Compact 1U silver ATX power supply unit with rear fan grille and cable bundle

KHACHIMO

KHACHIMO GW-FLX250M 250W ATX power supply

SKU CH-X5TX-VWCXR

A 250W ATX power supply with 80 PLUS Gold efficiency, Modern Standby support, Zero RPM fan mode, and resonant LLC topology with DC-to-DC conversion for clean power and quiet operation

  • TypeATX
  • Modern Standby support enables rapid wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency for lower consumption, less noise and cooler running
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine
  • 250 W ATX output in a compact 1U flex form factor fits space-constrained builds

Compact ATX supply for small-form-factor builds

The KHACHIMO GW-FLX250M is a 250 W ATX power supply built for 1U and other space-constrained chassis. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion to deliver clean power with low ripple and reduced coil whine. Modern Standby support enables rapid wake-from-sleep transitions and improved efficiency at light loads. A zero-RPM fan mode keeps the unit silent during low and medium workloads.

Upgrade from lower-efficiency flex units

Replacing an older non-modular flex-ATX supply rated below Gold efficiency will cut idle power draw and system heat while adding Modern Standby compatibility for faster sleep recovery. The jump is worthwhile when the existing unit lacks DC-to-DC conversion, produces audible coil whine, or cannot sustain stable voltages on modern low-power sleep states. Builders moving to a newer platform that demands tighter voltage regulation will also benefit.

Suited for slim desktops and quiet workstations

This unit fits compact office PCs, home-theatre systems and silent workstations where a 1U form factor and semi-passive cooling are priorities. It is not intended for builds that require more than 250 W of continuous power, such as discrete-graphics gaming rigs or workstations with multiple high-current drives. Buyers needing higher wattage, modular cables or redundant power should look at larger form-factor supplies.

商品問答

Will the 1U height fit my compact server chassis?

The unit is a 1U form factor, so it occupies a single rack unit in standard server or workstation enclosures.

Which cables do I connect for Modern Standby support?

Use the 24-pin ATX connector and the 4+4-pin EPS connector; the PSU handles the low-power signalling required for Modern Standby automatically.

How often should I clean the fan to keep Zero RPM mode working?

Remove dust from the intake and exhaust vents every six to twelve months; a clogged heatsink raises temperatures and prevents the fan from staying off at low load.
