Emacs H1U-6250P 250W 1U Server Power Supply — RoHS Compliant Single PSU

A slim, reliable 250W supply for 1U rackmount servers and appliances.

The Emacs H1U-6250P is a 250W single power supply in a 1U form factor for rackmount servers, network appliances and industrial computers. It accepts 100–240V AC input, includes built-in fan cooling and is RoHS compliant. It suits IT teams and integrators replacing the original unit in 1U systems.

Fitting Power Into a 1U Chassis

A 1U server is only 1.75 inches tall, so its power supply must be just as slim. Standard ATX or PS/2 supplies cannot fit, and many 1U chassis require a specific connector layout.

The H1U-6250P is the Emacs 1U unit designed for this space. It mounts in the original location and connects to the existing cables, restoring power to firewalls, appliances and small servers without chassis changes.

Stable Power for 1U Appliances

A 250W rating supports single-processor servers, firewalls, network appliances and industrial PCs. The built-in fan moves air through the slim housing to maintain safe temperatures in dense racks.

Compliance and Reliability

RoHS compliance and Emacs’ industrial heritage make the H1U-6250P a dependable choice for continuously running rackmount equipment.

Setup Instructions

How to Replace the Emacs H1U-6250P

1. Shut down the 1U server, unplug the AC cord and press the power button for a few seconds to drain residual power.
2. Open the side panel, photograph the cable routing, then disconnect the power cables from the motherboard, drives and any graphics card.
3. Remove the mounting screws or release latch, take out the old unit and install the replacement in the same position.
4. Reconnect every cable, close the case, plug in the AC cord and power on to confirm the system boots and the fan spins.
