Asus Dual OC RX480 power supply cabling query

[Joff-turbo-nova]

Hi all

Its been a good few years since I did a PC build from scratch and I'm a bit unfamiliar with some of the newer tech that's available now.

My son sorted out the build list which included 16GB ram, i7 6700 processor and a Asus Dual OC RX480 GPU .

We are using a Corsair CMPSU-650HX PSU however I can't seem to find the right cable to power up the graphics card.

The PSU has power outputs that look like this (6 pin and 5 pin options)....

The RX480 has an 8 pin power input port like this...

What cable do I need to link the two together - do I need a 8 pin cable to 2 x 6 pin or will something else work - links to the right item would be great !!

Sorry to ask a bit of a noob question but I would rather ask than make things fizzle !

Cheers

Joff

IS THIS YOURS? Linus shows the connections.

If you look through the cables that came with your power supply, you should find some marked as "PCI-E". These will most likely be a 6+2 design (I'll add a picture underneath of the plugs) As you need an 8 pin, you plug both the 6 and the 2 pin connector into the card. The other end of the cable will have a connector that will plug into your PSU, simply plug it in where it fits, you can't go wrong.

Thanks for the reply, the main PCI-E cable from the Corsair PSU I have plugged into motherboard (an ASUS Z170-K) in the ATX port - I take it from your comments that this is not needed on the motherboard and to unplug this from the Z170 and plug it into the RX480?

It's currently plugged into the "ATX" plug in the top left corner as seen in this pic , near where it says EPU...

Ok, this is important. Do NOT plug the PCI-E into your motherboard. I know the plugs are similar and it's sometimes possible to make it fit (the corners on the plug should be different to prevent this from happening).

The plug you want to use on your motherboard should be marked "CPU power" and will either be an 8 pin plug or 4+4 and you use both. The reason you need to use the correct plug is because the wire layout is different, and plugging the PCI-E into your motherboard will short out your PSU.
