Undervolting as mentioned above is a must.
280x's get near 300w in a hurry @ stock volts of 1.2v. The 7970 GHZ Ed @ 1.256v was a bonafied 300w card.
To accomplish putting 4 of those 280x's on that 1200w unit, you would most likely need to get volts down to 1.1 or under.

I don't know since I do not own them. My guess is probably 700+KHs a card undervolted if it is configured properly.
Hm, so what rate you think i will get with this setup each card undervolted? :S
Undervolted: yes. Otherwise you are pushing it.
I was just wondering will this power supply: http://www.corsair.com/power-supply-units/ax-series-power-supply-units/ax1200i-digital-atx-power-supply-1200-watt-80-plus-platinum-certified-fully-modular-psu.html
Be able to run 4 of these cards? : http://www.newegg.com/Product/Product.aspx?Item=N82E16814127759
