However they can place a disclaimer that you need a compliant PSU/motherboard that can handle the massive 5watt over spec
its spiking to 85W on pcie.
Max standard for 12V is ~66W.
They are going over the spec by 20W already. If you run crossfire or OC then its much more..
consistend power draw and spiking are two different things. You can't take OC into account as thats completely on the user. ( plus every oc'd card pulls way beyond spec as well ) only stock crossfire scenario should be taken into consideration.
1) the 480 doen't generate nearly as bad of power spikes like the asus 960 strix (220 watt spikes consistently) which hasn't received any complaints. so just ignore power spikes for now.
2) consistend, or average, watt trough pcie. people have been running heavely OC'd crossfire/sli setups for years without motherboards blowing out. Even lower quality mobo's should be fine.
3) if the max standard is 66watf then the 960 mentioned has also failed specs. also, specs isn't everything, motherboards can set higher limits trough software/hardware if needed.
Despite all this, MAYBE dual 480's on a cheap mobo will cause your computer to shut off, in that case, no harm is done.
