  • 250 W ATX supply fits compact 1U systems

Compact ATX power supply

The KHACHIMO ENH-0625A ENH-0620A is a 250 W ATX power supply built in a small standard 1U form factor. It carries 80 PLUS Gold certification and uses resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation.

Suited for space-constrained builds

This unit fits small-form-factor and 1U systems that need an ATX-compatible supply with Gold-rated efficiency and quiet running. It is not for builds that demand more than 250 W of continuous power. It is not for configurations requiring multiple high-power graphics cards or large numbers of drives. It is not for users who need modular cabling or a standard ATX-depth chassis fit.

The 250 W rating decides fit

The single specification that determines whether this is the right part is the 250 W maximum output. If the total system draw under load stays below this figure, the supply will handle it with Gold efficiency and silent low-load behaviour. If the build needs more headroom, a higher-wattage unit must be chosen.

Questions about this item

What clearance is required for the 1U form factor of this ATX power supply?

The unit is a 1U design, so it fits standard rack or slimline chassis slots that accept a single rack-unit height.

How do you enable Modern Standby support on the KHACHIMO ENH-0625A?

Connect the ATX power cables to a motherboard that implements Modern Standby; the supply’s resonant LLC topology and DC-to-DC conversion then handle the low-power sleep states automatically.

When should the cooling fan be cleaned or replaced on this 250W unit?

The Zero RPM Fan Mode stops the fan at low and medium loads, so dust buildup is slower; inspect during routine system cleaning and replace only if noise or vibration appears.
