450W 80 PLUS Gold ATX unit

The KHACHIMO ENP450AGT is a new ATX power supply rated at 450W with 80 PLUS Gold certification. It targets builders who want efficient, quiet power delivery for mainstream desktop systems. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine.

Build integration and space

This ATX form-factor unit fits standard chassis layouts and leaves cable routing room for typical component arrangements. Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. The topology supports more energy-efficient sleep states, freeing the system to enter deeper power-saving modes without instability. Active PFC helps maintain stable input current across varying mains conditions.

Suited for quiet mainstream builds

Ideal for users who prioritise low noise and high efficiency in a 450W power envelope, especially with Modern Standby-capable platforms. Builders needing higher wattage for multi-GPU configurations or extreme overclocking headroom should look at higher-capacity units. Systems requiring specialised server-grade redundancy or non-ATX form factors will need different solutions.

Questions about this item

At what sustained load does the 450 W output become the limiting factor?

The unit is rated for 450 W continuous output; sustained draw above that level will trigger protection.

How much noise and heat should I expect when the supply runs all day?

Zero RPM Fan Mode stops the fan at low and medium loads for near-silent operation, and 80 PLUS Gold efficiency reduces waste heat.

Which motherboard power connectors must my build already provide for this PSU to work?

Standard ATX 24-pin main and 4/8-pin CPU connectors are required; the PSU follows the ATX form factor.
