KHACHIMO 1U 150W ATX Power Supply LWP-F315

SKU CH-8Q3E-X9AWW

A 1U 150 W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and LLC resonant topology for clean, quiet power

  • TypeATX
  • Faster wake-from-sleep and better low-load efficiency with Modern Standby compatibility
  • Lower power consumption, less noise and cooler running thanks to 80 PLUS Gold certification
  • Near-silent operation at low and medium loads because the fan stops completely in Zero RPM mode
  • Clean, consistent power delivery and reduced coil whine from Resonant LLC topology with DC-to-DC conversion
  • Compact 1U form factor delivers 150 W ATX power for space-constrained builds

150W 1U ATX power supply for compact builds

This 1U form-factor unit delivers 150 watts of continuous power through a standard ATX connector layout. It targets small-form-factor PCs, thin clients or embedded appliances where vertical space is limited but full ATX pin-outs are still required. The 80 PLUS Gold rating confirms high efficiency across typical load ranges.

Standard ATX mounting with short cable reach

Installation follows normal ATX screw patterns, so the unit drops into any chassis cut for a 1U supply. Cable lengths are optimised for shallow enclosures; in deeper cases the 24-pin, CPU or peripheral leads may fall short of the motherboard headers. Plan routing before securing the unit and verify connector reach against your specific board layout.

Steady output with fan-less idle and Gold efficiency

Under sustained load the resonant LLC topology with DC-to-DC conversion maintains tight voltage regulation while keeping ripple low. The Zero RPM fan mode stops the fan completely at low and medium loads, eliminating acoustic noise during idle or light workloads. Modern Standby compatibility allows the supply to enter and exit low-power sleep states quickly without voltage droop. Efficiency remains high throughout the curve, reducing waste heat in enclosed 1U environments.

Questions about this item

How do I verify the 80 PLUS Gold efficiency is active after installation?

Monitor power draw at the wall under typical load; the unit should run cool and the fan will stay off at low and medium loads thanks to Zero RPM mode.

Which cables and connectors are included with the LWP-F315 and what must I source separately?

The supply ships with the fixed ATX cables needed for a standard build; any proprietary or extra-long cables for special cases must be purchased separately.

Should I choose the 150 W, 320 W, 330 W or 400 W variant for my 1U chassis?

Select the wattage that matches your total component draw plus headroom; the 150 W model suits low-power CPUs and no discrete GPU, while higher ratings support more demanding configurations.
