KHACHIMO Power Supply 57V 5.3A 80 PLUS Gold ATX

SKU CH-RDNV-CYTDQ

An ATX power supply delivering 57 V at 5.3 A with 80 PLUS Gold efficiency, zero-RPM fan mode and resonant LLC topology for quiet, low-heat operation

  • TypeATX
  • Faster wake-from-sleep with Modern Standby support
  • Lower power draw thanks to 80 PLUS Gold efficiency
  • Silent running at low loads via Zero RPM fan mode
  • Clean, stable output from resonant LLC and DC-to-DC design
  • Delivers 57 V at 5.3 A for compatible TDK-Lambda units

Compatible 57 V Replacement Unit

This ATX power supply is built as a direct replacement for TDK-Lambda EVS57-5R3/A modules. It delivers 57 V at 5.3 A and is aimed at technicians or system integrators who need a drop-in unit for compatible industrial or embedded platforms.

Sustained Load Behaviour

The resonant LLC topology with DC-to-DC conversion maintains clean, consistent power delivery during continuous operation. 80 PLUS Gold certification ensures high efficiency across the load range, reducing waste heat and supporting stable voltage regulation over long periods.

Thermals Noise and Power Draw

Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent running. Modern Standby compatibility enables fast wake-from-sleep transitions while keeping low-load efficiency high and overall power consumption reduced.

Questions about this item

How quiet is the 80 PLUS Gold unit under continuous all-day load?

The Zero RPM fan mode stops the fan at low and medium loads for near-silent operation, while the resonant LLC topology with DC-to-DC conversion reduces coil whine for quieter running.

What existing system connector does the ATX power supply require to function?

The unit uses a standard ATX form factor, so it needs a compatible ATX motherboard connector and a mains power cable to operate.

Will the Modern Standby compatible PSU wake older hardware quickly from sleep?

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency when paired with supported platforms.
