Molex-to-pcie converter? Help on Setup Litecoin mining rig?

[AMAZONBTC]

So i was following this tutorial: http://www.coinminingrigs.com/how-to-build-a-6-gpu-mining-rig/#comment-14196
And when i was purchasing the stuff, i couldnt find TWO molex-to-pcie adapters (8-Pin(6+2) PCI Express 2.0 Conversion Cable) for the LEPA 1600 Watt Power Supply. I mean, i can find it on amazon.com but i am purchasing at www.amazon.co.uk! Can someone send me the link of a deal on amazon.co.uk? This cables confuses me alot and since i am a newbie im a bit lost!

Thanks
