[SOLVED] 650W to weak for rtx 3070

[sidekick99]

So i recently build a new pc (see specs below) and it would shut down when idling and playing games. During need for speed heat (gpu ~99% and cpu ~80% usage) my 650W PSU would draw 710W and evantually shut down.

I’m confused tbh because everyone suggests a 650W psu for my specs...

pc specs:
Ryzen 7 3700x @stock
RTX 3070 msi ventus 3x
2x 16GB 3200Mhz
1x m.2 500gb & 1sata ssd 1000gb
PSU: be quiet straight power 11 650W

how did you figure it draw 710w?

with an electricity usage monitor

Just my PC without the monitors.
CPU cooler: Noctua NH-U12S
RGB ram (corsair) 2 led strips controlled by NZXT controller

either your meter is wrong, or something is wrong with your system.

That wattage does not make sense unless that PSU is horribly inefficient or faulty.

I am running a 3700x with RTX3080 on a platinum 650w and under stress testing the whole system didn’t go over 546w at the wall. When gaming it goes up to about 430-450w.

Edit: I am also running PBO. The 650w recommendation NVidia gave was on a system running a 10900k if you read the small print. I expect it may be more a point about psu quality than wattage.

What could possibly be wrong with my system? everything works just fine untill it hits heavier loads and then it shuts down?

710w is wrong. unless you oc the gpu a lot

Everything is stock

Could it be that my psu is dying? it's 3 years old.
Would be sad because it wasn't a cheap one.

I would suggest no less than a 750W for a 3070 card. The transient spikes will cause most 650W PSUs to shut down.

What is the brand and EXACT model of your current PSU?

Seems logical, i ordered a corsair rm850x just a few minutes ago to replace my current one.

UPDATE: installed new PSU today (rm850x) and pc still shuts down in the same game...

Swapped out my 3070 with my old 1060 and no more crashes... should i rma my 3070?

Does your PC restart by itself after shutdown or it just stays off until you manually on it?
