What you read is nonsense, a 750 Watt PSU is fine to run 2 280X. they use little more power than the GTX 770, its marginal.
If you read all the reviews they say a min 1000 watts is needs to run the 280x toxic x-fire

Which reviews? none of the ones i read say that. some bedroom PEBAK kid?
They are BIOS locked to 225w, they will not pull more than 225w each at stock, you can increase that by increasing the board power line by 20%, that takes them to a maximum of 270w each, thats a maximum of 520w combined.
I'm on my phone right now.I'll show you when on desktop When on full load It draws 460 something watts on 1 card. I think u need to read again.
The PCB wouldn't survive that, they have limits to how much power you can pull through them, which is why they are designed to throttle once they reach a set TDP limit.
I'll show you the review. I thought it was wrong too, but read the power draw twice and it does say in 3 reviews you'll need a 1000 watts min in x-fire
I have that exact same thing if i under-volt to much, turn the GPU core volts up a tad and it will go away.
are you overclocked?
