Powering 2 GPUs

using 2 dedicated PSU cables is recommended since you may lose a bit of performance. Personally I use 1 psu PCIE cable for 1 card then if I have 2 cards then I use 2 cables. Using the same cable on both cards should make it "work" but you may not get the max performance.

 

Jay has a pretty good video showing it in action:

 

Hope this helps :)

 

BTW I'm not saying it wont work, most likely it will work just fine its just you may loose a few MHZ here and their but since ur PSU sounds good you should be fine

So I recently built my computer and saw that some builds use 2 cables (rails?) from the PSU to power their graphics cards, and I was worried if my system would need me to do the same? I have a 2070 and a 1060 3GB both on 1 cable. Should I add another cable? P.S., I'm powering the 2 using a 850W power supply if that helps. Thanks.

you are probably fine. those gpus take around 300-w when on 100% stress i believe. Can you take a pic of your psu? or what psu you have?

I Use my knowledge as business owner and self taught technician aswell as an AI to help people. AI might be controversial but it actually works pretty well 90% of the time.
