300 W ATX power supply

This KHACHIMO ACE-A130B-R10 is a 300 W ATX unit built for modern standby PCs that need fast wake times and high efficiency. It targets office desktops, compact builds and quiet workstations rather than high-end gaming rigs or multi-GPU stations.

Installation and common issues

The standard ATX form factor fits most cases with a conventional PSU bracket and uses a single 24-pin motherboard connector plus the usual peripheral leads. Builders sometimes forget to enable modern standby in the BIOS, which prevents the fast wake feature from working as intended.

Pre-order checklist

Verify that your motherboard supports modern standby and that the 300 W output covers the combined draw of your CPU, GPU and drives. Confirm the case accepts a standard ATX supply and that the cable lengths reach every connector without strain.

商品問答

How do I confirm the power supply is running normally after installation?

The fan will stay off at low and medium loads because of the Zero RPM mode; if the system powers on and wakes from sleep almost instantly, the Modern Standby compatibility is working as intended.

What cables come attached and what must I source separately?

All cables are fixed to the unit; the box contains the power supply, mounting screws and an AC power cord, so no modular cables need to be purchased.

Is the 300 W Gold-rated ATX model the right choice for my build?

Choose this 300 W unit if your components draw less than 300 W and you want 80 PLUS Gold efficiency, silent Zero RPM operation and Modern Standby support in a standard ATX form factor.
