1U 1000W ATX power module

This 1U form-factor ATX power module delivers 1000 W of continuous power for rack-mount servers and compact workstations. Its 80 PLUS Gold certification ensures high efficiency across the load range, reducing operating cost and waste heat. Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency.

Thermals, noise and power draw

The Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion supplies clean, consistent power while reducing coil whine. High Gold-rated efficiency lowers overall power consumption and keeps internal temperatures cooler during normal use.

Build integration

The 1U height frees vertical space in dense chassis and leaves room for additional expansion cards or storage drives. ATX connector layout fits standard server backplanes without adapters. Modern Standby support allows the platform to enter deeper sleep states, saving energy when the system is idle.

Questions about this item

How do I install the 1U 1000W power supply into a rack chassis and what step is often missed?

Slide the unit into the 1U bay, secure the mounting screws, then connect the 240-pin CPSU-0240 edge connector fully until it clicks; the step often missed is not seating that connector completely, which prevents the PSU from powering on.

What maintenance or replacement will the 1000W power supply need over time?

The internal cooling fan is the only moving part; after years of continuous operation its bearings may wear, so plan to replace the fan assembly when noise increases or the Zero RPM mode stops engaging at low loads.

What limit appears first when the 1000W unit runs at sustained high load?

The 80 PLUS Gold efficiency curve drops above 80 % load, so sustained output near 1000 W generates the most heat and will trigger thermal protection before the electrical limit is reached.
