KHACHIMO ATX 300W power supply

The KHACHIMO PSR300-A is an ATX form-factor power supply rated at 300 watts. It is built for standard desktop chassis and carries a new condition. The unit has been tested working and is presented as a good-quality replacement part. First listed by the manufacturer in March 2024.

Suits basic desktop builds.

This supply fits office PCs, home-office workstations or entry-level configurations that draw modest power. It is not for gaming rigs, workstations with discrete graphics cards or any build whose components exceed the 300-watt rating. Builders needing headroom for future upgrades should look at higher-capacity units.

300-watt ATX output decides fit

The single specification that determines compatibility is the 300-watt ATX output. If the total system draw stays within this limit and the case accepts a standard ATX supply, the PSR300-A will power the machine. If the build requires more wattage, this unit cannot meet the need.

Questions about this item

Will this PSR300-A unit power on without a 24-pin ATX motherboard connector already installed?

The PSR300-A is an ATX-type supply so it requires a standard 24-pin motherboard connector to deliver power to the system.

Can the PSR300-A run in a chassis that still uses the older 20-pin main power header?

The PSR300-A follows the ATX form factor which normally provides a 24-pin connector; a 20-pin motherboard would need an adapter not mentioned in the specifications.

How can I confirm the PSR300-A is delivering stable voltage after installation?

The supplier notes each unit is test working, so verifying operation means checking that the system posts and runs without unexpected shutdowns.
