Designed for GPU server workloads

The Athena Power RM-4U8G1043 is a 4U rackmount chassis built to accommodate full-height expansion cards and high-density storage. It supports motherboards up to E-ATX dimensions and includes a four-port mini-SAS backplane rated at 12 Gb/s. Three 120 mm DC fans provide directed airflow for compute-intensive configurations.

Verify motherboard size and power connections

Confirm that your board fits within the supported MicroATX, ATX, E-ATX or Mini-ITX footprints before ordering. The front hot-swap bays require a compatible SAS controller or HBA with mini-SAS connectors. Ensure your rack depth can accept the 21.57 inch chassis length and that the 28.60 lb weight is within your rail rating.

Replaces tower or 2U cases needing more slots

This chassis upgrades from enclosures limited to fewer than eight full-height PCI slots or lacking hot-swap drive access. The jump is worth it when you need simultaneous GPU acceleration and four front-accessible drives in a standard 4U rack footprint. It does not suit builds requiring 5.25 inch optical bays or external 3.5 inch drive trays.

Questions about this item

Does the chassis come with the 4-port 12 Gb/s mini-SAS backplane installed, or must I buy it separately?

The 4-port 12 Gb/s mini-SAS hot-swap backplane is included and factory-fitted; no separate purchase is needed.

Which motherboard form factors fit in the RM-4U8G1043?

The chassis supports Mini-ITX, MicroATX, ATX and E-ATX boards up to 12" x 13".

How many full-height GPU or add-in cards can I install with the eight expansion slots?

All eight slots accept full-height cards, so you can populate every slot with a dual-slot GPU or other add-in board.
