Guest Mariner19 Posted December 12, 2021 Posted December 12, 2021 Mac Pro 5,1 2010 model assembled 04/2012. Would like to install a Sapphire Nitro+ Radeon RX570 GPU. Total power draw per factory specs is 195w. I noticed that that the GPU has a 8pin and a 6 pin power port. Now I realize the x2 mini 6 pin connectors on the logic board provides 75w each and the GPU slot provides an additional 75w for a total of 225w. Am I going to be running into problems using a mini 6 pin to 8 pin PCIE cable and a mini 6 pin to 6 pin PCIE cable? Thank you Source: MacRumors
