Chassis and Power Configuration

The Athena Power RM-3U300PRR55U2 is a 3U rackmount server chassis with a 550W redundant power supply. It supports ATX, MicroATX and Mini-ITX motherboards. The unit includes a brushed aluminium front bezel and 1.2mm SECC body.

Ideal Users and Limitations

This chassis suits builders who need hot-swap power redundancy in a 3U form factor. It also works for installations that require three 5.25in external bays. Buyers who need more than two internal 3.5in bays should look at larger enclosures. Systems requiring horizontal expansion slots cannot use the vertical-only layout.

Deciding Specification

The 550W redundant power supply is the single specification that determines suitability. It delivers fail-over protection for critical workloads while fitting the 2U power supply cavity. Verify that your total system draw stays within this limit before purchasing.

商品問答

Will a standard ATX board measuring 12 inches by 9.6 inches fit in the 3U chassis?

Yes, the chassis supports ATX (12 in. x 9.6 in.), MicroATX (9.6 in. x 9.6 in.) and Mini-ITX (6.7 in. x 6.7 in.) motherboards.

How do I install the 2U 550W redundant power supply and what step is often missed?

Slide the PSU module in from the rear until it locks, then seat each power module firmly; the common mistake is leaving a module partially inserted so redundancy is not active.

When should I clean or replace the removable air filter on the front bezel?

Inspect the washable filter monthly in dusty environments; rinse and dry it before refitting, and replace it if the mesh is torn or no longer seals against the bezel.
