2U 8-bay rackmount NAS
The TS-832PXU-4G-US is a 2U rackmount network-attached storage server with eight SATA drive bays. It targets small and medium businesses that need high-bandwidth file sharing and backup in a compact rack form factor. The AnnapurnaLabs AL324 quad-core ARM Cortex-A57 processor at 1.7GHz drives storage services for multi-user workloads.
Thermals noise and power draw
Typical operating power consumption is 56.412 W from a 250 W single power supply rated for 100 to 240 V input. The unit is rated for continuous operation between 0 and 40 °C with 5 to 95 percent relative humidity non-condensing. No acoustic or fan-speed figures are provided in the specifications.
DDR4 memory expansion constraint
The system ships with 4 GB of DDR4 UDIMM memory installed in a single DIMM slot and supports a maximum of 16 GB. Buyers who need more than 16 GB of system memory cannot meet that requirement with this chassis.

Questions about this item
How do I install the memory upgrade in the single DDR4 DIMM slot?
Power off the unit, open the chassis, locate the one DDR4 DIMM slot on the motherboard, insert a compatible DDR4 module until it clicks, then close the chassis and power on; the system will recognise up to 16GB total.
When will the 250W power supply likely need replacement under continuous operation?
The 250W PSU is rated for 100-240V input and 56.412W typical draw; under 24/7 load in a 0-40°C environment it typically lasts several years before electrolytic capacitor ageing requires a swap.
At what drive count does the single PCIe Gen2 x2 lane become the throughput bottleneck?
With eight SATA bays sharing one PCIe Gen2 x2 connection, sustained sequential transfers across more than four drives will saturate the lane before the individual SATA 6Gb/s links do.
