You'll need the extra circuit. 3 480s consume as much as 937w according to Hardware.info

937w / 3 = ~312w per card. Add another 312w for the 4th 480 and it gives you 1249 watts giving you only 191w left for your CPU (I assume you're running a quad core), motherboard and your drives. Good luck. I guess if there's a blackout that hits your surrounding area then we'll know where it came from.
