3U Rackmount Server Chassis

The Athena Power RM-3U300PR80U2 is a 3U rackmount server chassis designed for standard rack installations. It supports MicroATX, ATX and Mini-ITX motherboards and includes a 2U 800W IPC power supply. The brushed aluminium front bezel and 1.2mm SECC construction provide a durable enclosure for server deployments.

Suits Single-Socket Builds Needing Seven

This chassis suits builders who require seven vertical full-height expansion slots and three external 5.25-inch drive bays in a 3U form factor. Two internal 3.5-inch drive bays support local storage. Buyers who need more internal drive bays, additional expansion slots or redundant power supplies should look at alternative chassis designs.

800W Power Supply Determines GPU And Drive Headroom

The included 2U 800W IPC power supply is the specification that decides whether this chassis meets your power budget. It must deliver enough wattage for the motherboard, all installed expansion cards and the two included 80mm front fans plus any optional 60mm fans. Verify total system draw against the 800W rating before committing.

Questions about this item

How do I mount the 2U 800W IPC power supply in this 3U chassis?

The chassis is designed for a 2U 800W IPC power supply; secure it with the supplied screws through the rear mounting flange, ensuring the IEC inlet aligns with the cut-out.

What maintenance does the removable air filter need?

Slide the filter out from the front bezel, wash it with mild detergent and water, let it dry completely, then reinstall it to maintain airflow.

When will the two front 80mm fans become the thermal bottleneck?

Under sustained load the two 80mm front fans move a fixed air volume; if total component TDP exceeds what that airflow can dissipate, internal temperatures will rise first.
