KHACHIMO 3.3V 60A 300W ATX power supply

This KHACHIMO ATX power supply delivers 300 watts with a strong 3.3 volt rail rated at 60 amps. It carries 80 PLUS Gold certification for high efficiency and includes Modern Standby support for fast wake times. A Zero RPM fan mode stops the fan at low and medium loads, while a resonant LLC topology with DC-to-DC conversion reduces coil whine.

Suited for compact systems needing high 3.3 volt

This unit fits builds that draw heavily on the 3.3 volt rail and value quiet, efficient operation. It is not for systems that require higher total wattage or multiple dedicated connectors for power-hungry discrete graphics cards.

3.3 volt rail rated at 60 amps

The 3.3 volt rail supplies up to 60 amps, which is the key figure for matching this supply to motherboards and components that depend on that specific voltage. Verifying the 3.3 volt demand of your hardware decides whether this 300 watt unit is the right choice.

Questions about this item

How can I confirm the 300W unit is delivering stable 3.3V output after installation?

Monitor the 3.3V rail in BIOS or hardware-monitoring software; it should read close to 3.3V under load. The 80 PLUS Gold certification and resonant LLC topology with DC-to-DC conversion are designed to keep voltage regulation tight and reduce coil whine.

What comes with the power supply and what must I source separately?

The unit itself is supplied; ATX power cables for motherboard, CPU, GPU and drives are typically included. You will need to provide a mains power cord if one is not already available.

Which capacity should I choose for a build that needs 60A on the 3.3V rail?

This model provides 60A on the 3.3V rail with a total 300W rating, matching the PBA300F-3R3 specification. Select it when your system’s 3.3V demand and overall power draw fit within those limits.
