I have a Dell Optiplex 745 PC. This PC is a small sized case with a 280 watt psu. The current draw under load is around 90 watts.
The spec sheet for the PC is here (mine is the 'Desktop' version):
I have the riser option in the PC which means that it will accept a full-height PC-Expressx16 card but there is a drawback. The CPU heat-sink obstructs full length cards from being placed so I am looking for a full height card that is a maximum of 16cm (6.3 inches) long.
I want the highest performance card within the dimension and watt limits but I can't seem to find a single source of information to do with the physical dimensions of graphics cards and their power requirements.
If you would be so kind, perhaps someone could make a suggestion.
