Well, a 12008 with a few (engine0 and 1) LCs in it actually draws like
600W which is fairly close to 13A, so personally I wouldn't be too
uncomfortable with 10A per powersupply for a router like the 3845, I'd be
surprised if it ever used more than 200-300W over time (even though I have
never actually tested it), ymmv.
