What this power supply is

The KHACHIMO M1Z-5500V is a new 500W ATX switching power supply built for desktop PCs. It carries 80 PLUS Gold certification and uses resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power while enabling modern sleep states. Modern Standby compatibility ensures extremely fast wake-from-sleep times and better low-load efficiency.

Who this suits and who it does not

This unit suits builders who want high efficiency, low noise and support for modern standby sleep states in a standard ATX form factor. The zero-RPM fan mode stops the fan entirely at low and medium loads for near-silent operation. Buyers who need more than 500W of continuous output, redundant power modules or server-grade hot-swap capability should look at other products.

The deciding specification

The single specification that decides whether this is the right part is the 500W rated output combined with 80 PLUS Gold certification. This pairing defines the power ceiling and efficiency class for any ATX build considering this supply.

Questions about this item

How can I confirm the 80 PLUS Gold efficiency is active after installing the 500W unit?

The PSU carries 80 PLUS Gold certification; verify operation by checking that the fan remains off under light load thanks to Zero RPM Fan Mode and that wake-from-sleep is near-instant with Modern Standby.

What cables and accessories are included with the M1Z-5500V and what must I source separately?

The box contains the ATX power supply unit; all modular cables, mounting screws and any adapter leads need to be purchased separately.

Which capacity should I choose for a build that needs 500W continuous power?

The M1Z-5500V is the 500W model and is the only capacity offered in this series.
