I got the 3090 from evga and it came in today. I was expecting a pcie cable to come with it but it did not. I now need another 2x8 pin pcie connector that wont destroy my computer. The psu I have is " ROSEWILL PHOTON 1200W 80 PLUS GOLD FULL MODULAR POWER SUPPLY." Where can I buy a cable that is compatible with my psu? It has to be a 12 pin that plugs into the psu to 2x8 pin for whatever it plugs into, in this case being the graphics card.
