I'm trying to upgrade my ThinkCentre M81 (i5 2400) to a dedicated GPU. I purchased a 600w PSU and am trying to install a Radeon 480x. I am unable to post after installing this GPU, however, a Radeon 5770 I had lying around booted just fine. Is there a reason this GPU does not work? Has anyone had success installing a rather new GPU in this machine?
