Electrical power for the FBW computers is a minor problem: the big problem is hydraulic power, and that's the primary role of the RAT device: to provide hydraulic pressure. The computers can be driven by batteries if necessary, as are the radios, etc. Look at the situation when BA's G-BDXH lost all four engines in Indonesia: even without engine power, the crew were able to communicate with ATC (actually, with a relay aircraft that could receive the dust-attenuated radio signal).
