Ok, so I've started building my new pc last week, everything was going good until i noticed that my psu has only 6 pin pci cable but my rx 570 requires 8 pin. I went on some forums to see if it is okay to connect only 6 pin until i get an adapter. I did that and the everything worked flawlessly. Today, my adapter came and i connected it. But when I try to power on the pc, the led lights of components just flash for a milisecond and thats it. It wont turn on, and now I have no idea what to do. Any help would be appreciated. (btw when I plug in only the 6 pin, everything works)
