I have a Mac Pro5,1 that currently has 1) GTX 780 running off Mac internal PSU; 2) GTX 780ti running off external PSU.  I want to replace the 780 with a 1080ti, resulting in a 780ti _ 1080ti.  The question is, can I run the 780ti off the Mac internal power safely?  The 1080ti of course would run off the external PSU.

Try it and let us know.

Before asking a question, check your "Personal Settings" and be sure that you have "Brain Services" set to "On".
