KHACHIMO 40W ATX power supply unit with fan grille

KHACHIMO

KHACHIMO 40W 1.5V 6A 2.12V 2A ATX power supply

SKU CH-J1T2-0HRJK

ATX power supply delivers 40 W with 1.5 V 6 A and 2.12 V 2 A rails, 80 PLUS Gold efficiency, zero-RPM fan mode and LLC resonant topology for silent, efficient operation

  • TypeATX
  • Faster wake-from-sleep with Modern Standby support
  • Lower electricity draw thanks to 80 PLUS Gold efficiency
  • Near-silent operation at low loads via Zero RPM fan mode
  • Cleaner power delivery using resonant LLC topology with DC-to-DC conversion
  • Supports efficient sleep states through advanced topology design

Target system

This 40 W ATX power supply delivers 1.5 V at 6 A and 2.12 V at 2 A for the ECM40UD21 platform. It suits builders assembling or servicing small-form-factor PCs that require these specific low-voltage rails.

Build integration

The unit fits standard ATX mounting points and provides the exact voltages the ECM40UD21 board expects without extra adapters. Its 80 PLUS Gold efficiency reduces waste heat, helping keep compact chassis temperatures manageable.

Sustained behaviour

Zero RPM fan mode keeps the supply silent at low and medium loads by stopping the fan completely. Resonant LLC topology with DC-to-DC conversion maintains clean power delivery and supports Modern Standby for rapid wake times during extended use.

Questions about this item

How much continuous power can the 40W unit deliver before its protection limits activate?

The supply is rated for 40W total output across its 1.5V 6A and 2.12V 2A rails, so sustained loads above that will trigger over-power protection.

Does the fan stay off or run quietly during all-day operation at typical loads?

Zero RPM Fan Mode stops the fan completely at low and medium loads, and 80 PLUS Gold efficiency keeps waste heat low for quieter all-day running.

Which motherboard form factor and connector standard must the system already have for this ATX unit to fit?

The chassis and motherboard need a standard ATX power-supply mounting pattern and a 24-pin ATX main connector to accept this unit.
