280W ATX Gold Power Supply

The KHACHIMO 280W ATX power supply delivers 80 PLUS Gold certified efficiency in a standard ATX form factor. It is built for desktop systems that require reliable, energy-efficient power with modern standby support for instant wake times. This unit suits compact or office builds where low noise and cool operation are priorities.

Best for quiet, efficient desktops.

Builders who value near-silent operation will benefit from the Zero RPM fan mode that stops the fan at low and medium loads. The resonant LLC topology with DC-to-DC conversion reduces coil whine and supports efficient sleep states. Systems needing significantly more than 280 W of continuous power should look at higher-capacity units instead.

80 PLUS Gold efficiency at 280 W

The 80 PLUS Gold rating confirms high efficiency across typical loads, lowering electricity use, heat output and acoustic noise. Modern Standby compatibility enables extremely fast wake-from-sleep performance. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power delivery for stable operation.

Questions about this item

What ATX form factor does the KHACHIMO 280W unit use so I know it fits my case?

It follows the standard ATX layout, so it mounts in any case designed for a regular ATX power supply.

Which cables must be connected first during installation to avoid a no-post issue?

Seat the 24-pin motherboard connector and the 4+4-pin CPU power cable firmly before routing any peripheral leads.

How often should the 80 PLUS Gold fan be cleaned to keep Zero RPM mode working?

Blow dust from the fan grille every six to twelve months; a clogged fan prevents the Zero RPM mode from engaging at low load.
