Replacement 300 W ATX Unit

This KHACHIMO power supply replaces the original FSP 610 300 W unit in compatible systems. It matches the ATX form factor and 300 W output so the swap is electrically equivalent. The 80 PLUS Gold certification delivers higher efficiency than many older OEM units. Modern Standby support enables faster wake times than legacy designs.

Upgrade From Lower Efficiency PSUs

The jump is worthwhile when replacing an 80 PLUS Bronze or unrated 250 W to 300 W supply that runs hot or noisy. Gold-rated efficiency cuts waste heat and lowers fan speed at typical loads. Zero RPM mode eliminates fan noise entirely during light workloads. Resonant LLC topology with DC-to-DC conversion reduces coil whine compared to older group-regulated designs.

Straightforward ATX Installation

Installation follows standard ATX mounting and connector routing; no proprietary brackets are required. Ensure the main 24-pin and CPU power cables reach the motherboard headers in your chassis. The most common issue is cable length in larger cases or non-standard motherboard layouts. Verify connector compatibility with the target board before fitting.

Questions about this item

Will the ATX form factor fit the same mounting holes as the FSP 610 chassis?

Yes, the ATX form factor uses the standard mounting pattern that matches the FSP 610 chassis screw locations.

Does the 24-pin ATX connector plug straight in, or do I need to repin for the FSP 610 motherboard?

The 24-pin ATX connector plugs directly into the FSP 610 motherboard without repinning; the only step often missed is fully seating the latch until it clicks.

When should I expect to replace the cooling fan on this 300W unit?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, so the fan typically lasts several years longer than constantly spinning units; replace it if bearing noise appears.
