[SOLVED] Black Screen after 3-5 min gaming but my computer still runs

[Profesman213]

Hi everyone thanks for any help

I upgraded my Gtx 1060 to Rtx 3070 today. I am getting black screen when i try to play AAA games more than 2-3 minute but my pc components are still runing even fans gpu etc. but i need to force shut down to continue.

Here is some useful facts :

* Everything is fine when idle and everything is fine while i am playing basic games like Outlast or playing AAA games like RE8 with lower quality (1080p medium) but if i make settings 1080p or 4K very high i am getting black screen after 2-3 minute.

* I check my gpu's heat i got black screen when it is 75-76 degree but it is getting hot too fast (Like in 3 minute) . I didnt check cpu overheating.

* My suspicion is PSU. My psu is 600watt and not certificated and i think it isnt enough.

* Like i said when i got black screen every component of my pc still runs but no display.

So if it is about PSU or overheating how can i be sure or check it ?

I have 16gb ddr4 ram, i5 10400f and Msi b460m-a Pro.

Thanks

What is model name of the PSU ?
You can find model name printed on PSU label.
Photo of PSU label would be helpful.

That is 320W PSU (27 * 12 = 324W on 12V rail).
Obviously it can't handle RTX 3070.

You need 550W PSU minimum (46A on 12V rail).
If your RTX 3070 is factory overclocked model, then it might need up to 750W PSU.

Get rid of that garbage PSU.
And be happy, you didn't blow up your pc and didn't burn down your house by using such an inappropriate PSU for your system.

Thank you so much you are a life saver. I am trying to figure out for future possible problems. Are orange and red columns not important ? Because i presume you calculated yellow column.

On modern systems 12V rail provides power for cpu and gpu.
Other voltage rails are less important.
