Pc crashes when i play a higher end game

[DoSombras]

Every time i play a higher end game my pc just crashes in the middle of it ( around 10 mins into gameplay)
Its not overheating
I thought it was a faulty psu so i sended it to the store i bougth it for to test it and they told me its most likely a faulty cpu
They werent 100% sure so im here to ask if it can be anything else. ( they said it has a small chance of it being the mobo and a really low chance of being the gpu)
i recorded hw monitor while playing ( with my phone)
Here is a pic right before it shut off

My pc specs are
RX 7900 xtx
Ryzen 7 7700x
2 sticks of 5200 mghz ram ( fury )
a b650m ds3h gigabyte motherboard
some random 1tb ssd
and a hydro k pro 850W 80+ bronze psu
When it shuts off its unable to boot back up unless i turn the psu on and off.
And the blue ligth on the case does not turn off either when it crashes

as stated in your previous thread, that RX7900 XTX GPU states by the manufacturer that it needs a minimum of a 800w PSU.
and the website supplied by @Pyro suggests at least 950w.
so at 800w, you are skating close to the edge. then factor in maybe 20% of that 800w being lost in the conversion from the wall to the motherboard.
and yours in only Bronze rated, for such a high end GPU, Gold would be better.

see here for power efficiency explained: PC power supply ratings: 80 Plus Platinum vs Gold vs Bronze vs White | PCWorld

so while your PSU may not be the issue, if it was my rig, I would at least be starting there before moving on to other components.
and since your issues only occur on high end games, the educated guess would point to the PSU as the most likely contender.

As you were told in your last thread, and Bruce kindly reiterated- having an inadequate PSU is the biggest potential issue, I wouldn’t (quite frankly) waste your time chasing down other gremlins that may or may not exist until you can be certain that your components are receiving all of the power that they need.

Thread moved to the correct forum and because the junk PSU has still not been changed the thread will be closed,
