KHACHIMO ATX Power Supply 80 PLUS Gold 3591

ATX Power Supply for Liteon PS-3591-1

This new ATX power supply is built as a direct replacement for the Liteon PS-3591-1 unit. It fits standard ATX layouts and supports Modern Standby for rapid wake-from-sleep responsiveness. The 80 PLUS Gold certification confirms high efficiency across typical loads. It suits system builders and repair technicians who need a reliable, efficient power source for compatible desktop chassis.

Zero RPM Fan Mode and Resonant LLC Topology

A Zero RPM fan mode stops the cooling fan completely at low and medium loads, delivering near-silent operation during idle or light tasks. The resonant LLC topology with DC-to-DC conversion supplies clean, consistent power while reducing coil whine. These features also enable more energy-efficient sleep states, lowering overall power draw when the system is not under heavy demand.

ATX Form Factor and Modern Standby Connectivity

The standard ATX form factor ensures straightforward mounting in compatible cases using existing screw points. Modern Standby compatibility means the power supply works with motherboards that support ultra-fast sleep and wake transitions. Connectors follow the ATX pinout required by the PS-3591-1 design, so installation proceeds without adapter cables or non-standard wiring. Builders who need a different form factor or higher wattage than the original unit provides should verify specifications before purchase.
