ATX Power Supply for Modern Standby Systems

The KHACHIMO SSH-250G is a 250W ATX unit built for desktops that use Modern Standby sleep states. Its 80 PLUS Gold certification ensures high efficiency across typical loads, reducing waste heat and electricity draw. This makes it a suitable choice for compact or energy-conscious builds that prioritise low idle power.

Resonant LLC Topology with DC-to-DC Conversion

The platform uses a resonant LLC design paired with DC-to-DC conversion to deliver clean, consistent voltage rails and minimise coil whine. A Zero RPM fan mode stops the cooling fan completely at low and medium loads, providing near-silent operation during everyday tasks. These features support the deeper, more efficient sleep states enabled by Modern Standby compatibility.

Replacing Older Low-Wattage ATX Units

This supply upgrades legacy 250W-class units that lack Gold efficiency or Modern Standby support. The jump is worthwhile when a system requires fast wake times, quieter fan behaviour, and tighter voltage regulation for modern low-power components. It is not for builds needing higher total wattage or auxiliary connectors beyond what a 250W ATX design provides.

Questions about this item

Does the 80 PLUS Gold rating limit how much power the KHACHIMO AT P8P9 SSH-250G can deliver continuously?

The 80 PLUS Gold rating certifies high efficiency at typical loads; the continuous output limit is the 250 W rating stated for the unit.

What physical space and mounting points does the KHACHIMO AT P8P9 SSH-250G require inside a case?

It follows the standard ATX form factor, so it fits any chassis with an ATX power-supply bay and uses the usual four rear mounting screws.

Which cables must be connected during installation, and what is the common mistake?

Connect the 24-pin ATX motherboard cable and the 4/8-pin CPU power cable; the frequent error is forgetting the CPU power connector, which prevents the system from posting.
