That really depends on the type of 280x. In my experience Sapphire Toxic needs more power than the rest. If it's not a Toxic you should count 230-270W per card (undervolted between 1080mV - 1150mV). For Toxic 300W to be sure. I'd go for 3x 500W (650W) PSU (should be able to get gold cert. for $100 each). If you dont have mobo with molex, you should get some powered risers to reduce the risk of burning your mobo.

I have a 760 Platinum and a 1000 Gold, Both Corsair.
Would you go 3x 280x at the 760W and 3x 280x + system on 1000W?

I will only run one miner with 6 GPUs on the same motherboard, so the Wattage from Mobo is just counted once
That might work. Which mobo is that?

I run 4x 280x on a 1050W Cougar PSU. It consumes 1150W when everything is up, so a 1500W PSU should do it with 6 cards.
I run 4 miners with 3 280x each, with 850w PSU each. so I guess 1600W al least.

Hi, I will be running 6x 280x Graphicscards with one mobo, CPU, ram etc.

What would you say I need in terms of power?

1000W + 760W Platinum? To less?
