I have an old Dell T7400 with a Nvidia Quadro FX1700

Can I upgrade this graphics card to an ATI Radeon HD 5770 ?

Hi Demo,

Sorry for the delay in replying, I plugged in both 6 pin power supplies into the card and it worked straight off
It may be that the card is not getting enough power from the T7400. My card needs 150W which works fine, I note that you card needs 170W. Whilst the PSU has more than enough power I think the amount going to the graphics card is limited. May be wrong though .

Thanks Graham.

I managed to get to work. Found a spare molex cable running from the psu, bought a molex splitter and used the 8-pin adapter the card came with.
