Well this is frustrating and after 4+ hours including 2 with Dell support, my T620 is being returned to Dell. The answer is; yes, you can install a third party video card into a Dell T620 but that video can ONLY be used as a secondary processor… it will NOT be capable of producing video output. This explains why add-on video cards show up in Device Manager and install in Windows but do not produce video output when you connect a monitor to them. For more details click HERE and note the SECOND post down from DELL-CHRIS.
While I am here, I might explain that currently only two NVidia cards (including the C2075) and ATI AMD FirePro V7800 are “supported” by Dell. Each of these cards REQUIRES external power. The power distribution board is UNDER the main server board (I THINK you can get to it by taking off the outside panel, but I have not tested this).
In my case I was trying an old Radeon card and a FirePro V4900, neither of which should require power. However I thought it was worth verifying so I did. Below are the power ratings for each slot in a Dell PowerEdge T620 and you will note that the full slots (x16) provide up to 75 watts of power and the FirePro V4900 has a peak of “Less Than 75 Watts” so power should not be a problem. As described above the power was not my problem, it was the intentional design.
