I'm not sure on the specs, but if the card requires 22 amps then 18 wont cut it. It will cause a power sag (not getting enough power) which will cause it to become damaged. Same goes for if it requires 18 amps but your overfeeding it (power spike) and that willl also cause it to become damaged.
im not sure on that exact model card but usually thats the way it is with anything receiving power.
hopefully i was some sort of help.
