Modern Standby Compatible 725W ATX Power Supply

The KHACHIMO C20 C20X is a 725W ATX power supply built for modern desktop PCs that use low-power sleep states. It suits builders who need reliable output for mainstream components and want fast wake-from-sleep performance. It is not for systems that require higher peak wattage or server-grade redundancy.

80 PLUS Gold Efficiency Limits

The unit carries 80 PLUS Gold certification, meaning it meets defined efficiency targets at typical loads to reduce waste heat and fan noise. Efficiency drops at very light or very heavy loads, so the practical benefit depends on how the system is used day to day. The Gold rating does not guarantee silent operation under sustained maximum output.

Zero RPM Fan Mode and LLC Topology

A Zero RPM mode stops the fan completely at low and medium loads, while the resonant LLC topology with DC-to-DC conversion aims to deliver clean power and reduce coil whine. Installation follows standard ATX mounting and cabling; the main issues arise if the case lacks clearance for the unit's depth or if the motherboard lacks Modern Standby support, leaving the fast-wake feature unused.
