600W ATX Power Supply for Modern Standby PCs

The KHACHIMO PSM-6600P delivers 600W of continuous power through a standard ATX form factor. It targets system builders who want 80 PLUS Gold efficiency and quiet operation in a new desktop or workstation. The unit supports Modern Standby for rapid wake-from-sleep transitions.

Gold efficiency limits heat

The 80 PLUS Gold rating guarantees high efficiency across the load range, which reduces waste heat and keeps fan speeds lower. Zero RPM mode stops the fan completely at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion further cuts coil whine and supports deeper sleep states.

Modern Standby support decides fit for fast-wake

This supply is built for Modern Standby compatibility, enabling extremely fast wake times and better low-load efficiency. If your motherboard and OS do not use Modern Standby, the fast-wake benefit is not realised. Builders without that requirement may prefer a simpler unit.
