KHACHIMO 350W ATX power supply PSB350M-J1

350 W ATX power supply for compact builds

This 350 W ATX unit fits standard mounting points and delivers the 80 PLUS Gold efficiency rating. It supports Modern Standby so systems wake from sleep almost instantly while drawing minimal power at idle. The CRPS form factor suits space-constrained chassis where a full-length PSU would not fit.

CRPS module design frees up case space

Because the supply uses the CRPS module format, it occupies less depth than a traditional ATX brick, leaving extra room for cable routing or a longer graphics card. Zero RPM fan mode stops the fan completely at low and medium loads, removing acoustic noise during office work or media playback. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight and reduces coil whine.

Ideal for small-form-factor PCs needing quiet Gold

Builders who want a short, efficient supply with silent low-load operation will appreciate the zero-fan behaviour and Modern Standby support. Users requiring more than 350 W for high-end multi-GPU configurations or heavy overclocking should look at higher-capacity units. Those needing a conventional full-length ATX enclosure rather than a CRPS module should choose a different form factor.
