Is a 650w 80+ Gold PSU enough for 3070 Ti & 5600x?

Hello,


After a long wait period, I decided to replace my old GTX 1070 with a new GPU. I was targeting an RX 6800 but it was not easy to find something in stock in my country.
In the end, I ordered a 3070 Ti. This is my current build at a high level:

  • AMD Ryzen 5 5600X
  • MSI MPG B550 GAMING EDGE WIFI ATX AM4
  • Corsair Vengeance RGB Pro 8 GB x 4
  • Samsung 750 EVO 250 GB
  • SanDisk SSD PLUS 480 GB
  • Seagate BarraCuda 1 TB 3.5" 7200 RPM
  • Corsair RM650x 650W 80+ Gold
  • NZXT Kraken X73
  • Fractal Meshify 2 (case)

My main concern is related to my PSU, as Nvidia recommends a 750W PSU for a 3070 Ti. I have already added all my parts to pcpartpicker in order to see the estimated power consumption of my build.
I could see that the estimation is at 523W.

Is my current PSU enough for the new 3070 Ti or should I consider a new PSU?

Thanks!

RM models from Corsair are good, techpowerup suggests 600W

 

you've got a pretty solid odds of the PSU being able to handle that..

Any questions?... Quote so I get a notification. In troubleshooting, I'm not always experienced.

Thanks for the comment. I could see that with factor of x1.2 my PSU could be enough. However, I have seen that some guides propose the factor x1.5, especially for the Nvidia GPUs.

I mean, kind of true, but that's mostly for lower quality PSUs,

 

if you want to be super sure find a high quality 750 W PSU instead,

 

but people seem to have no issues driving 3070 ti with a high quality 650W PSU.

Yes, the RM650x is a very good power supply, so this is why I was thinking to give it a try without buying a new one.

And if anything happens, then I will go for a 750w.

Don't go overclocking and you will be fine.

Thanks for the tip. I am not doing any overclocking and I am not willing to do it. Although, the card that I ordered is the Gigabyte GeForce RTX 3070 Ti 8GB GDDR6X OC. I have seen that generally, it will consume 310 watts, +20W than a founder's 3070 Ti.

oh yeah im sure ur good, i think the recommendations of higher W psus are just in case people if they buy trash psu it gets maybe overpowered by big wattage..
