KHACHIMO PSM-ISR950EP 350W ATX Power Supply

The KHACHIMO PSM-ISR950EP is a 350W ATX power supply built for modern desktop systems. It carries 80 PLUS Gold certification for high-efficiency operation and supports Modern Standby for extremely fast wake-from-sleep times. The unit uses resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power. It is suited for builds that prioritise low power draw and efficient sleep states.

80 PLUS Gold Efficiency and Zero RPM Fan Mode

Gold-rated efficiency reduces power consumption, lowers heat output and cuts fan noise during typical workloads. The Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion further reduces coil whine and enables more energy-efficient sleep states. These features combine to create a quieter, cooler-running system environment.

Ideal for Efficient Modern Standby Builds

This unit suits builders who want fast wake times, high efficiency and silent operation at modest power levels. It is not for systems that require higher wattage for multi-GPU configurations or heavy overclocking headroom. Buyers needing more than 350W of continuous power should look at higher-capacity models. The ATX form factor fits standard chassis designs without special mounting requirements.

商品問答

Will the fan on the PSM-ISR950EP need replacement after long-term use?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, reducing wear; if replacement is ever needed, it uses a standard ATX fan size.

What limit appears first when the PSM-ISR950EP runs at full 350W output continuously?

The 350W rated capacity is the hard ceiling; sustained loads at that level will hit the power limit before thermal protection engages.

How much heat and noise does the PSM-ISR950EP produce during all-day operation?

80 PLUS Gold efficiency and Resonant LLC topology with DC-to-DC conversion minimise waste heat and coil whine, while Zero RPM mode keeps it near-silent at typical loads.
