DSI510 LED lights going off after attempted GPU upgrade. Help!
I tried to put a AMD Radeon RX 5700 in my 2009 (flashed to 5,1) Mac Pro. I saw online that you can use one of the SATA ports for additional power for the GPU. My mac pro now wont power on. When I power on the Mac Pro, the DSI510 LED lights on the CPU tray, next to both CPU’s light up RED and it wont boot at all. Did I just blow my CPUs? Will buying new ones fix the issue? Help!
