Compact 1U Server PSU

The KHACHIMO AIO 1U 12V 450W unit is an ATX power supply built for rackmount chassis and space-constrained builds. It delivers 450 watts of continuous power on a single 12 volt rail for modern components.

80 PLUS Gold and Zero RPM

Gold certification means higher efficiency at typical loads, reducing waste heat and electricity draw. The Zero RPM fan mode stops the fan completely at low and medium loads, eliminating audible noise during idle or light work.

LLC Resonant Topology Limits

The resonant LLC design with DC-to-DC conversion improves voltage regulation and enables deeper sleep states such as Modern Standby. Builders needing multiple 12V rails or higher wattage for multi-GPU configurations should look elsewhere.

Questions about this item

Will the 80 PLUS Gold certified 450W unit need its fan replaced after years of continuous use?

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 supply under normal conditions.

What limit appears first when the 12V 450W supply runs at full load for hours?

The 450W total power rating is the hard ceiling; sustained loads above it will trigger over-current protection and shut the unit down.

How much noise and heat does the 1U 12V 450W PSU produce when running all day?

At low and medium loads the fan stops completely for silent operation, while 80 PLUS Gold efficiency keeps waste heat and noise low even at higher loads.
