The +12V rails can deliver more amps than their specifications suggest before OCP shuts the E11-1000 down. Its minor rails also go quite high with load regulation and ripple suppression kept under control. Finally, the 5VSB rail has a rather conservative 4A limit.

Over-power protection's triggering point is set at a normal level, while OTP looks to be set low. With that said, this is a 40°C-rated PSU when it comes to continuous full-power delivery, rather than a 50°C one.
