  • Clean power delivery through resonant LLC with DC-to-DC conversion
  • 56 W output at 28 V 2 A for PD-482805 systems

DC Input Range and Target System

This ATX power supply accepts a 36V-60V DC input and delivers 28V at 2A for a 56W output. It is built specifically for the PD-482805 platform, making it a direct-fit replacement for that hardware.

Efficiency and Acoustic Behaviour

80 PLUS Gold certification means the unit runs with high efficiency, reducing waste heat and overall power draw. A Zero RPM fan mode stops the cooling fan completely at low and medium loads, while the resonant LLC topology with DC-to-DC conversion suppresses coil whine and supports deeper sleep states.

Modern Standby and Build Implications

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency. The ATX form factor fits standard chassis cut-outs, and the DC-input design suits rack or industrial deployments where AC mains are not used.

Highlights

Questions about this item

Will the fan on this KHACHIMO ATX supply need cleaning or replacement after long-term use?

The unit uses a Zero RPM Fan Mode that stops the fan completely at low and medium loads, reducing mechanical wear and the need for frequent cleaning.

What limits sustained output on the 28 V rail of this 56 W unit?

The 28 V rail is rated for 2 A, giving a maximum of 56 W; sustained loads at that level will hit the power ceiling before thermal limits become a concern.

How much noise and heat does this 80 PLUS Gold supply produce when running all day?

At low and medium loads the fan stays off for near-silent operation, and Gold-rated efficiency keeps waste heat low even during continuous use.
