KHACHIMO 450W ATX Gold PSU

The KHACHIMO ST-450PAP is a new 450W ATX power supply certified to 80 PLUS Gold efficiency. It uses Resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power to system components. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation.

Ideal for efficient mainstream builds

This unit suits builders assembling modern desktops that benefit from high efficiency, quiet running and fast sleep-state transitions. It fits standard ATX cases and supports current low-power sleep states. Systems requiring substantially higher wattage for multi-GPU arrays or extreme overclocking headroom should consider higher-capacity units instead.

450W continuous output rating

The single specification that determines suitability is the 450W rated capacity. Match this figure against the total peak power draw of your chosen CPU, graphics card, drives and peripherals. If the platform demand exceeds this rating, the power supply cannot safely support the build.

Questions about this item

What cables come attached to the KHACHIMO ST-450PAP and do I need to buy any separately?

The power supply has fixed cables including the ATX, CPU and PCIe connectors; no extra cables are required for a typical build.

Should I choose the 450 W model or a higher wattage for a mid-range GPU?

The 450 W rating suits mainstream CPUs and mid-range graphics cards; pick a higher wattage only if your total system draw will exceed this figure.

What does the 80 PLUS Gold rating mean for my daily power bill and noise?

It guarantees at least 80 % efficiency at typical loads, so the unit wastes less electricity, runs cooler and lets the Zero RPM fan stay off longer.
