According to slizone, they recommend a larger psu for dual 480's. I would go modular to help air movement within the case and I prefer Corsair. Slizone recommends a Corsair 950 watt and with you wanting to overclock, I would say go with the Corsair 1000 watt just to have wiggle room.

I haven't seen any hard numbers on OCed GTX480 SLI power consumption but you'd probably have to go up to a 1000w+ PSU in that case. My first choice would be the Enermax Revolution 85+ 1050 but you should check the EVGA forums to see if the compatibility problems with Classified MBs have been resolved.

2nd choice:
Antec Truepower Quattro 1200

other options:
Thermaltake Toughpower 1200 (overpriced)
InWin Commander 1200 (only 3 year warranty/additional $15 off with "SHOWERS15" coupon code)

Also good but may still be cutting it close depending on how far you OC the GPUs:
Corsair 950TX
Corsair 1000HX
OCZ Z-series Gold 1000
Thermaltake Toughpower 1000 (overpriced)
