Precision T5500 Power Adapter Query

I have a question about the types of power adapters on the DELL Precision T5500 for use on EVGA graphics type cards. Hope some-one could please answer my queries.

So I have this T5500 with its stock standard 875W Power Supply Unit with two 6-pin power connectors.  The whole system originally came with an NVIDA Quadro FX 5800 graphics card and it was using a dual 6-pin to 8-pin adapter to power that card.  That card typically ran very hot so I swapped it out with a DELL NVIDA Quadro 2000 some time ago.

I’m currently researching an upgrade path and want to move from the current Windows 7 Ultimate to Windows 10 Pro and introduce a better GPU.  I have my eye on the EVGA GeForce GTX 1070 SC2 (P/N: 08G-P4-6573-KR).  Green PC Gamers site references a YouTube video showing fitting instructions to power an EVGA Geforce GTX 1080 GTX.  It looks like I can still use that same dual 6-pin to 8-pin adapter to power up the EVGA GTX 1070 SC2 graphics card.  I believe it should work without issue.

However, as an alternative, I also have my eye on another EVGA card. The EVGA FTW2 GTX 1070 Ti (08G-P4-6676-KR) but it looks like this card requires a "two" 8-pin connector input feed.  Is it possible to use this card on the T5500 PSU with some type of adapter that could be purchased?  To me, it doesn’t look like to be possible so checking here as well.

On the next level up is the EVGA GeForce GTX 1080 Ti SC2 Gaming 11GB (11G-P4-6593-KR) and on this card is a 6 pin and 8 pin power connector, side by side.  This is one of the recommended EVGA cards on the Green PC Gamers web site for the T5500.  So being a recommended model, what type of power adapter is needed?  I’m assuming you would need to use something like a single molex to 6-pin adapter and the dual 6-pin-to-8-pin adapter at the same time to power the card.

Any advice and guidance would be much appreciated?

Regards,
Tony G

    We've had great success using 1 x 6 Pin Male (standard on Harness) and 1 x 6 Pin Female to 8Pin Male Adapter when using cards that require 1 x 6Pin and 1 x 8Pin Power.

    You'll want to stay away from the FTW cards.  They will not fit inside the T5500 chassis unless you modify the PCI Bracket and Side Panel.  The cards recommended on our T5500 blog page have been verified to fit.

    These cards seem to be the best value w/minimal bottle-necking when it comes to the T5500 Workstation:

     

    EVGA NVIDIA GTX1660 Ti 6GB Graphics Card

    EVGA NVIDIA GTX1070 8GB SC Graphics Card

    EVGA NVIDIA GTX1070TI 8GB Graphics Card

    EVGA NVIDIA RTX 2060 6GB Graphics Card

    EVGA NVIDIA RTX 2070 8GB Graphics Card

     

    Let me know if you have any other questions.
