Question PC crashes and turns off with 3070 but not 750ti...HELP!!!

[cstorey987]

My PC crashes and turns off or short circuits when I try to play a game with my 3070 GPU. But I tried swapping in an old 750ti and it works without a problem. Could this be a PSU related problem? I had another PSU that burnt up and took an ssd with it, the new PSU is 80plus gold 850 w but its used. Im wondering if this is a PSU issue or if my 3070 is fried. I got COD Cold WAr to work on all low settings and dlss ultra performance. What do yall think???

Its a 850w 80plus gold rated psu. I took it out of another working system.

No, that's an advertised output and an efficiency rating. What's the PSU?

Its a Seasonic

Its a Seasonic

PC Part Picker lists Seasonic with 10 PSUs with this output and efficiency rating. Which model?

We're not even in the diagnostic part of this, this is just collecting the most basic information about the hardware. It would be a good idea to go ahead and list the rest of your exact specs as well.

The Nvidia 3xxx cards can have a momentary transient spike of power usage. All GPU's have this, but the 3xxx series have large spikes. If the PSU sees this, it can mistake it for a short, and automatically shuts the PSU down, crashing the system. PSU makers blame the GPU makers, and vice versa.

Would a better rated psu be a possible solution?

Would a better rated psu be a possible solution?

Best solution I could give is to get a higher rated PSU, somewhere between 900-1000 watt psu. It seems that they handle the spikes better.
