Im building atm on a X670E-E , ive noticed 2 Powerconnectors on the board.
Now my Gigabyte GP-UD1000GM PG5 V2.0 PSU comes with 1 cable , though it does split in 2.
Now the question is should i connect both ends in the 2 Power connectors? or do i need another seperate cable going from the PSU to the MB for the 2nd connector ?
Im using a 7800x3d in the cpu socket
You should have no problem to connect the single cable, in my opinion.
I am in somewhat similar situation on Asus X570-E motherboard although my second connector is 4-pin, not 8-pin, and they are connected on one cable. I have not encountered any problems with my 5900X CPU, which should consume more power than 7800 x3d when overclocked.
