Rectangular ATX power supply unit in matte black finish with 80 PLUS Gold badge

KHACHIMO

KHACHIMO 150W ATX Power Supply 48V 55V 80 PLUS Gold

SKU CH-CCKW-Z5GWP

ATX power supply delivering 150 W at 48 V or 55 V with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and resonant LLC topology with DC-to-DC conversion

  • TypeATX
  • Faster wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Fan stops at low loads for silent running
  • LLC resonant plus DC-to-DC topology delivers clean power
  • Dual 48 V and 55 V output options

Purpose and compatibility

This 150 W ATX power supply delivers a 48 V or 55 V DC output for specialised industrial or embedded systems that require a single high-voltage rail. It is intended for builders who need a direct replacement for the referenced TDK-Lambda HWS150 series units.

Thermals noise and power draw

The 80 PLUS Gold certification confirms high efficiency across typical loads, reducing waste heat and overall power consumption. A Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent operation, while the resonant LLC topology with DC-to-DC conversion minimises coil whine and supports efficient sleep states.

Build quality and connectors

Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency for systems using deeper sleep states. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power delivery and reduces coil whine. No modular cabling or standard ATX peripheral connectors are described in the supplied data.

Questions sur cet article

How do I install the KHACHIMO 150W ATX power supply and which cable routing step is often missed?

Mount the unit in the case using the four ATX screws, connect the 24-pin motherboard and 4/8-pin CPU cables, then route all cables behind the motherboard tray before securing the side panel — skipping the rear routing step blocks airflow and makes future upgrades harder.

What maintenance will this 80 PLUS Gold 150W unit need over its lifespan?

Clean dust from the intake grill every six months with compressed air; the Zero RPM fan mode means the fan spins less often, so bearings last longer, but the grill still collects debris that reduces cooling efficiency at 48V or 55V loads.

At what point does the 150W limit appear first during sustained high-load operation?

The 150W continuous rating is the first ceiling — pushing the 48V or 55V rails beyond 150W triggers over-power protection and shuts the unit down, so total system draw must stay under that figure during extended workloads.
