KHACHIMO M1S-3400V 400W ATX Power Supply

This new ATX power supply delivers 400W of continuous power for desktop builds. It carries 80 PLUS Gold certification for high efficiency and lower running costs. The unit targets system integrators and upgraders who need reliable, efficient power in a standard form factor.

80 PLUS Gold efficiency and Modern Standby support

The single specification that decides fit is the 80 PLUS Gold rating combined with Modern Standby compatibility. This ensures high efficiency across typical loads and enables extremely fast wake-from-sleep times with better low-load efficiency. Builds requiring basic Bronze efficiency or lacking Modern Standby hardware will not benefit from these specific features.

400W capacity with quiet operation headroom

The 400W output comfortably handles mainstream CPUs and mid-range graphics cards under full load. Zero RPM fan mode keeps the unit silent at low and medium loads, while resonant LLC topology with DC-to-DC conversion reduces coil whine. Systems demanding sustained loads above 400W or multi-GPU configurations will exceed the available headroom.

Perguntas sobre este artigo

What does the 80 PLUS Gold rating mean for daily power draw?

It certifies the unit meets 80 PLUS Gold efficiency targets, so less electricity is wasted as heat and the system runs cooler.

How does the ATX form factor limit where this 400 W supply can be installed?

The ATX design fits standard ATX cases and motherboards, so it works in any chassis built for that layout.

What clearance or mounting points does the M1S-3400V need inside the case?

It uses the standard four-screw ATX mounting pattern and requires the usual rear cut-out and internal depth for a typical ATX unit.
