Hi, i have a Gigabyte A320 motherboard. A Radeon RX 580 GPU and a EVO LABS 500W PSU. The issue im having is that my GPU has a 8 pin power slot on it and my PSU comes with a 4 pin cable. Do i need to purchase an adapter? also my motherboard has a 8 pin 12v slot, again the PSU only has the ONE 4 pin cable. I'm very lost and confused. Can provide pictures upon request.
