gtx1080sli pcie help

Hey all

My rig has 2x MSI gtx1080's in sli and I want to replace the ugly pcie cables it came with.

For example take the 1st card the msi gpu has an 8pin and 6pin connection and obviously both must be powered, But on my rig its only being powered by a single 8pin cable that splits into two 6+2 that plug into the gpu with the extra 2 pins just dangling.

So is this necessary? my PCU has spare 6 pin connections could I just buy an 8pin cable and 6pin cable separately and plug it into the gpu instead of this single 8 pin that splits into 2 8pins?

Does this setup limit the power my gpu receives?

You shouldnt use the included adapters if your PSU has the nessecary pci-e connections directly.

Yes you can get cables that convert 6pin to 8 pin.

What PSU do you have?

looking at the PSU I can see 2 spare 6pin connections. could I remove the (8pin split to x2 6+2) from the GPU's and just run the needed 8pin and 6pin as separate cables?

Yeah running them as separate cables would be the best option.
