ATX PSU for RAS 57.5V systems

This 1000W ATX power supply delivers 57.5V at 10.4A and 12V at .5A, matching the ARFS-1121-57 unit. It is built for workstations or servers that require this specific high-voltage rail alongside a standard 12V output.

Modern Standby and quiet operation

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. The 80 PLUS Gold certification reduces power consumption, noise and temperatures. Zero RPM fan mode stops the fan at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion provides clean power, reduces coil whine and supports efficient sleep states.

Verify 57.5V rail requirement

Confirm your hardware expects a 57.5V 10.4A rail and a 12V .5A rail before ordering. This unit is not for builds that only need standard ATX voltages or higher 12V current. Ensure the physical ATX form factor fits your chassis and that the connector layout matches the target device.

Questions about this item

Will the fan need replacement after years of continuous operation?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, reducing wear and extending its service life.

What limits sustained output on the 57.5 V rail before protection triggers?

The 57.5 V rail is rated for 10.4 A, so prolonged draws above that level will activate over-current protection.

How loud and hot does the unit get when running at full load all day?

80 PLUS Gold efficiency and Resonant LLC topology keep temperatures lower and the fan quieter even under continuous 1000 W operation.
