OR
an EVGA PowerLink along with 2 x SATA power to 6pin + 1 x SATA power to 6pin then combining the 2 x 6pin to 8pin, then combining the stock 2 x mini 6pin to 8pin
OR
Use a 2nd external PSU for the 2 x 8pins. Power on the PSU before turning on the Mac Pro, and reverse order shut down the Mac Pro and then turn off the PSU. So external PSU is always 1st and Last.
OR
Use an eGPU box with its own ample power supply
Will run fine in Vega 56 mode without any power modifications
This video card is Plug ’n Play (gpu power cables mandatory)
