Replacement 400 W ATX Power Supply

This Replace Power unit is a standard ATX power supply rated at 400 W, intended for desktop systems that require a direct replacement for an original equipment unit. It delivers power through a single +12 V rail rated at 16 A alongside +3.3 V and +5 V rails each rated at 13 A. The grey enclosure houses a single cooling fan.

Fits standard ATX cases

Installation requires an ATX form-factor chassis and a motherboard compatible with the 20+4 pin main power connector. The supply accepts 115 V or 230 V input at 50 Hz or 60 Hz without manual switching. Its 17 ms hold-up time and sub-70 ms rise time support stable power delivery during brief mains interruptions.

Over-voltage protection guards connected components

The built-in over-voltage protection helps shield the motherboard, drives and expansion cards from damaging voltage spikes. A mean time between failures figure of 100000 hours indicates the design target for continuous operation. No modular cables or software utilities are included with this unit.
