is I'm loathe to spend a whole bunch (more!) money replacing expensive components when I don't know what the problem is. What I find curious is that I can make this happen by firing up Google Earth VR from desktop. This tells me it's not heat related, as the CPU/GPU wouldn't have time to get hot. Also the power offs don't occur in demanding games (Cyberpunk 2077 runs in 4k with all raytracing on just fine) so it's not a problem with power availability, as everything can run at max power draw just fine for hours. The only thing I can think of is some kind of power surge that certain software conditions create which trips some safety switch somewhere. Or there is a weird fault with one of my components.
Would it help to run some kind of system logger and then engineer one of the power offs?
Thanks in advance for anyone who replies with advice!
