280 W ATX Power Supply for Modern Standby Systems

This KHACHIMO unit delivers 280 W through a standard ATX form factor. It targets builders assembling compact or office PCs that rely on Modern Standby for instant wake and low idle draw. The Gold-rated platform suits workloads that stay near idle for long periods.

80 PLUS Gold Limits at 280 W

The 80 PLUS Gold rating guarantees high efficiency at typical loads, but the 280 W ceiling restricts use to integrated graphics or low-power discrete cards. Sustained heavy loads will push the unit close to its maximum output, leaving no headroom for future GPU upgrades.

Straightforward ATX Fit with Zero-RPM Idle

Installation follows normal ATX mounting and cabling; the Zero RPM fan mode activates automatically at low and medium loads for silent running. Builders must verify that their case accommodates the PSU length and that the fixed cable set reaches all components without extensions.

Domande su questo articolo

Should I choose the XE 486, 745 or 755 variant of this 280 W unit?

The three part numbers all refer to the same 280 W ATX power supply; pick the one that matches your original part label.

What does the 280 W rating mean once the PSU is installed?

It delivers up to 280 W of continuous power with 80 PLUS Gold efficiency, so typical loads run cooler and draw less from the wall.

It uses an ATX form factor with Resonant LLC topology and DC-to-DC conversion, limiting ripple and enabling Modern Standby sleep states.
