The power connector isn't compatible.
The power connector isn't compatible.
I recently received a 4080 SG from KFA2 along with a 3x8 pin power adapter. I'm trying to fit the cables marked "CPU" into the 3x8, but they don't seem to fit. I've connected two of the three available 8-pin connectors using the 6+2 connectors, but I still need one more. The only 8-pin power connectors included are labeled as CPU.
The cable for the CPU should be connected to the mainboard, usually near the CPU.
