AsRock 1U4LW-X570 RPSU 1U Single-Socket AM4 Rackmount Server Barebone

The AsRock Rack 1U4LW-X570 RPSU is a 1U rackmount server barebone built around a single AM4 socket with the X570 chipset, configured with 4 drive bays and a redundant power supply for shops that need AMD Ryzen-class compute density in a compact rack footprint. At 31.1 x 25.2 x 9.05 inches and 35.5 lb, it occupies a single rack unit while leaving room for full-size drive carriers and dual PSU modules — the kind of chassis you spec when you want AM4 core counts without moving up to a 2U chassis just for redundancy.

Overview

This is a barebone chassis and motherboard platform, not a complete turnkey server — CPU, memory, drives, and OS are supplied separately by the integrator. The 1U4LW-X570 RPSU (often searched as 1U4LW X570 RPSU) targets deployments where rack space is constrained but power redundancy still matters, such as edge compute nodes, branch-office application servers, or dedicated recording/analytics hosts sitting in a shared rack with switches and patch panels.

Key Features

• 1U form factor: a single rack unit keeps density high in racks already carrying switches, NVRs, or patch panels — fewer U's spent per server means more room for expansion elsewhere in the cabinet.
• Single-socket AM4 platform (X570 chipset): lets you build around AMD Ryzen desktop-class CPUs in a rack chassis, an option worth considering when per-core pricing or platform cost matters more than dual-socket scale.
• 4 drive bays: enough bays for a small RAID array or a mix of OS and storage drives without stepping up to a taller chassis.
• Redundant power supply (RPSU): if one PSU module fails, the second keeps the system running — the difference between a scheduled swap and an unplanned outage on a production box.
• 35.5 lb chassis weight: heavy enough to confirm a steel/mixed-metal 1U build; plan for two-person rack installation or a rail-mounted lift, especially once drives and a PSU pair are loaded.

Integration & Compatibility

Because this ships as a barebone, compatibility depends on the AM4/X570 components you pair with it — confirm CPU, memory, and drive compatibility against AsRock Rack's own documentation before ordering parts. Manufactured in Taiwan, consistent with AsRock Rack's standard production sourcing for this server line.

Frequently Asked Questions

Q: Is the 1U4LW-X570 RPSU a complete server or a barebone kit?

A: It is a barebone chassis and motherboard platform — CPU, RAM, storage, and OS are added separately by the integrator.

Q: How many drive bays does the 1U4LW-X570 RPSU have?

A: Four drive bays.

Q: Does the 1U4LW-X570 RPSU include a redundant power supply?

A: Yes, the RPSU designation indicates a redundant PSU configuration.

Q: What socket and chipset does the 1U4LW-X570 RPSU use?

A: A single AM4 socket with the X570 chipset.

Q: How much does the 1U4LW-X570 RPSU weigh, and will it fit standard rack rails?

A: The chassis weighs 35.5 lb with dimensions of 31.1 x 25.2 x 9.05 inches, sized for a standard 1U rack space.

James Everett

The 1U4LW-X570 RPSU is one of the few 1U platforms I spec when a customer wants AM4 flexibility with power redundancy baked in, rather than jumping to a dual-socket 2U just to get a second PSU.

Technical Highlights:

• Redundant PSU: a failed power module doesn't take the box down — it keeps running on the second supply until you swap the failed unit.
• 4 drive bays: enough for a small mirrored or striped array plus a boot drive without moving to a taller chassis.
• 1U footprint at 31.1 x 25.2 x 9.05 in: fits standard rack depth in most cabinets, but measure your rack's usable depth before ordering — this is a deep 1U chassis.

Deployment Considerations:

• This ships as a barebone — budget separately for an AM4 CPU, memory, and drives, and confirm compatibility against AsRock Rack's own qualified component list before ordering.
• At 35.5 lb before drives and a second PSU are installed, plan for rail-mounted installation rather than a solo lift into the rack.

Good fit for a branch-office or edge compute node where rack space is limited but you still want PSU redundancy on an AMD AM4 platform — not the choice if you need dual-socket scale or a fully assembled turnkey server.
