KHACHIMO X3500 M4 900W Power Supply

The KHACHIMO X3500 M4 is a 900W ATX power supply built for modern desktop systems. It carries 80 PLUS Gold certification for high efficiency and lower running temperatures. Modern Standby compatibility enables extremely fast wake-from-sleep times. A Zero RPM fan mode stops the fan at low and medium loads for near-silent operation.

Ideal for efficient quiet builds.

This unit suits builders who want high efficiency, quiet operation and fast sleep-state recovery in a standard ATX form factor. The LLC resonant topology with DC-to-DC conversion delivers clean power and reduced coil whine. It is not designed for hot-swap redundant configurations or server backplanes that require multiple coordinated units. Buyers needing N+1 redundancy should look elsewhere.

900W Gold ATX with Zero RPM and Modern Standby

The 900W rated output combined with 80 PLUS Gold certification is the specification that decides fit for most high-performance desktop builds. Zero RPM fan mode and Modern Standby support define the acoustic and idle behaviour. Resonant LLC topology with DC-to-DC conversion ensures stable voltage regulation. Match these traits to your component power budget and noise requirements.

Questions about this item

How can I confirm the X3500 M4 is delivering 900 W reliably after installation?

Monitor system stability under load and check that the fan remains off at idle, indicating Zero RPM mode and 80 PLUS Gold efficiency are active.

What cables and accessories come with the FSA027 unit, and what must I source separately?

The power backplane ships alone; you will need to purchase compatible ATX cables, mounting screws and any GPU or CPU power leads required by your build.

Which part number — 94Y8107, 94Y8108, 69Y5791 or 69Y5792 — matches the 900 W X3500 M4 I need?

All four numbers reference the same 900 W FSA027 model; choose the one listed by your system vendor or chassis manual for guaranteed fit.
