KHACHIMO 1U 250W ATX Power Supply

The KHACHIMO EFAP-S250 and EFAP-M251 are 1U form-factor ATX power supplies rated at 250 W. They carry 80PLUS Bronze certification for improved energy efficiency. These units suit compact servers, embedded appliances or thin workstations that require a standard ATX pin-out in a slim chassis.

250 W capacity and headroom

The 250 W output handles low-power CPUs, integrated graphics and a modest complement of drives or add-in cards. Systems with discrete graphics cards, multiple storage arrays or high-core-count processors will exceed the available headroom. Builders needing higher continuous power or additional PCIe connectors should select a higher-wattage model.

Questions about this item

Will this 250W ATX unit fit alongside my existing 1U server chassis?

The power supply is a 1U form factor rated at 250W with standard ATX connectors, so it mounts in any 1U bay that accepts an ATX PSU.

How can I confirm the EFAP-S250 is delivering stable power after installation?

Verify the 80PLUS Bronze efficiency rating by measuring input versus output under load, and check that all ATX rails report correct voltages in BIOS or monitoring software.
