Compact 280W ATX power unit

This 280W ATX supply targets small-form-factor and office builds that need reliable power without the bulk of higher-wattage units. It suits system integrators and home users assembling compact desktops for everyday productivity.

Gold efficiency with silent fan profile

80 PLUS Gold certification reduces waste heat and keeps noise low under typical loads. A Zero RPM fan mode stops the fan completely at low and medium loads, while Modern Standby support enables rapid wake-from-sleep and deeper sleep states.

Headroom for modest CPUs and integrated graphics

The 280W rating comfortably handles mainstream processors and integrated graphics in daily workloads. Discrete graphics cards or high-core-count CPUs will exceed the available power budget, making this unit unsuitable for gaming or workstation builds.

Questions about this item

When will the cooling fan need replacement on the KHACHIMO 280W ATX unit?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, reducing wear so the fan typically lasts the life of the power supply.

What limits output first during sustained load on this 280W model?

The 280 W rated capacity is the hard ceiling; once total draw reaches that level the protection circuits will shut the unit down.

How much noise and heat appear when the 80 PLUS Gold supply runs all day?

At low and medium loads the fan stays completely off for silent operation, while Gold efficiency keeps waste heat and power draw low.
