1U 400W Server Power Supply

The KHACHIMO GW-EPS400W is an ATX-type power supply built for 1U server chassis. It delivers 400W of rated output for rack-mounted systems that require a compact form factor. This unit suits integrators assembling dense compute nodes or replacing failed modules in existing racks. It is not for builders needing higher wattage or redundant configurations.

Thermals Noise and Power Draw

The supply operates within standard ATX voltage tolerances for typical server workloads. Its 1U profile relies on internal airflow directed by the chassis fans rather than a large dedicated cooler. Acoustic output will vary with the host system's fan curve and inlet temperature. The unit was first listed by the manufacturer in 2024.

Sustained Load Behaviour

Under continuous demand the supply maintains its rated 400W output as specified by the ATX design. Stable voltage regulation depends on adequate case airflow across the unit's heatsinks. The supplier confirms each unit is test working before shipment. Buyers needing hot-swap redundancy or 24/7 fault tolerance should verify platform support separately.

Questions about this item

How do I install the KHACHIMO 1U 400W GW-EPS400W ATX power supply in a server rack, and what step is commonly missed?

Slide the 1U unit into the rack chassis, secure it with the mounting screws, then connect the 24-pin ATX and CPU power cables; the step often missed is locking the cable retention clips.

What maintenance will the KHACHIMO 1U 400W GW-EPS400W need after extended operation?

Clean the intake fan and heatsink fins with compressed air every few months to prevent dust build-up that reduces cooling efficiency.

Which limit appears first when the KHACHIMO 1U 400W GW-EPS400W runs at full load continuously?

The 400 W output ceiling is reached before thermal protection engages, so sustained draw above that rating will trigger shutdown.
