Compact 1U ATX power supply

The KHACHIMO FSP250-50 is a 250 W ATX unit built in a 1U form factor. It targets system integrators and IT professionals who need a reliable power source for rack-mount or space-constrained chassis. Each unit is supplied new and test-working to verify basic operation before deployment.

250 W capacity and typical headroom

This supply delivers a maximum of 250 W, which comfortably handles low-power CPUs, integrated graphics and a modest complement of drives or expansion cards. Headroom diminishes quickly when discrete GPUs, multiple storage arrays or high-core-count processors are added, so the unit is best suited to office, edge or thin-client workloads.

ATX interface limits in a 1U package

The ATX connector set fits standard motherboards, yet the 1U height restricts internal cooling airflow and total power density compared with full-height units. Builders must confirm that their chassis can route the fixed cables and that the 250 W ceiling matches the complete system draw under sustained load.

Questions about this item

Will the FSP250-50 fit and power an older 1U server chassis that uses a standard ATX connector?

The unit is an ATX type supply rated at 250 W and built in a 1U form factor, so it matches the power connector and physical slot of legacy 1U systems that expect a standard ATX pin-out.

How can I verify the FSP250-50 is delivering stable power once installed?

The manufacturer highlights that each unit is test working before dispatch; after installation, check that the system boots reliably and monitor voltage rails in the BIOS or with a hardware monitor to confirm they remain within ATX tolerance.

What comes with the FSP250-50 and what must I source separately?

The package contains the 250 W 1U power supply itself; mounting screws, a power cord and any additional cables required by your specific chassis are not included and must be purchased separately.
