KHACHIMO

KHACHIMO Power Supply 600W 12V 24V 80 PLUS Gold

SKU CH-45QR-ZVMKV

A 600W ATX power supply with 12V and 24V outputs, 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and resonant LLC topology with DC-to-DC conversion

  • TypeATX
  • Modern Standby support for near-instant wake from sleep
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Zero RPM fan mode stops the fan at low load
  • Resonant LLC with DC-to-DC gives clean, stable output
  • 600 W capacity on 12 V and 24 V rails

Replacement for TDK-Lambda CWS600S1

This 600 W ATX power supply is built as a direct replacement for the TDK-Lambda CWS600S1 series, matching the 12 V and 24 V output variants used in industrial and workstation chassis. It suits technicians and system integrators who need a drop-in unit that keeps existing wiring and mounting points intact.

80 PLUS Gold Efficiency and Load Behaviour

The 80 PLUS Gold rating means the unit runs at high efficiency across typical loads, reducing waste heat and fan activity. At low and medium loads the Zero RPM mode stops the fan completely, so acoustic output drops to near zero until the thermal load demands active cooling.

Resonant LLC Topology with DC-to-DC

A resonant LLC primary stage paired with DC-to-DC secondary regulation delivers tight voltage regulation and low ripple, which also minimises coil whine. Modern Standby support allows the supply to enter and exit low-power sleep states quickly, a requirement for current desktop platforms that rely on fast wake times.

Questions about this item

Will the 600 W unit power my older ATX motherboard without cable mismatches?

The supply follows the ATX form factor and delivers 12 V and 24 V rails, so it connects to standard ATX boards and legacy peripherals that use those voltages.

How can I confirm the Zero RPM fan mode is active after I build the system?

At low and medium loads the cooling fan switches off entirely; you will hear no fan noise and the 80 PLUS Gold efficiency keeps temperatures down while the system idles.

Does the box include every cable I need for a typical ATX build or must I buy modular leads separately?

The unit is a fixed-cable ATX power supply; all mainboard, CPU and peripheral leads are attached, so no extra modular cables are required.
