KHACHIMO ATX Power Supply YMFEV-1050XIXB 14.5V 2.1A 3.6A 80 PLUS Gold

ATX Power Supply with Modern Standby

The KHACHIMO ATX unit delivers 14.5V at 2.1A and 3.6A rails with 80 PLUS Gold certified efficiency. It is built for systems that require fast wake-from-sleep transitions and low-load energy savings. The resonant LLC topology with DC-to-DC conversion supplies clean power while reducing coil whine. This new component suits builders who prioritise quiet, efficient operation in compatible desktop chassis.

Suitable for Modern Standby PCs.

This supply fits computers that support Modern Standby sleep states and benefit from zero-RPM fan silence at typical loads. It is not intended for configurations demanding higher total output or multiple high-current rails beyond the rated 2.1A and 3.6A limits. Buyers needing greater headroom for multi-GPU arrays or extreme overclocking should look at higher-capacity units. The gold-rated efficiency helps keep thermals low in standard productivity or home-office machines.

Standard ATX installation with fan-curve awareness

Mounting follows the usual ATX screw pattern and connector layout, so most builders can swap it in without special tools. The zero-RPM mode engages automatically at low and medium loads, meaning the fan may stay still during idle or light work — this is normal, not a fault. Ensure case airflow can handle passive cooling when the fan is off. Coil whine is minimised by the LLC design, but sensitive ears in silent rooms may still detect faint noise at certain load points.
