Quick question, I have an EVGA 1000 GT I’m using for my build. I currently got a 5080, but plan on upgrading to 5090 when I can get my hands on one. The VGA cables on this split from one on the power supply to 2, if I have two of these, can they supply enough power for the RTX 5090?

 

Welcome to the EVGA Forum
 
I would highly recommend using seperate cables for each power connection to the 5080 GPU, even if using two cable works

System Power Supply:
· 850 W power rating minimum.
· Supported power connector configurations:
- At least three PCIe 8-pin cables
(with RTX 5080 PCIe Gen 5 Power Connector Adapter).
- One 450 W or greater PCIe Gen 5 Cable (16-pin)
 


5090 GPU = you must use seperate PCIe cable for the 600W load, each PCIe is rated 150W

- One 600 W or greater PCIe Gen 5 Cable (16-pin)
 
 
 

Appreciated! What I might do for now is use 4 cables, 2 of the normal VGA and 2 of the split ones and just plug all of them in temporarily. Appreciate the help!
