According to HWiNFO my GTX 970 is pulling a maximum of 193 W while gaming. Nvidia specs state a max of 145W. Can they pull more if they need to?
Well, if they couldn't, you couldn't overclock them very well, could you?

Plus, if youa re talking about Furmark, that may exceed the specs even on stock as it is absolutely gruellign for th GPU.
