300W ATX Power Supply

The KHACHIMO P1S-6300V delivers 300 watts of continuous power in a standard ATX form factor. It targets builders assembling compact office PCs or basic home systems that prioritise efficiency over high-output performance. The unit supports Modern Standby for rapid wake-from-sleep transitions.

80 PLUS Gold & Zero RPM Mode

Gold certification confirms high efficiency across typical loads, reducing electricity draw and heat output. The Zero RPM fan mode stops the cooling fan completely at low and medium loads, eliminating mechanical noise during idle or light office work. Resonant LLC topology with DC-to-DC conversion supplies clean power and minimises coil whine.

300 Watt Capacity Limit

The 300 watt rating restricts this unit to configurations without discrete graphics cards or high-core-count processors. Builders planning dedicated GPUs, multi-drive arrays or overclocked CPUs must select a higher-capacity power supply to avoid instability.

Questions about this item

Does the 300W KHACHIMO P1S-6300V power supply have any user-serviceable parts like a replaceable fan or fuse?

The unit is a sealed ATX power supply with no user-serviceable components inside; if the fan or any internal part fails the entire supply must be replaced.

What protection activates first when the 300W KHACHIMO P1S-6300V runs at full load for hours?

The over-temperature protection will trip before any other limit if the internal temperature rises too high during sustained maximum output.

How loud is the 300W KHACHIMO P1S-6300V when the system idles all day?

At low and medium loads the Zero RPM Fan Mode stops the fan completely, so the power supply produces no audible noise while the PC is idle.
