I am still a Mac Pro newbie, although, I know a lot, I really don't know a lot. That being said, I have a few Qs.

I am using an old (as in, out of my no longer used PC) Sapphire radeon HD 7950 (2x6 pin) without a flash. I have ordered an Nvidia GT 120 so that I can use the boot screen. This setup will be until budget allows a GTX 980 or 970.

In my PCIe slots I have the 7950, and Plextor M6e 256 SSD.

After a bit of research, I am concerned about power draw when using this setup.

Any pointers or suggestions are appreciated.

Thanks, I did not want to draw too much power and fry the logic board. I never OC a GPU and only use for basic video editing with some 3d effects, so being able to have boot screen for switching drives is added bonus.

I will look into flashing the 7950 or having MVC do it (I ordered the GT 120 from him).
