High-Capacity Server Power Supply

The ASRock Rack 04G180003001AK is a 1600W CRPS power supply designed for server chassis that accept this redundant form factor. It delivers high-output power for dense compute nodes or storage arrays requiring substantial wattage in a compact footprint.

Suited for Redundant CRPS Bays

This unit fits servers built for CRPS modules with reverse airflow, such as the referenced 2U2E-F and ROME2 platforms. It is not for towers or workstations using standard ATX or EPS supplies, nor for systems lacking the matching CRPS cage and backplane.

Verify Chassis Compatibility First

Confirm your server accepts a CRPS supply measuring 7.68" x 2.89" x 1.54" and weighing 6.61 lbs. Ensure the chassis provides the correct connector pinout and reverse-fan cooling path before ordering.

Questions about this item

What server chassis or backplane is required to accept this CRPS 1600W form factor?

This supply uses the CRPS redundant form factor and fits 2U2E-F and ROME2 chassis that provide matching CRPS bays.

Will the reverse-airflow fan direction cool properly in a standard front-to-back server?

The fan pulls air from the rear and exhausts toward the front, so it is designed for chassis with reverse airflow paths, not standard front-to-back layouts.

How can I verify the unit is delivering power after installation?

Check the chassis management interface or front-panel LEDs for power-good status and confirm the system posts without power-related errors.
