I recently bought a new psu a Corsair rm750e ATX 3.1. My question is how can I connect my rx 6700xt gpu to the psu and is it safe to connect it using the 12V-2X6 that comes with a 12pin pcie cable that splits into 2 8pin connector. My old psu comes with 2 standard 8pin connect but the Corsair only has 1 8pin connector and I need 2 to power my rx 6700xt. Thanks for your help.
