The Z440 officially supports up to an NVIDIA Quadro K6000 12GB, which draws 234 watts, so it ought to be able to handle my Red Devil RX-570. The Red Devil specifies a minimum system power of 450 watts, and my Z440's PSU is 700 watts:
More detailed info: https://www.techpowerup.com/gpu-specs/powercolor-red-devil-rx-570-oc.b4455 Your GPU max TDP is 150W, meaning it will draw 75W from PCI-E slot and 75W from 8-pin cable. Your 8-pin adapter must have been very poor quality. I don't know what kind of adapter it was, but adapters which make 8-pin from 6-pin, are dangerous. Better to use 2x 6-pin -> 1x 8-pin adapter to correctly assign wires to each corresponding pin. -- With kindest regards, Piotr. ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Debian - The universal operating system ⢿⡄⠘⠷⠚⠋⠀ https://www.debian.org/ ⠈⠳⣄⠀⠀⠀⠀
