Per the spec you have three volatages
4.5 Amps max (54 Watts) per logic board/power supply connection.
I personally don’t like pressing a sustained load more than 3 Amps per drop. I also like to disperse the load across different rail lines if the power supply offers it.

Hi Dan,
Thanks for your response. I’m trying to figure out where I can get power for this card. The specs say the theoretical maximum power consumption of the card is 40w/136.5 BTU. Would you recommend that I possibly try to find a secondary auxiliary source as opposed to trying to use the SATA connection?
First, Are you sure you have the needed drivers for it? Many of the newer cards won't work in this older Mac Pro. The spec sheet max power consumption is the worse case. Are you expecting to push the system to the wall? I hope not!
What are you planing on using your system for?
