Seems the bundled cooler master psu only has 1 1x8 connector and my card requires 2 x 8 pin.

I have 3 molex connectors can i use these with an adaptor as well as my 1x8 to power my MSI GTX 770? or can you use a 1x6 pin to 2x8 adaptor?

Gutted really as the cooler master website has a picture which states 2 x 8 pin PCie


Il be upgrading psu when i over clock but need something to get by with now :)

You only have 396W available on the 12V rail. The stock GTX 770 requires around 190W (16A) max on the 12V rail. The PSU has 2 12V rails with 19.5A available on each and 1 with 19A (but watch the wattage max!).

Theoretically, you can run the 770 on just about any system with an available 396W and that much amperage on the 12V rail. Will a 770 work with this power supply, yes. Would I personally plug a GTX 770 into that power supply? No. It was designed for systems built around 10 years ago. This is evidenced by the available wattage on the 3.3V and 5V rails...
