So I just ordered one, and I'm curious about something before I go out and drop some money on a new PSU. Currently I have a multi-rail PSU with two 25a rails.
Am I correct in assuming that the card will pull 75w~ from the PCI lane (pulling off the CPU/mobo rail)? I have no idea if modern boards still provide some of the required power to the GPU, google wasn't much help.
If so, my 25a GPU rail (300w) should be plenty for this card, yes? Considering the highest power draw ratings that I can in reviews are around 270w (not total system draw). AMD is also no help with their advertised TDP ratings, seems as though every reputable reviewer has proven the cards easily raise above it.
