Installing two PSUs in one cabinet may require a higher fuse. It
all depends on what you're powering. The second unit itself will
draw minimal current with no load on it. If nothing else make
sure you don't use a fast slow fuse, the increased power-on
serge from the two may take it out and that has nothing to do
with the load - it's just the jolt of the initial electrical serge into the
system.

Question is...why do you need to add a second supply The new
one is over an amp, yes ...plenty powerful for any combination
you can fit into a single cabinet. Hell, I beat you you could power
two cabinets with one of those guys. Possibly you're
constructing a cabinet without a supply in it and housing it's PSU
this other box

If it is going into a the same cab, one thing you don't want to do
however is mix the outputs of the two supplies on the power rail.
This would very bad! If you stick two PSUs in one rack, get a
second power busboard.
