160 W for the mentioned PowerColor Radeon RX 6600 XT Fighter.What is the TDP of this card? I am leaning towards buying a RX6x00 (granted, mostly for Windows use in games), but what I have available is an EVGA Powerlink.
As it has only one single 8-pin PCIe connector, it can‘t draw more than 150 W from the Mac Pros motherboard Dual-6 pin power connectors. So a Pixlas mod shouldn‘t be necessary.
