KHACHIMO 28V 250W ATX Power Supply

Modern Standby ATX Supply

This 28 V ATX power supply delivers 250 W of continuous output and is built for systems that require Modern Standby compatibility. It carries 80 PLUS Gold certification, so it runs efficiently at typical loads while keeping heat and fan noise low. The resonant LLC topology with DC-to-DC conversion provides clean, stable voltage rails and helps reduce coil whine. It is a new unit suited to compact or low-power builds that rely on fast wake-from-sleep behaviour.

Silent Low-Load Operation

The Zero RPM fan mode stops the fan completely at low and medium loads, giving near-silent running during office work or media playback. Builders who need a quiet, efficient ATX supply for a Modern Standby system will match these features. Buyers who require higher wattage for discrete graphics cards or multi-drive arrays should look at larger-capacity units instead.

28 Volt Output Rail

The defining specification is the 28 V output, which determines whether this supply matches the motherboard or chassis power input requirement. Verify that your platform expects a 28 V ATX source before purchasing, as standard ATX designs typically use different main voltage rails.
