Hi everyone,


I've followed all the advice on how to safely set up PSUs and power your GPUs to ensure there's no fire hazard. However, I can't find definitive answers on a pretty simple question in ANY of the articles or videos.

I am running RTX 3080s, and they require THREE 8pin connectors from the PSU. The PSU supplied cables have 8-pin to dual 6+2 pin Y cable. As a result, two cables are needed to power a single GPU, and we have FOUR 6+2 pin cables from them. However, we only need 3 to power the GPU, so can the remaining 6+2 cable that dangles off to the side be used via a 6-pin female to 6+2 male extension to power a riser?

Thank you so much for clearing this up.
