Enhance Technology ENP-7025B 250W 1U Power Supply

SKU CH-MB2H-0XY69

A 250 W 1U proprietary power supply with active PFC, 80 Plus efficiency, full-range input, 12 V and 5 V standby rails, remote on/off control, thermal fan management, and over-voltage, over-power.

  • TypeProprietary Power Supply
  • Efficient 80Plus certification saves energy
  • 250W output powers 1U servers reliably
  • Active PFC corrects power factor automatically
  • Full-range input handles 12V and 5V standby globally
  • Thermal fan control keeps acoustic noise low

Enhance ENP-7025B 250W 1U power supply

This proprietary 250W unit fits 1U rackmount and Flex ATX chassis where standard ATX units cannot be installed. It targets system integrators and IT professionals maintaining compact servers, thin clients or embedded appliances that require a direct replacement module.

250W capacity with active PFC and 80Plus efficiency

The supply delivers 12V and 5V standby rails with active power factor correction rated at 80Plus efficiency, reducing heat and input current draw in dense racks. Over-voltage, over-power, overload, under-voltage and short-circuit protections guard connected hardware. Headroom suits typical low-power CPUs and minimal drive counts; configurations with discrete GPUs or large drive arrays will exceed the rated output.

Replaces failed or noisy proprietary units

It serves as a drop-in swap for OEM power modules that share the same proprietary pin-out and mechanical envelope, restoring reliability without chassis modification. The upgrade is worthwhile when the original unit lacks active PFC, exhibits fan noise under thermal control or has lost regulation on the 12V rail. Builders needing standard ATX connectors, higher wattage or modular cabling cannot use this model.

Questions about this item

Will the 12 V rail on this 250 W unit handle the drives I am keeping from my old server?

The supply delivers a 12 V output rated for the full 250 W capacity, so existing drives that draw within that limit will run normally.

How can I confirm the 80 Plus efficiency is active after installation?

Measure input and output power under load; the unit meets 80 Plus levels when output is at least 80 % of input at typical loads.

Does the box include the proprietary mounting brackets and cables, or must I source them separately?

The power supply ships as the unit only; proprietary brackets and cables for your chassis are not included and must be obtained separately.
