Hello I have a Dell optiplex 9020, i7 4770, 600w evga with 24-8pin adapter. I am trying to install a referbished msi Rx 460 purchased from newegg. This model does not have secondary power input. I'm getting an code 43 message in device manager. I have resorted to fresh install of windows 10, tried again. Then ddu in safe mode. Gpuz shows the card as authentic. I have read a few posts indicating the mb and GPU do not play well together possibly due to low power to the pcie slot. Any advice would be helpful. At this point I'm looking to get a used lga 1150 mb to see if that is the problem.
 
I don't have an alternate system to test it right now there, but there are a few on Craigslist I'm looking at to swap the CPU and then sell the optiplex. Thanks for the info on the case.
 
Got an Asus h81m-a motherboard with 350w and plugged in the Rx 460 with a fresh windows. Gpuz and windows show the card and driver's loaded fine but there is still a code 43. I am starting to think the card was not referbished properly.
