Compact ATX power supply

The KHACHIMO SO-350PSU is a 300W ATX unit built for small-form-factor and 1U systems where space is tight. It suits builders assembling slim desktops, embedded appliances or quiet office rigs that need reliable power without a full-height chassis.

Fits 1U layouts and modern sleep states

Its short depth lets it slide into 1U enclosures while the Modern Standby support enables extremely fast wake-from-sleep and better low-load efficiency. The DC-to-DC design with resonant LLC topology delivers clean power rails and frees the builder from hunting for legacy group-regulated units.

Quiet, efficient delivery under sustained load

80 PLUS Gold certification means high efficiency across the load range, reducing waste heat and keeping internal temperatures lower. The Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running, while the resonant LLC topology suppresses coil whine during extended sessions.

Perguntas sobre este artigo

How does the 80 PLUS Gold rating affect power draw and heat when the PSU runs all day?

The 80 PLUS Gold certification means high efficiency operation, which lowers power consumption, reduces noise and keeps temperatures cooler during continuous use.

At what load does the Zero RPM fan mode stop and the fan start spinning?

The cooling fan switches off entirely at low and medium loads for near-silent operation, then activates only when the load increases beyond that range.

Which motherboard power connectors does the ATX unit include for a standard build?

As an ATX power supply it provides the standard 24-pin main connector and the 4-pin or 8-pin CPU power connector required by modern motherboards.
