8 Pcie cable has 1 "cutout"

[Scayron]

I'm building my first PC and came across this while trying to plug the power juice to my gpu: GPU is the msi rtx 3070 ti suprim x and requires two 8 pin pcie cables

 

But my psu came with 8 pin pcie cables with one cutout 

 

My psu is the deepcool dq750m v3l and it's 80plus gold (if that helps), and it has pcie slot requiring all the 8 pins (as it looks like)

 

Is this any problem.. ? Can I simply insert any side of the pcie cable to either the gpu and psu to make it work? If not then can I please get some suggestions. Thanks!

No. It has to be plugged in the correct way. The side of the cable that has a 6+2 connector is the side that plugs in to the graphics card. The other side which has the missing pin plugs in to the power supply.

It doesn't have text printed on the connectors saying "GPU" or "PSU" or anything like that?

No label for psu...The cables have labels like "pcie", "CPU", "ATX" 

 

So the side with the missing pin goes to the psu even though the psu slot has the pins..?  do those get no connection or something?

The PCIe cable has 3x12V pins. The row with 4 pins is ground. The socket on the PSU has a pin there because on the PSU the same socket is also used for the CPU cable which does have 4x12V wires. Since the PCIe cable only needs 3x12V wires the 4th terminal is empty.

Ah I see, so just insert the pcie cable portion with the missing pin into the psu and all's good, yeah?
