Where to use this cable:
It is used to replace your broken,damaged,cracked,unusable power cable.
Requires two free 6-pin standard PCI-e power output sockets on your Mac Pro mainboard.
the 6 pin power connectors supply 75W on each port, plus you get another 75W from the PCI-E lane where the GPU card is installed. Therefore so long as the maximum power draw on your GPU does not exceed 225W, this cable should suit your situation.
