Using an 8 pin instead of 6 for GPU???

[Spewky]

Hey there,

 

So I recently built my newest mini-itx PC using a Corsair SF450 powersupply. When wiring it all up using all the cables that were provided with the PSU, while I was plugging the wires into my GPU (an XFX RX5700XT) I came to realize that I didn't have a 6 pin cable for my GPU and that the power supply did not come with one whilst all other cables had already been used up. However, I still had an 8 pin cable. 

 

With the GPU, it has an 8pin socket as well as a 6 pin socket, however, given that I don't have a 6 pin cable but have a 6+2, is it okay for me to use the 6+2 8 pin connector without the +2 (if that makes sense). If not, I guess I'll have to go out and buy another cable. 

 

So yeah, I'd greatly appreciate any advice on this situation as I'd like to make sure I wont be doing any harm by doing so.

 

Thanks!

Just plug it in

the PCIE power plug is either 6 pin or 6+2 pin, if it's the latter you can just omit the +2 pin part and plug in the 6 pin cable.

The +2 is literally there so that it can be used as both 6 or 8......

An 8 pin PCIe power plug is literally a actually just a 6+2 PIN cable. The +2 provides some extra power, and isn't needed for a 6 pin plug. In other words, yes, you'll just plug in the 6 part of the 6+2 cable into your GPU, and leave the +2 dangling next to the 6, that is indeed how it works.
