Which cable do I need to connect a Rosewill Capstone 550M to a GTX650Ti?

Bought parts to build a computer. The RC550M is modular and has 4x8-pin rails.
I have a 6-pin PCI-e to 2x4-pin LP4's. Connecting a single LP4 from the PSU causes infrequent shorts in the GPU, and connecting two LP4's from the dedicated power cables of the PSU also gives shorts; I assume this means I need two 8-pin to LP4's to go from PSU to GPU, each on a different rail.

What cables do I need?

Notes:
The PSU was second-hand and did not have any cables aside from the dedicated cables.
By dedicated cables, I mean the braided power cables coming from inside the PSU which cannot be removed without opening the PSU.
The GPU only came with the 6-pin PCI-e to 2x LP4's.

Is this your Rosewill 550W PSU? http://www.newegg.com/Product/Product.aspx?Item=N82E16817182262
If so, and you didn't get the modular cables, you can't connect it to the PC. The missing modular cables are:
2x 6+2-Pin PCI-E Connector (you need one of these for the gfx card)
5x 4-Pin Peripheral Connector (these are for the drives that use Molex connectors)
6x 5-Pin SATA Connector (These are for drives that use SATA power connectors)
1x 4-Pin Floppy Connector (seldom used cable for old floppy disks)

The fixed cables should be:
1x 20+4-Pin Main Connector (for the MB 24 pin header)
1x 4+4-Pin ATX12V/EPS12V Connector (for the 4 or 8 pin MB CPU power header)
