AsRock 1U2S-B650 1U Rackmount Compact Server Barebone

Overview

The AsRock 1U2S-B650 is a 1U rackmount server barebone built around a single AMD AM5 socket, aimed at integrators who need to build out a compact recording or application server without committing to a pre-configured system. As a barebone, it ships as the chassis, motherboard platform, and drive bays — you supply the AM5 processor, memory, and storage to match the workload, whether that's a VMS host, an edge analytics box, or a general-purpose rack server sitting alongside your switching and storage gear. At 22.24 x 24.62 x 8.07 inches and 25.29 lb, the 1U2S-B650 is a full-depth chassis — plan rack space accordingly, and check cabinet depth before ordering since this is not a short-depth unit that fits a shallow wall rack.

Key Features

• AM5 single-socket platform: lets you pair current-generation AMD desktop-class silicon with server packaging, which is useful when you want more single-thread performance per rack unit than a typical server-socket platform delivers for VMS or analytics workloads.
• 1U rack form factor: the 1U2S-B650 occupies a single rack unit, so a standard 42U cabinet can hold dozens of units — density matters when you're stacking recording servers next to switches and patch panels.
• 25.29 lb chassis weight: light enough for a single tech to rack and cable without a lift, which speeds up install day on multi-unit deployments.
• 22.24 x 24.62 x 8.07 in footprint: confirm this depth against your cabinet before ordering — at over 24 inches deep, it needs a full-depth rack, not a compact network cabinet.
• Taiwan country of origin: manufactured in Taiwan, relevant for buyers tracking country-of-origin requirements on procurement paperwork.

Integration & Compatibility

Because the 1U2S-B650 is a barebone, final compatibility depends on the AM5 processor, memory, and drives you install — confirm CPU and RAM support against AsRock's published qualified vendor list before ordering components. This platform pairs naturally with a rack-mounted network video recorder or VMS build-out, and integrators speccing a multi-camera site often run it alongside PoE network switches in the same cabinet. If you're planning capacity around the 1U2S-B650, a storage and retention planning guide is worth reviewing before finalizing drive selection, since bay count and drive type drive real-world retention.

Frequently Asked Questions

Q: Does the AsRock 1U2S-B650 include a processor?

A: No — it is a barebone chassis. You supply an AM5-compatible AMD processor, memory, and storage.

Q: How deep is the 1U2S-B650, and will it fit my rack?

A: It measures 22.24 x 24.62 x 8.07 inches, so confirm your cabinet supports a full-depth 1U server before ordering.

Q: How much does the 1U2S-B650 weigh?

A: The bare chassis weighs 25.29 lb before CPU, memory, and drives are installed.

Q: Where is the 1U2S-B650 manufactured?

A: Taiwan is listed as the country of origin.

James Everett

I spec a fair number of barebones for VMS builds, and the 1U2S-B650 stands out for putting an AM5 socket into a 1U chassis rather than forcing you onto a server-socket platform you don't need for a mid-size recording workload.

Technical Highlights:

• AM5 single-socket support: gives you access to current AMD desktop-class CPU options in a 1U rack package, which is a different performance-per-watt tradeoff than typical server-socket boards.
• 1U form factor: at 22.24 x 24.62 x 8.07 in, it holds a standard rack unit's height while running full depth — plan cabinet clearance around the 24.62 in dimension specifically.
• 25.29 lb bare weight: manageable for one person to rack, which matters when you're deploying several of these in a single install window.

Deployment Considerations:

• Since this is a barebone, budget separately for an AM5 CPU, memory, and drives — the chassis price is only the starting point of the build.
• Double-check rack depth before ordering — at over 24 inches, the 1U2S-B650 won't fit shallow or wall-mount network cabinets built for switch-only gear.

This is a solid fit for an integrator building a custom VMS or edge-compute server for a mid-size site who wants control over CPU and drive selection rather than a fixed-spec appliance.
