Question Gpu Upgrade for Windows 11

[abletudu]

I am thinking of upgrading from my 2 core GTX 960 to a GTX 970 which has 4 cores and 4x the Ram, but I need to change my PSU to one that has 2x 6 pin power connectors. I found a refurbished 970 on Ebay for about $60, but it requires 2x6 pin connectors and mine only has 1. Can you recommend one that would fill the bill? Thanks
