Compact 1U ATX power supply

The KHACHIMO FSP300-601U is a 300W ATX unit built for 1U chassis and space-constrained builds. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean power while reducing coil whine.

Upgrade from basic OEM or Bronze units

Replacing a lower-efficiency supply cuts waste heat and fan noise, especially in always-on or sleep-heavy workloads. The jump is worth it when the system spends long periods at idle or in Modern Standby and you want the fan to stay off entirely under light loads. Gold-level efficiency also lowers running costs over the unit's life.

Suits slim workstations and silent-focused builds

Ideal for compact desktops, embedded appliances or quiet home offices where a 1U form factor and near-silent operation matter. Builders needing more than 300W for discrete graphics or high-core-count CPUs should look at higher-capacity units. Systems requiring legacy -5V rails or non-ATX pinouts are not supported by this model.

Questions about this item

Will the 1U height fit my slim chassis?

The unit is a 1U form factor, so it fits standard 1U rack or slim-tower cases that accept an ATX power supply of that height.

How do I connect the 2Pin and P6 cables during installation, and what is the common mistake?

Plug the 2Pin and P6 connectors firmly into their matching motherboard headers; the frequent error is leaving the 2Pin loose, which prevents the board from receiving the -5 V rail.

When should I expect to replace the cooling fan?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, reducing wear, so replacement is typically only needed after many years of continuous high-load use.
