I connected the 6pins in front of the blue PCIe where the motherboard is plugged. I used the 8pins processor connector from the Enermax power supply for that. https://preview.ibb.co/gA1rHp/DSC_0036.jpg
I have to notice that the big 24pins ("MAIN" connector) from the power supply that goes usualy to the motherboard, can not be plugged in. So I don't understand how the motherboard could start when I power on the power supply... https://preview.ibb.co/eennq9/DSC_0040.jpg
