1.85A is pushing it a little. It would be better if you can get that load figure lower, say down around 1.6A. This is easier on the "on the panel" supplies. But if we're talking some sort of heftier internal supply (like the Pitt ones, Doepfer PSU3, etc), this should be OK as those manufacturers tend to build some headroom into their P/Ss. If so, then just take some care to distribute the +12V rails' current load across the distro boards so that one of them isn't bearing the brunt of the current load while the other loafs along.
