Compact 1U ATX PSU

The KHACHIMO SZ-3500U P1G-6300P is a 350W ATX power supply in a 1U form factor built for compact chassis and rackmount systems. It targets builders who need reliable DC-to-DC power delivery where vertical space is at a premium.

Efficiency and standby limits

80 PLUS Gold certification confirms high efficiency at typical loads, reducing waste heat and fan activity. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency for systems that stay in low-power states.

Build and acoustic profile

Resonant LLC topology with DC-to-DC conversion supplies clean, consistent power while reducing coil whine. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation during everyday workloads.
