Dolphoos Posted March 12, 2019 Report Share Posted March 12, 2019 I have a Gigabyte x399 motherboard? it goes with 2 cpu power sockets 8 pin and 4pin. Madrid 850w PSU have only one 8 pin EPS (4+4) wire. I connected it to 8 pin socket on motherboard . Question is how to connect second 4pin CPU power socket? Additionally it has 2 red 8pin Pci-e sockets. Is the 8pin(6+2) pcie different fom 8pin(4+4) cpu (some psu models mark them like they are the same )? Can i use wire like that(photo attached), keys on the wire are the same, or do i need some molex to 4pin converter ? Iam a bit confused because of keys, is wiring the same or not?

TT0987 Posted March 13, 2019 Report Share Posted March 13, 2019 Hi There Thank you for contacting us. according to your problem I suggest you to get 8 pin PCIE to 8 pin CPU adapter, such as this one below: https://www.ebay.com/itm/SuperMicro-CBL-PWEX-0665-PCIe-8-pin-female-black-to-CPU-8-pin-female-white/362036775395?hash=item544b12c9e3:g:49IAAOSwEH9ZZp4T Of course you can get Molex to 4 pin PCIE adapter but since Molex's threshold is not as high as 8pin PCIE, I still recommend go for 8 pin PCIE to 8 pin CPU adapter. Finally, do not plug the PCIE cable to CPU directly! For this model, they have different pin assignment and you could damage your VGA card by doing so!
