400 W ATX Power Supply for Modern Standby PCs

The KHACHIMO RM-4514-00 delivers 400 W of continuous ATX power and carries 80 PLUS Gold certification. It is built for systems that require Modern Standby compatibility and high efficiency at typical desktop loads. The unit suits builders who want a compact, efficient supply for a mainstream workstation or home office PC.

Sustained load behaviour with Zero RPM fan mode

Under sustained load the resonant LLC topology with DC-to-DC conversion maintains clean, consistent power delivery while reducing coil whine. At low and medium loads the cooling fan stops completely, enabling near-silent operation. The design supports energy-efficient sleep states so the system stays cool and quiet during extended work sessions.

80 PLUS Gold efficiency decides fit

The single specification that determines suitability is the 80 PLUS Gold rating, which guarantees high efficiency for lower power draw, less noise and cooler temperatures. Systems needing more than 400 W or a different efficiency tier will require another unit.

Questions about this item

How much heat and noise does the 400W 80 PLUS Gold unit produce when it runs continuously?

The 80 PLUS Gold certification means high efficiency, so less waste heat and lower fan speeds. At low and medium loads the Zero RPM mode stops the fan completely for near-silent operation.

What cables and connectors must my build already provide for this ATX supply to work?

A standard ATX 24-pin motherboard connector and 4/8-pin CPU power connector are needed; the power supply includes the matching cables.

Will the resonant LLC topology with DC-to-DC conversion cause issues with older components I keep?

The topology delivers clean, consistent power and reduces coil whine, so it works reliably with legacy parts while also supporting modern low-power sleep states.
