Installing NVIDIA gtx 1080ti into a dell precision t3610

I am trying to upgrade my dell precision t3610 with an NVIDIA gtx 1080ti. I got a power supply of 685 watts from dell, but the problem is the proprietary power supply (it is a hot swap that feeds power to a little board which has two 8 pin female connectors and one 24 pin female connectors) doesn’t have enough connectors. NVIDIA gtx 1080ti needs one 8 pin connector and one 6 pin connector. The 24 pin connector and one 8 pin connectors are connected to the motherboard and the other 8 pin connector is free. I could connect this available 8 pin connector to the graphics card but I still have to connect the remaining 6 pin connector on the card. Do you know if there is any work around this ? I also bought a 650 W power supply from corsair but Dell makes it really hard to replace their proprietary power supply with something else.
 
Everything I found online is that the PSU is very proprietary and you cannot put a standard ATX PSU in this one. You could buy this instead though:

The there is the cable, you need the 6 pin. Unless there is a second slot for it or two 4pin Molex that can be converted to a 6 pin PCIe power cable (which I do not recommend) you wont be able to provide the power properly.

This is a workstation system and was made to run low to mid end workstation class GPUs that run 1 PCIe power cable. I can't really find anything online to add another PCIe power cable except there is a single 8 pin to dual 8pin but that's used to run two lower end Quadros.

XxDarkmario, thanks for your reply. I got the upgraded proprietary power supply from dell, which is 685 watts. So wattage should not be an issue. As per your concern about airflow, I could leave the computer case open on one side and blow a fan on it whenever I am doing my simulations that require GPU calculations, My usage will be running some simulations that require GPU for one - two hours straight at a time. I am not upgrading for gaming purposes.

Jimmysmitty, thanks for your reply. Yes I already got this power supply. My original power supply was 425 Watts. From what is shown in picture ( from the link you posted from ebay), the 24 pin connector and one 8 pin connector ( the one with white connectors ) go to motherboard which are connected through the 24 pin connector and the white connector of the circuit board shown in the picture. It is left with only one connector ( the black one that is shown in the figure of the link you posted). This connector can go to the 8 pin connector of the GPU but the 6 pin connector of the GPU is still left out.
