SKU CH-C334-NADED

A 650W ATX unit with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and resonant LLC topology with DC-to-DC conversion for clean, quiet power

  • TypeATX
  • Modern Standby support for faster wake-from-sleep and better low-load efficiency
  • 80 PLUS Gold certification for high efficiency, lower consumption and cooler operation
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent running
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine
  • 650W ATX output compatible with TDK-Lambda AlphaII-650 MV6500268A

KHACHIMO 650W ATX Power Supply

This KHACHIMO unit is a 650W ATX power supply built as a direct replacement for the TDK-Lambda AlphaII-650 unit carrying part number MV6500268A. It uses a resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power to a desktop system. The design targets modern standby compatibility for fast wake-from-sleep response and improved low-load efficiency. Gold certification confirms high efficiency across typical operating ranges.

Suitable for modern standby desktops needing quiet

Builders who want near-silent performance at low and medium loads will benefit from the zero RPM fan mode that stops the fan entirely. The resonant LLC design also reduces coil whine for quieter operation overall. Systems that must sustain loads beyond 650W or require a different physical form factor than standard ATX should look at other power supplies. Installations needing specific cable configurations not listed here will need to verify compatibility separately.

The deciding specification is the 650W ATX rating

This power supply delivers 650 watts through a standard ATX form factor, which is the single figure that determines whether it fits the power budget and physical space of the target build. The MV6500268A part number confirms it matches the original TDK-Lambda AlphaII-650 unit. If the system demands more than 650W or uses a non-ATX chassis, this unit will not meet the requirement.
