450W ATX power supply

The KHACHIMO ACE450F is a 450W ATX power supply designed for desktop builds that need efficient, quiet power delivery. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep performance. Builders who require higher wattage for multi-GPU configurations should look elsewhere.

Practical limits of the ATX standard

ATX power supplies share fixed physical dimensions and connector layouts, so this unit fits standard cases and motherboards without modification. The 80 PLUS Gold rating guarantees at least 80 percent efficiency at typical loads, reducing waste heat and electricity cost. Seasonal temperature extremes or unusual case airflow may still affect thermal margins.

Resonant LLC topology with DC-to-DC conversion

This topology supplies clean, consistent voltage across all rails while suppressing coil whine for quieter operation. It also enables deeper, more energy-efficient sleep states supported by Modern Standby. Systems that demand server-grade redundancy or hot-swap capability are not addressed by this design.

Questions about this item

How do I pick the right capacity for my build?

The 450W rating suits mainstream CPUs and mid-range graphics cards; match the total system draw to this figure.

What does the 80 PLUS Gold label tell me about daily use?

It means the unit runs at high efficiency across typical loads, so less power is wasted as heat and the fan stays off longer.

What does ATX mean for fitting this into my case?

ATX is the standard desktop form factor, so it mounts in any case designed for full-size power supplies.
