PCI-E Cable in Peripheral slot

[GingerBill]

Hey all,

 

Building my new system and ran into a roadblock because i'm unsure.

 

I'm wondering if I would be able to put a PCI-E cable into the peripheral/Sata slot in my PSU.

 

For reference, my new GPU is an XFX 6700XT and my power supply is a Corsair RM750X. (See pic below and ignore the mess lol)

 

I am assuming it will be okay as the psu comes with 2 6+2 pin cables.

 

Any help on this would be greatly appreciated.

 

Thanks!

No, that would be liable to break something. Those peripheral slots have a significantly different pinout than the PCIe slots, and would therefore put the wrong voltage on the different wires. 

 

Remember, those PCIe 6+2 pin cables are directional, there's an end that has to connect to the PSU, and there's an end that has to connect to the GPU.

I don't understand why it would come with more than one pci-e cable then, surely if it comes with more than 1 then I am able to plug it in

It's because there are cards with 3 or more PCIe 8 pins on them. 

 

I.E.

The RX6700xt comes with 2 PCI-E ports on it. The cables I have split into 2 6+2 adapters, should I just use one cable and plug both in?

Yeah, that's fine. It's generally considered better practice to use both cables so there's less power going through a single cable, but in practice it doesn't matter that much for the lower power cards like the 6700 XT.

Hiya Mate,

 

Upon further inspection of the psu, it looks like I have 2x 4+4 cpu and 2x 6+2 pci-e.

 

As the peripheral and sata have only 6 slots, I assume that the others are actually for the gpu and i'm just being an idiot.

Thanks!

Yeah, all the 8 pin connectors on the PSU end should support the PCIe connectors.

Well i'm glad that has been clarified, major brain fart.

 

Thanks very much mate, it's very appreciated!
