Graphics card power connectors

[Hypermale]

I'm thinking of upgrading my graphics card. I currently have a VTX3D Radeon R9 390, which is powered buy 1x 8-pin PCIe and 1x 6-pin PCIe power cables from my Corsair 750W CS Series PSU. I am considering buying a Radeon 5700 XT but I notice the cards have different power connectors depending on the manufacturer and model. Some have the same as my current card, and some require 2x 8-pin PCIe power connectors. Would I simply need to buy a 2x 8-pin PCIe power connector or is there anything else more subtle I'd need to consider?

Also, am I right in thinking these 8 pin connectors are sometimes referred to as 6+2 pin?

Many thanks.

There are only 6 pin or 8 pin connectors on GPUs.

The 6+2 plugs fit either the 6 pin or 8 pin.

Likely your psu has a spare cable, or the existing cable has a +2 not currently plugged in.

Make sure not to mix the 8 pin with ATX power as they are not compatible so likely to result in smoke.

Thanks, decto. I notice that there is a 2 pin connector dangling next to the 6 pin connector.

You shouldnt be able to do this in theory because they are a different shape.

This is 6+2 meaning you can use it as 6pin or 8 pin
