Power for standard ATX builds

The KHACHIMO MRW-3450V-R is a 450W ATX power supply built for everyday desktop systems. Its 80 PLUS Gold certification ensures high efficiency, reducing waste heat and electricity draw. Modern Standby compatibility allows extremely fast wake-from-sleep transitions for supported motherboards. It suits general office work, home media playback and entry-level gaming rigs.

Simple ATX installation with quiet operation

Mounting follows the standard ATX form factor using four screws in any compatible chassis. A 24-pin main connector, CPU power lead and peripheral cables reach typical motherboard layouts without strain. Zero RPM mode keeps the fan off at low and medium loads for silent running, while LLC resonant topology with DC-to-DC conversion minimises coil whine. Ensure all modular or fixed cables seat fully to avoid intermittent power delivery.

Verify connectors and clearance before ordering

Confirm your motherboard requires a standard 24-pin ATX and the correct CPU power configuration (4-pin or 8-pin). Check that the unit's physical length fits your case's power supply bay and that cable routing paths allow airflow. Systems demanding more than 450W continuous draw or multiple high-end graphics cards need a higher-capacity unit.
