Hello.
I built my machine a while ago, but hate my current cable management/look. It's an ITX build so the length of the cables makes good management impossible; I wanted to get a custom set of shorter, braided cables for my PSU. The custom set comes with one 8-pin PCI-E and one 6-pin PCI-E cable.
I have a 290, which needs both an 8 pin and 6 pin input. Currently, I have a cable that is split on one end to both an 8 and 6 pin connector, and I plug that in to the 8 pin PCI-E port on my PSU. I only have one labelled PCI-E port on my power supply, the rest of the empty slots are labelled as SATA and Peripheral.
My question is, could I use two separate cables; one an 8 pin to 8 pin cable plugged into the PCI-E slot on my PSU, and one 6 pin to 6 pin cable plugged into the Peripheral slot?
Here's a picture of the front of the PSU and here's my build spec.
On a side note, I just tested my power consumption under 100% load on all components and I was drawing a max of 390W; the PCPartPicker estimate was a very good estimate so props to them.
Thanks!
