So I want to build a 6 gpu rig but this PSU

Thermaltake TPG-1200F Toughpower Grand 1200W
http://www.thermaltake.com/products-model.aspx?id=C_00002400

The thing is is that it only have 4 pci-e connectors. Is there a way around to connect my 6 cards?
I don't know if this is what this cpu to pci-e converter tries to achieve no?
http://www.thermaltake.com/Power_Supply/Accessories_/PSU_Cable/C_00002413/CPU_8Pin_to_Dual_PCI_E_6_2Pin_Splitter_Cable/design.htm

If there's no way to work this out I know there's only two options:
Buy another psu like a 500 watts one and use both, connect 4 to the 1200 watts and 2 in the 500.
Or
buy a 1200 watts psu that has 6 or more pci-e connectors

I wanna know what can I do with the one I have already, any help appreciated guys.

Look what connectors you have on your cards 6pin-125W 8pin-150W then it will be easy to understand, as you did not specify what models you have. I would assume this PSU has at least 16AWG wires and uses all 8Pins/wires...

Hmm I understand ohhh. So I have 4 580 and 2 570.

so if the 580's have 8 pins  and the 570's have six pins

it could be hard.

if they all are six pins  you should be able to do 5 for sure and 6 maybe  depends on how you clock

The cards, all use 1 8-pin connector, and I have two nitro+ rx570 that uses also an extra 6-pin but it says on the website its optional.

Well, all use 1 8-pin connector, and I have two rx570 that can optionally use a 6-pin also. all of them can be powered with 8-pin connectors. But How am I gonna do it if I only have 4 pci-e ports with double 8-pin cables? do I use like 1pci-e to 2 pci-e adapter in 2 or something?
