KHACHIMO 15.7V 4A ATX Power Supply

This KHACHIMO ATX power supply delivers 15.7V at 4A for compatible EFORE systems. It is built new and carries 80 PLUS Gold certification for high efficiency. The unit uses resonant LLC topology with DC-to-DC conversion to provide clean, consistent power. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency.

Suits builders needing Gold efficiency

The zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion reduces coil whine and supports energy-efficient sleep states. It is not for systems requiring a different output voltage or current rating. It is not for builds that lack ATX form-factor clearance.

15.7V 4A fixed output

The power supply provides a fixed 15.7V 4A output designed for specific EFORE compatibility. Verify that the target device matches this exact voltage and current before purchase. The 80 PLUS Gold rating confirms high efficiency across typical loads. No other output rails or voltages are specified in the product data.

Questions about this item

What is the first limit reached under sustained load with the 80 PLUS Gold efficiency rating?

The 80 PLUS Gold certification ensures high efficiency, lowering power consumption and heat, so thermal limits are reached later during sustained use.

How does the Zero RPM Fan Mode affect noise and heat during all-day operation?

At low and medium loads the fan stops completely, giving near-silent running and cooler temperatures thanks to the 80 PLUS Gold efficiency.

Which ATX motherboard connector is required for the Modern Standby compatibility to function?

A motherboard with an ATX power connector that supports Modern Standby is needed for the fast wake-from-sleep and low-load efficiency features.
