The way some GPUs power requirements are quoted vary greatly. Some will say 650 watts which means the value is what is estimated with the GPU and Motherboard and all others in a PC would require.
What I usually do go the Manufactures website and see if they quote the real TDP (total max power at full normal load) for a GPU. By Manufacture [MFG] I mean compare GPU Chip MFG and card MFG and see if they make sense. Hope this helps.
