Silver metal 1U ATX power supply unit with rear fan grille and cable bundle

Mean Well

Mean Well IPC-250 12V 15A 250W Industrial 1U ATX power supply

SKU CH-27J8-6GEXN

A 250 W ATX power supply with a 12 V 15 A output, built-in active PFC and forced-air cooling for 1U rack systems

  • TypeAT
  • Universal AC input works worldwide without manual switching
  • Active PFC improves power efficiency and reduces harmonic distortion
  • Low-profile 1U design fits compact rack-mount chassis
  • circuit overload and over-voltage protections safeguard connected hardware
  • Built-in DC fan delivers forced-air cooling for stable operation

Industrial 1U ATX power supply

The Mean Well IPC-250 is a 250 W AT form-factor unit designed for 1U and 2U rackmount chassis. Its universal AC input accepts full-range mains voltage without manual switching. Active power-factor correction and built-in short-circuit, overload and over-voltage protections suit industrial and server deployments where uptime matters.

Sustained-load behaviour

Forced air cooling from the integrated DC fan maintains thermal stability during continuous operation in confined rack spaces. The PS-ON signal input allows remote power sequencing, while power-good and fail-signal outputs give monitoring systems real-time status feedback. Protections engage cleanly without latch-up, keeping connected loads safe under prolonged demand.

Upgrade context

This unit replaces older fixed-voltage AT supplies that lack active PFC or remote-control signals. The jump is worthwhile when a rack build needs full-range input, standardized fault reporting and a low-profile footprint. It does not address builds requiring higher wattage, modular cabling or newer ATX12V connector layouts.

Questions about this item

How much heat and noise does the built-in DC fan produce when the IPC-250 runs continuously at 250 W?

The unit uses forced air cooling from a built-in DC fan; Mean Well does not publish acoustic or thermal figures for continuous full-load operation.

Which cables or connectors must my system already provide for the IPC-250 to power on?

The supply requires a standard ATX motherboard connector and a PS-ON signal from the board; no proprietary cables are included.

Will the IPC-250 work with an older AT-style motherboard that lacks the PS-ON pin?

The unit expects a PS-ON signal to start, so an AT board without that control line will not turn the supply on.
