“The EVGA GeForce GTX 950 is now available in special low power models, but still retains all the performance intact. In fact, several of these models do not even have a 6-Pin power connector!”
EVGA didn’t skipped any features to run the card without power, all of these cards are full-on GTX 950’s, with 768 CUDA cores and 2GB of GDDR5 memory.
