Is 850W Gold PSU good enough for EVGA 3080TI and Ryzen 9 5900x?

[JingleJaxson]

I'm getting the EVGA 3080 TI FTW3 Ultra and have a Ryzen 9 5900x CPU. Is an 850w Gold PSU enough for this? Below is the one I've got:

It's a garbage ACRF PSU, but if you already own it....  Best thing to do is torture test it with Prime95 (small FFT torture test) and Furmark at 1080p with 2x MSAA running at the same time and see if the PC reboots.

 

Also, don't forget to play som New World to see if the graphics card burst into flames.

You... do realise there is more to a PSU than just the wattage...?

[Downkey]

Wattage wise it's certainly enough, but overall I would advise against using it as it's a pretty mediocre unit. Wattage and efficiency aren't everything.

Any recommendations for a PSU? I'll use it for now but upgrade next week (hopefully).

I just ran furmark 1440p. Installed this card last night.

That's the scale, judging by the graph, the maximum power draw was about 550-600W.

It's not the scale, it's the peak output.
