Is it safe to plug the power cable like this into the GPU?

post #1 of 6
Thread Starter 


Yeah its a Gigabyte GTX 770 with 4 GB of vram. I was going to use the molex cables which came with the GPU but my PSU's molex cables couldn't reach them. So I just used a single PCIE power cable which had two PCIE connectors at the end. Is that safe or should I unplug one of them from the GPU and just use another PCIE cable? My PSU is a Seasonic X650.

Yeah its just that I'm worried it won't provide adequate power with just one PCIE cable.

My 670 FTW is connected using such a power cable, albeit with sleeved extension cables. I have been wonderingmmyself as to what if any effects it couldhave, as I gget massive ppower percentage spikes on occasion.
I am going to try to see if there's any difference at all using two completely separate PCI-E power cables, and I will try to report back anything I find.

i haven't done any official testing but i use two separate cables and my 670 ftw seems to always run fine.

the cables can handle the power, don't worry. the point where it necessitates the extra power plugs on the card is on the card itself - can't have too much raw current hitting the PCB at one point before it goes into the VRM.
