Hello Everyone, I'm wondering if there is any way to measure the amount of power being used by the PCI rows on the LB. I' thinking of adding a GT 640 for an additional 65W. I know it isn't a powerful card, but it's a cheap way to get 10X the number of cuda cores I have now (GT 120 has 32 cuda cores). I don't need to power a display with it. I already have: Apple 5870 = 75W (6 pin) + 75W (6pin) + 38W (PCI) = 188W (AMD Spec) Apple GT 120 = 50W (PCI) = NVidia Spec The GT 640 would only use 65W from the PCI lane, so i'm good on paper. I'd just like to see what I'm actually using. thanks!!!
