SFX 300W power supply for compact builds

This SFX form-factor unit delivers 300 W of continuous power for small-form-factor PCs and HTPCs. Its 80 PLUS Gold certification ensures high efficiency across typical loads, reducing heat output and electricity draw. The supply suits builders who need reliable power in space-constrained chassis.

Fits SFX bays and enables modern standby

The SFX footprint matches standard SFX mounting brackets, so it installs directly in compatible cases without adapters. Modern Standby compatibility allows the system to wake from sleep almost instantly while maintaining low idle power. Resonant LLC topology with DC-to-DC conversion delivers clean voltage regulation for stable operation.

Zero RPM fan mode and gold efficiency included

A semi-passive fan profile stops the fan completely at low and medium loads, eliminating noise during light work. The 80 PLUS Gold rating confirms the unit meets strict efficiency targets without extra accessories. No additional cables or software bundles are mentioned in the specifications.

Questions about this item

What limits the KHACHIMO SFX 300W under sustained full load?

The 300 W rating is the maximum continuous power the unit can deliver, so sustained demand above that level will trigger protection and shut the system down.

How does the power supply handle noise and heat during all-day operation?

Zero RPM mode stops the fan completely at low and medium loads for silent running, while 80 PLUS Gold efficiency reduces waste heat so the fan spins less often even under load.

What must the buyer already have for this SFX unit to work in their build?

An SFX-compatible case and a motherboard with a standard 24-pin ATX power connector, plus the necessary CPU and peripheral cables for the components being powered.
