• A900-PWR1200-A—Provides 975 W output power for system 12 V power with the A903-FAN module.
As most of the system configurations using A900-RSP3C-400-S RSP modules require power exceeding
550 W, we recommend using the A900-PWR1200-A power supply with A900-RSP3C-400-S RSP
modules. See the figure below.
