Re: [Avid-L2] Where is my dream GPU???

I googled around and power spec for the card says 500 watts.  I read conflicting specs on what the Mac Pro has power wise.  I read 75 watts through the PCIe bus and 150 watts each through the 6pin mini connectors on the mother board for a total of 375 watts, but someone said they though it was on 75 watts for each of the mother board 6 pin mini connectors.  Did you have any power issues or did you have to do a pixas mod?  I would think even 375 watts would be a bit limiting to a GPU that wants 500 watts

That’s the identical card I had.  It worked very well and I never missed the boot screen.

So I found one on Amazon that I'm going to try.  I've been told it's good bye boot screen but this is my last ditch to keep this Mac Pro alive for front line edit use.
