I think 3070 and 5900 trigger OCP on my 850w power supply.

Long story short,
My GAME pc is working fine but cannot run GAMES because it instantly shut downs when I try to launch one. (ironic)
If anyone knows how to help me out that would be appreciated tremendousely.

Today I finished building my PC with the following specs:

MOBO: AORUS B550 Elite v2
CPU: 5900x
GPU: MSI 3070 Gaming X Trio
RAM: G.Skill Trident Z 3600 C16 4x8
PSU: Gigabyte GP-P850GM 850W PSU
AIO: Deepcool Castle 240 EX
HDD: 2TB WD black
SSD: Samsung 970 EVO PRO

The issue I run into is that when I launch any game, the PC immediately shuts down. Shut down without automatic restart, as if the power switch was flipped.
I have tested the following already:

Reinstall Windows,
Multiple BIOS flashes (F10 and F12)
Reseated Ram,
Run 2 instead of 4 sticks in A1 and B1
Updated Drivers for GPU (461.09)

DONE WITH THE SAME COMPONENTS:
Prime95 Benchmark (successful)
Kombustor Benchmark (successful)
TimeSpy Benchmark (successful)
CineBench Benchmark (successful)
Heaven Benchmark (fails 100% of the time on start Bench)

I have validated that there are no thermal issues using HWInfo (60 celcius on GPU and 65 on CPU).

The only issue I can think of is the Power Supply not being able to handle the spike from the 3070 when a game launches.
I already ordered a new PSU from Corsair (850RMx) to see if it fixes the issue but I might be missing something here. 

IMPORTANT: NORMAL USAGE OF THE PC SUCH AS BROWSING ETC IS NO PROBLEM AT ALL.

Pardon my English. Not a native speaker.

Yeah you aren't the first one to have a lot of issues with the gp series of psu's. So I wouldn't count it past it having issues.

Yes, good idea. 

 

The P850 is a really bad unit, Tier E if I'm not mistaken. 

 

The RM850x will definitely be better and will probably fix your issue.

Thanks for the feedback. We shall see then. I receive the new unit tomorrow so will update then for sure! I was not aware of the bad rating, instead I fully went for the overhead on power since the cards are known to need a large PSU... Boy was I wrong

The gp-p is not officially on the tier list I think but all does point to it being just a p series with gp added onto it so yeah tier e.

Always look into the psu's. The gigabyte does look promising but oh boi is it not at all a good psu.

Today I receive the 850RMx from Corsair. Will update when I installed it. If I can run Heaven benchmark without problems (shutdown within 2 seconds) I think the solution was indeed the PSU. Some advice on how to test the system for instabilities apart from those I tried before? Looks like those tested individual components but are not a representation of real gaming workload.

Fixed the issue! Thanks so much for assisting me troubleshooting.
The Gigabyte will be RMA'd.

Firestrike is pretty good imo... also well, actually playing games is a good test... 

 

 

I know the issue seems fixed, that's great (and expected) just saying.
