Don't know how to connect GTX 780 to power supply

Really disappointed.

I am a n00b but I would have hoped there was at least some help on how to plug this into the PSU.

I have a Corsair AX760i and the EVGA super clocked GTX780

Can somebody please help me understand what needs to be plugged in where

Many thanks,
Andy

Plug the PCIe power cord from the PSU into the card, really simple. Looks like you have a modular PSU, so just dig around the cables until you find the ones you need, you can look at the card and count how many pins there are and put two and two together.

Please don't say it's simple, I clearly don't think it is and you know what you are doing.

Does it need two six pin connectors or just the one 8 pin connector coming from the graphics card?

The EVGA GTX 780 Superclocked w/ ACX Cooler requires one 6-pin and one 8-pin PCI-Express power cable.

Since the Corsair AX760i's modular PCI-E cables only have (6+2)-pin PCI-E connectors on them there will be no problem.

You can use two separate cables each with a single (6+2)-pin PCI-E connector on them or you can use a single cable that has two (6+2)-pin PCI-E connectors on them.

The graphics card requires an 8 pin PCIe power connector and a 6 pin PCIe power connector, plug those cables into the PSU and then into the GPU.

The card came with an 8-pin connector that splits off into two 6 pin connectors

It also came with a 6pin connector that splits off into two flat shaped four pin connectors

Do i even need these?

Do not use any of those adapter cables that came with the graphics card.

Fantastic. That's a good start, I think they were making this more confusing because I thought I needed them...

We'll do this through the process of elimination if thats ok? Do I need any of the flat shaped four pin connectors?

I really appreciate this help by the way. A lot.

No. You do not need to use any 4-pin Molex peripheral connectors on any power cables that lead to the graphics card.

Ok then that leaves two cables that are the same.

They are 8 pin connectors that go to a six pin connector with two hanging separately.

My guess at this point is to plug both the 8 pin ends into the PSU and then put one 6 pin in the six pin gap with two hanging free and the other 6 pin into the 8 pin gap along with the two other pins.

So (from PSU to card) that would be an 8 pin to a six and an 8 pin to a 6+2 pin?

Yes. That was one of the methods I mentioned earlier.

The other method was to use a single cable that has an 8-pin on the PSU side and with two (6+2)-pin PCI-E connectors on the other end.

Absolute legend. You have made a very depressed gamer happy again. I really appreciate the help. It was painful how much it needed to be broken down to me but we got there. Massive, massive thanks.
