Anybody can confirm the rx580 can be plugged with only one 8-pin connector ? I hope I could add a second one on a 520W power supply.
I have powercolor rx580 red dragon which has both 8pin + 6pin connector and I only use 8pin for each of them no problem works fine. I just need to improve my hash rate on SMOS.
Unless you are short in PCIe to power everything, is there a point using only the 8pin instead of both ?
