I have recently got a new Ryzen Threadripper 1920x and a x399 Aorus Gaming 7 TR4 in a bundle. My current PSU is just a year old EVGAGQ 1000w and is working fine but I lost some of the cables and now I'm left with one 4pin CPU power connector. The Aorus Gaming 7 motherboard has one 4pin and one 8pin CPU power connectors. Currently it boots into bios/posts fine. But I'm wondering if I need to use the 8pin or not for the Threadripper. I am not really planning on overclocking the CPU btw. Thanks in advance.
