## Long description

Rack 1U server chassis ASRock 1U4LW-B650/2L2T RPSU supports a single AMD Socket AM5 processor (processor not included) and is built around the AMD B650 chipset. The chassis provides four DDR5 UDIMM slots (up to 32 GB, 5200 MHz), four hot-swap 3.5" drive bays, one PCIe x16 Gen4 slot, integrated IPMI, four Ethernet LAN ports and a UEFI AMI BIOS. The unit includes a 450 W main power supply and supports one redundant power supply; it is designed as a 1U rack form factor with a hot-swap fan module for compact server and storage-dense deployments.
Advantages
The chassis combines a compact 1U rack design with four hot-swap 3.5" bays to enable dense storage in limited rack space. Support for DDR5 UDIMM memory and a PCIe Gen4 x16 slot allows modern CPU and expansion card compatibility. Integrated IPMI and multiple LAN ports provide remote management and network connectivity. Redundant power supply support and hot-swap fan module increase serviceability and uptime in rack environments.
Suitable for
Compact rack server installations
Storage-dense applications requiring multiple 3.5" drives
Remote-managed systems using IPMI
Small-scale virtualization or network services

How to use
Install the chassis into a standard 19" rack and mount a compatible Socket AM5 AMD processor on a supported motherboard (processor not included). Populate up to four DDR5 UDIMM modules across the four DIMM slots following the motherboard memory population guidelines, and insert storage drives into the hot-swap 3.5" bays. Connect power using the included 450 W PSU and optionally install a redundant PSU for failover. Configure BIOS (UEFI AMI) settings and use the integrated IPMI interface for remote management and networking setup via the available LAN ports.
Usage recommendations
For reliable operation, use server-class DDR5 UDIMM modules within the supported voltage and capacity limits, ensure adequate rack airflow for the 1U chassis, and install a redundant power supply when high availability is required. Dispose of the product according to local electronic waste regulations.
