350W ATX Power Supply for Modern Standby Systems

The KHACHIMO FSP350-60AGBAK is a new 350W ATX power supply built for PCs that use Modern Standby sleep states. Its 80 PLUS Gold certification ensures high efficiency, lowering power draw and heat output. The unit targets builders who want quiet, efficient power for compact or low-wattage systems. It is not suited for builds that demand higher continuous output or multiple high-end graphics cards.

80 PLUS Gold Efficiency with LLC Resonant Topology

The single deciding specification is the 80 PLUS Gold rating combined with resonant LLC topology and DC-to-DC conversion. This design delivers clean, consistent power while reducing coil whine and enabling deeper, more energy-efficient sleep states. If your build requires this efficiency tier and topology for stable low-load behaviour, this unit matches; if you need a different efficiency standard or higher wattage headroom, it does not.

Zero RPM Fan and Modern Standby Integration

At low and medium loads the fan stops completely, providing near-silent operation during idle or light tasks. Modern Standby compatibility allows extremely fast wake-from-sleep times and better low-load efficiency. The ATX form factor fits standard chassis layouts, while the efficient topology frees up thermal headroom inside the case. Ensure your motherboard supports Modern Standby to use the fast wake feature.
