330W ATX power supply

The KHACHIMO PW-330ATXE-12V is a 330W ATX power supply built for compact or low-power desktop builds. It suits office workstations, home-theatre PCs or basic productivity rigs that do not demand high-wattage graphics cards. The unit carries 80 PLUS Gold certification for high efficiency at typical loads. Buyers who want more headroom for discrete GPUs or heavy overclocking should look elsewhere.

ATX form factor with Modern Standby support

Its standard ATX dimensions let it drop into most mid-tower and mini-tower chassis without adapter brackets. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine. Builders needing non-ATX form factors such as SFX or TFX cannot use this unit.

Sustained load behaviour

The 80 PLUS Gold rating means the supply maintains high efficiency during prolonged operation, lowering power draw and heat output. Zero RPM fan mode keeps the fan off at low and medium loads for near-silent running, spinning up only when thermal demand rises. This combination helps the unit run cooler and quieter over long sessions. No liquid-cooling support or redundant configuration is provided.

Questions about this item

How much continuous power can the 330W unit deliver before protection triggers?

The supply is rated for 330 W of continuous output; its over-power protection will activate if that limit is exceeded.

Does the fan stay off during an all-day workload?

Zero RPM Fan Mode stops the fan at low and medium loads, while 80 PLUS Gold efficiency keeps heat low enough that the fan often remains off for typical all-day use.

Will this ATX power supply fit my existing case and motherboard?

It uses the standard ATX form factor and 12 V DC-to-DC design, so it fits any ATX case and works with modern motherboards that have a 24-pin main connector and 4-pin or 8-pin CPU power.
