Okay so there are 3 sets of wires coming from the PSU to the mother board, there's 2 4pins (black and yellow wires) and a 1x6 (green and grey wires) connector that I'm not familiar with, I forgot to mention it's a prebuilt and I'll try to find the exact model, The 8pin in the the image between the 4pin and 1x6 connector goes from the motherboard to sata cords, the only other cords go to the fans and power button, I'll try to get a full image of the board
