Hello,
After doing some research I have come to conclusion that there is an additional power supply supported for this unit. If you take a look at the Quick Specs for the Elite 8300, you can see what graphics cards are supported (found on page seven and eight) as well as the power supply information (found on page 12):

With that being said, you may also be able to run a molex to a six pin connector. I do not know exactly which one you will need since I don’t know the model of your current graphics card or Elite 8300.
Hope this helps a bit, thanks!
