KHACHIMO MATX 250W Power Supply

The KHACHIMO MATX 250W Power Supply is a new ATX unit built for compact systems. It delivers 250 watts of continuous power with 80 PLUS Gold certified efficiency. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency.

Upgrading from lower-efficiency units

Replacing a standard bronze or unrated supply with this Gold-certified model cuts power draw and reduces heat output. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine. Zero RPM fan mode keeps the system near-silent at low and medium loads.

Ideal for small-form-factor builds

This unit suits builders assembling MATX or space-constrained PCs that need reliable 250 watt delivery and quiet operation. Buyers requiring higher wattage for discrete graphics cards or multi-drive arrays should look at larger capacity power supplies.
