450 W ATX Power Supply

The KHACHIMO T440 R540 is a new 450 W ATX switching power supply built for desktop PCs that require efficient, reliable power delivery. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion for clean, stable output. Modern Standby compatibility allows extremely fast wake-from-sleep transitions. A zero-RPM fan mode stops the fan at low and medium loads for near-silent operation.

Quiet, Efficient Desktop Builds

This unit suits builders who prioritise low noise and high efficiency in standard desktop configurations. The zero-RPM mode and Gold-rated efficiency keep acoustics and heat low during everyday workloads. Systems that demand more than 450 W of continuous power or require specialised server-grade features should look at higher-capacity or redundant designs instead.

450 W Capacity

The single specification that decides fit is the 450 W rated output. Verify that the complete system — CPU, GPU, drives and peripherals — stays within this limit under full load. If the planned hardware exceeds 450 W, a higher-wattage supply is required.

Spurningar um þessa vöru

How can I confirm the 450W unit is running correctly after installation?

The 80 PLUS Gold rating shows it meets high efficiency standards, and the Zero RPM fan mode lets you hear the fan stop at low loads, confirming the thermal circuit is active.

What comes with the KHACHIMO T440 R540 and what must I source separately?

The box contains the ATX power supply itself; all mounting screws, modular cables and any adapters for proprietary motherboard connectors need to be purchased separately.

Which capacity should I pick between the 440 and 540 designations?

The model delivers 450 W continuous output; the 440 and 540 labels refer to series codes, not wattage steps, so choose this unit when your build requires a 450 W Gold-rated supply.
