Hi, i'm on my way to buy RX 570 8GB sapphire nitro+ and since i have a pretty old PC, i only got 2x 6 pins for GPU. Problem i see is that the GPU has 1x 6pin plug in, and 1x 8pin plug in. Reason im asking is, is it possible and OR okay to use 2x 6 pins for GPU to work properly? There’d still be 2 pins left for the GPU. Will that worsen the performance of GPU? Id need a fast response, thanks.
