What adapter would I need to use with a seasonic s12 550w to get msi gtx980ti working

[bussjack2]

I have a seasonic s12 ss550ht and the psu comes with 2x6 pin pcie and 1x8 pin pcie available and the 980ti needs 2 8 pin connectors, what adapter would I need?

the 6+2 wires are 8 pin connectors but flexible. if you need 6 pins use the 6 pin and leave the 2 hanging. you need 8 pins use the 6+2, you need 2 x 8pin the 2 x 6+2 will do the job

Let me clarify, the psu has two six pin pcie connectors and one eight pin pcie connector, there is no 6+2 connectors on the psu

sorry my mistake, mis-read.
something like this maybe
https://www.amazon.com/Cable-Matters-2-Pack-6-Pin-Adapter/dp/B01DV1Z32Y/ref=sr_1_3?ie=UTF8&qid=1544134905&sr=8-3&keywords=6+pin+to+8+pin+adapter
example only not an endorsement shop around
I suggest getting a new PSU, the s12 is an older model and I'm not a fan of these adapters. this should be ok as the line is meant for PCIe power.
Never use a molex (4 pin hard drive) adapter to power a GPU

Thanks! I was thinking that would be the answer, wanted a second opinion.
