Dell T7500 running two GTX-680's

Hello all and welcome to my first post.

I am trying to get two nVidia GTX-680's to run in a Dell T7500 tower. The problem is a STUNNING LACK of 6-pin PCIe power cables (there are only 2?! Really? Only 2?). From what I understand both of the cards require both of the supplemental power ports to be charged by the PSU and that means I need four 6-pin PCIe power cables and as I have said there are only two.

The question becomes: Can I use two (2) StarTech Model SATPCIEXADAP 6" 6in SATA Power to 6 Pin PCI Express Video Card Power Cable Adapters to get the power I need? Is this safe? If this is not the way to go is there another work around?

I just can't understand why an 1.1 Kw PSU has only 2 available 6-pin plugs.

Any advice would be very helpful. Thank you all so much.

David

EDIT: I forgot to add that I wish to run these cards in SLI (if that matters to the power thing that is)

you can use two molex to one pcie adaptors x2 for the second card but no its not safe..the safest way is to upgrade the power supply to 650-750watts that will have all the pcie power cabled included

and thats weird that your 1100w psu has two pcie connects..maybe its old so yea i would still recommend upgrading to a gold efficiency rating power supply with 4 pcie 6+2 pins meaning it will have four 6 pin power connectors with optional two extra pins as some cards take 6 pin and a 8 pin
