Two 6-pin connectors

[Conleak]

Okay, so, I bought a new power supply (http://www.maplin.co.uk/p/g7-780w-atx-pc-power-supply-n...) and it has 2 6-pin PCIE connectors. My graphics card has an 8 (6x2) and a 6 pin connector. This power supply has no adapter slots, slightly strange, so, I was wondering if I could connect the 2 6-pin connectors to the gpu and it would work? I have not been able to test this and the power supply is boxed up, if there is no solution, I can return it.

My Graphics Card: Geforce GTX 770 2GB

No, your GPU needs an 8-pin connector and a 6 pin connector.
They do sell adapter cables for that though: http://www.amazon.co.uk/s/ref=nb_sb_ss_c_4_5?url=search-alias%3Dcomputers&field-keywords=8+pin+adapter&sprefix=8+pin%2Cnull%2C282

It wouldn't

You could use a adapter like this one (haven't try it yet and its possible that the power supply will not deliver enough power to the gpu)

or you could try to return/sell the psu and buy a new

I have an adapter like that, should I try it?

I doubt that you will cause any damage, but I am afraid that this high end gpu will not be "fed" well enough. I am not 100% sure about that, so you could wait about the opinion of other members...

The adapter was included with the graphics card, so it should be fine?

Its exists mainly as a temporary solution rather a permanent one...

I would be very wary of that psu. Any 780w unit that comes with only 2 6pin pegs is absolutely a disaster waiting to happen. A well made psu of that capacity should have at least 2 6pin and 2 6+2pin connectors. I would suspect that the actual output of that supply is more along the lines of 400-450w. If you can still do so, return that psu and purchase a well made unit from XFX, Seasonic, Corsair (TX series), etc. If you are on a budget, let us know and we can make specific recommendations.

A psu is the LAST thing to compromise on - if it goes, especially a "bargain" psu, it may also take your m/b, cpu and gpu along for the ride.

Okay, yeah, I mean, the reason I got this PSU was because I wanted to be on the safe side and make sure my gpu was getting enough power. I tried to get the Corsair 750M but it was sold out and I was kind of in a hurry, I should be able to return it.

Check the specs on the side of that psu. If it is multi-rail, make sure you have at least 20a on each rail. You should be ok to run it with one of the 6 pins and using the adapter off a molex as they are typically on separate rails on that type of psu. If you can wait - do so and get a "name" psu. Amazon UK has THIS EVGA which is a solid unit.

What about this one? http://www.scan.co.uk/products/750w-corsair-builder-series-cx-85-eff-80-plus-bronze-sli-crossfire-eps-12v-quiet-fan-atx-v231-psu

That will work fine.
