AsRock 1U2N2G-B550 1U Rackmount Multi-Node GPU Server Barebone

Overview

The AsRock 1U2N2G-B550 is a 1U rackmount server barebone built around a multi-node, single-socket architecture designed to pack GPU-accelerated compute density into standard 19-inch rack space. The 1U2N2G-B550 (often searched as 1U2N2G B550) ships as a barebone chassis platform — the mechanical and structural foundation for integrators who need to configure compute nodes to their own CPU, memory, and GPU specification rather than buying a fixed configuration.

Key Features

• 1U Rack Form Factor: Fits standard 19-inch rack rails without consuming 2U or 3U of valuable rack space — a meaningful density advantage in colocation or on-prem server rooms where rack unit cost is a real budget line.
• Multi-Node Design: Two independent single-socket nodes housed in one 1U chassis, letting an integrator run separate workloads or compute clusters from a single rack slot instead of dedicating a full chassis per node.
• Chassis Footprint — 31.89 x 25.20 x 9.45 in (L x W x H): Confirm rack depth before ordering — at nearly 32 inches deep, this exceeds shallow-depth rack enclosures and needs a cabinet with adequate rear clearance for cabling and airflow.
• System Weight — 45.90 lb: Plan for two-person handling during rack installation; factor this into rail-kit weight ratings and rack stability calculations, especially near the top of a populated cabinet.
• Barebone Configuration: Ships without CPU, memory, GPU, or storage populated, giving integrators full control to match compute and thermal budget to the target workload instead of paying for a fixed bill of materials that may not fit the job.

Integration & Compatibility

As a barebone platform, the 1U2N2G-B550 is intended to be built out by an integrator selecting compatible processors, memory, storage, and GPU accelerators for each node. It is manufactured in Taiwan (TW country of origin), a factor worth noting for government and NDAA-scoped procurement where country-of-origin documentation is required during vendor qualification — confirm current compliance status for your specific contract before specifying this platform. This barebone fits alongside standard network video recorders and rack infrastructure in a data center or server room build-out, and pairs naturally with rackmount power supply units and cable management accessories sized to its 1U profile. For guidance on planning rack space, power, and airflow around dense compute platforms like this, see the network and power planning guide. Additional AsRock server barebones and configured systems are available in the broader AsRock catalog, and integrators comparing rack-mount compute options should also review the rackmount server category for higher-node-count or single-node alternatives.

Frequently Asked Questions

Q: Does the 1U2N2G-B550 come with CPU, memory, or GPUs installed?

A: No — this is a barebone chassis platform. It ships without processors, memory, storage, or GPU accelerators populated, so integrators configure each node to their own compute requirements.

Q: How many nodes does the 1U2N2G-B550 support in its 1U chassis?

A: The platform is a multi-node design with two independent single-socket nodes in a single 1U rack enclosure.

Q: How much does the 1U2N2G-B550 weigh, and how deep is the chassis?

A: The barebone chassis weighs 45.90 lb and measures 31.89 x 25.20 x 9.45 in (L x W x H) — confirm your rack cabinet has sufficient depth clearance before ordering.

Q: Where is the 1U2N2G-B550 manufactured?

A: Country of origin is Taiwan (TW).

Jerry Tildsen

The 1U2N2G-B550 crosses my desk most often from integrators trying to squeeze two independent compute nodes into a single rack unit rather than burning 2U on separate single-node chassis. At 45.90 lb and 31.89 x 25.20 x 9.45 in, it's a substantial barebone — the depth in particular is the number I tell people to check twice against their cabinet before ordering.

Technical Highlights:

• 1U, dual single-socket node layout: two independent compute nodes in one rack unit is real density — useful when rack space is the constraint, not power or cooling headroom.
• 45.90 lb chassis weight: heavy enough that I always flag it for two-person lift during install, and it factors into your rail kit's rated load once nodes are populated.
• 31.89 in depth: this is not a shallow-depth chassis — measure your cabinet's usable rear clearance before this ships, especially in edge or wall-mount rack enclosures.

Deployment Considerations:

• This is a barebone — budget separately for CPU, memory, storage, and GPU accelerators per node, and confirm compatible part numbers before ordering the chassis.
• Taiwan country-of-origin documentation may be relevant if this is going into a government or NDAA-scoped procurement; verify current compliance requirements against your specific contract.

Where I'd point this: a colocation or on-prem rack build where a customer needs two GPU-capable compute nodes provisioned close together for a small inference or rendering cluster, and rack unit cost is the binding constraint on the design.
