Atom Rack — External Overview

Atom Rack is the rack-mounted Threadripper workstation, built in a Macase K550DF 4U chassis. 53 × 44 × 25 cm, 28 kg. Installs on rack rails — a two-person operation for install and slide-out.

Rail installation

For rack rail installation and the slide-out procedure, refer to the Macase K550DF manual — Atom Rack uses the standard Macase rails and installs like any other 4U chassis in that range.

Front panel

The front panel is the face of the rack unit — drive bays (if any) and a minimal front I/O. Most connections happen at the rear.

Rear panel

All ports

• 4 × USB 3.2 Gen 2 Type-A
• 2 × USB4 / Thunderbolt Type-C
• 1 × USB-C 20 Gbps
• 2 × 10 GbE LAN

See Accessing IPMI if your Atom Rack build includes a dedicated IPMI management LAN.

Plug your monitor into the GPU

Not the motherboard

Atom Rack has two full-length PCIe GPUs. Plug your monitor into the primary GPU outputs. In production use, most Atom Racks are managed remotely via IPMI and never have a local monitor plugged in at all.

Power

Atom Rack uses a single 2000 W Platinum ATX power supply. One mains cable plugs into the PSU socket on the rear of the chassis.

Rack installations: confirm that your PDU and circuit can support the peak draw — up to ~8.3 A at 240 V, ~18.2 A at 110 V. See Getting started for the full power and electrical guidance.
