Where do I find molex connectors in my PC

[A FAT DONKEY 55]

I have a Dell XPS 8700 with a 460 watt PSU and here are the rest of the specs:
Intel core i7 4770k 8mb cache up to 3.9ghz
12gb 1600mhz dual channel ddr3 ram
NVIDIA Geforce GTX 645
1TB 7200rpm SATA Hard Drive
I want to upgrade my graphics card to a EVGA geforce GTX 750 TI SC or FTW edition, in the case of the FTW Edition I need a 6 pin PCIE power connector I looked in my system and saw I didnt have one, but the graphics card has a molex to 6 pin adapter but I dont know where to find molex connectors in my system, could someone please tell me where I can find molex connectors in my system.

The molex connectors come out of the psu.

they come out of the PSU. The single row rectangular heads with 4 holes running horizontal.

This is what 4-pin Molex connectors look like. Both white and black are common.

Some of the cables coming from your power supply are Molex cables. I've never heard of a system that didn't have several of them, they're one of the most basic and ancient connectors around. They're mostly just used for case fans since the standardization of SATA drives. I can't imagine what would be in your system using them all up.

Can you take off the panel on the other side of your case? Perhaps they're tucked behind the motherboard tray.

There are usually a couple of spare power cables coming from the PSU, with molex connectors on the end of them. If your PSU has any spare ones, they will be secured to the wiring harness with zip-ties to keep them out of the way of any fans.

If there are no such spare cables you can buy a molex "Y-splitter" cable" which converts a single molex plug in to two molex plugs: http://www.ebay.co.uk/itm/like/180336528667?limghlpsr=true&hlpv=2&ops=true&viphx=1&hlpht=true&lpid=108&device=c&adtype=pla&crdt=0&ff3=1&ff11=ICEP3.0.0&ff12=67&ff13=80&ff14=108

To use the Y-splitter you unplug a molex power cable from an IDE drive, plug the splitter in to the that molex, then plug one of the two molex tails into the drive. That leaves you with a spare molex-terminated power cable.
