450W ATX power supply for efficient builds

This KHACHIMO ACE450F unit delivers 450W of continuous power in a standard ATX form factor. It is suited for mainstream desktop systems that prioritise energy efficiency and low acoustic output. The 80 PLUS Gold certification confirms high efficiency across typical load ranges.

Modern Standby and zero-fan operation change daily

Modern Standby compatibility enables extremely fast wake-from-sleep times and improves low-load efficiency. The Zero RPM fan mode stops the cooling fan completely at low and medium loads, removing audible noise during light work. Resonant LLC topology with DC-to-DC conversion supplies clean power and reduces coil whine.

ATX layout and quiet cooling simplify integration

The ATX footprint fits standard chassis mounting points without adapters. Resonant LLC design and DC-to-DC conversion lower internal temperatures, which helps the fan stay off longer. Gold-rated efficiency cuts waste heat, so case airflow demands stay modest even during sustained loads.

Questions about this item

How often will the cooling fan need replacement on the ACE450F?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, reducing wear so the fan typically lasts the life of the unit without replacement.

What limits sustained output on the ACE450F?

The 450 W rated capacity is the ceiling; continuous draw above that triggers protection and the unit will shut down.

How much heat and noise does the ACE450F produce when running all day?

80 PLUS Gold efficiency and Zero RPM Fan Mode keep heat low and the fan silent at typical loads; only heavy sustained loads spin the fan audibly.
