Server-ready 300W ATX power

The KHACHIMO PSA300M-J2 is a 300W ATX redundant supply built for server chassis that require continuous uptime. It fits standard ATX bays and supports Modern Standby for rapid wake-from-sleep cycles.

80 PLUS Gold efficiency headroom

Gold certification means the unit runs efficiently at typical server loads, reducing waste heat and fan noise. At 300W it comfortably powers single-socket platforms with modest storage arrays; multi-GPU or heavily populated drive cages will exceed its output.

Zero RPM fan and LLC topology benefits

The resonant LLC design with DC-to-DC conversion delivers clean voltage rails and suppresses coil whine. Zero RPM mode stops the fan entirely at low and medium loads, giving near-silent operation during idle or light background tasks.

Questions about this item

Will this 300W redundant unit fit and power an older ATX chassis I already own?

Yes, the ATX form factor matches standard cases and the 300W output covers typical legacy builds.

How can I confirm the Zero RPM Fan Mode is active after installation?

Under light loads the fan stops spinning completely; listen for silence or watch the fan blades through the grille.

Does the box include every cable needed for a standard ATX build, or must I buy extras?

The unit ships with all fixed ATX cables attached; no additional cables are required for a typical installation.
