Product identity
The Qnap TS-432PXU-RP-2G-US is a 1U rackmount NAS with four SATA drive bays and an AnnapurnaLabs Alpine AL324 quad-core ARM Cortex-A57 processor running at 1.7 GHz. It ships with 2 GB of memory and dual redundant 250 W power supplies. The unit targets small-business or departmental environments that need multi-user file services in a compact rack footprint.
Capacity and headroom
Four bays accept 3.5-inch or 2.5-inch SATA hard drives and SSDs up to a raw maximum of 88 TB. Two 2.5 GbE RJ-45 ports and two 10 GbE SFP+ ports provide high-throughput network access for concurrent users. A single memory slot allows expansion to 16 GB DDR4 for heavier workloads. The system operates between 0 and 40 °C with typical power draw of 53.343 W.
Deciding specification
The PCIe Gen2 x2 slot is the single feature that determines whether this chassis fits a given deployment. It enables the addition of a 10 GbE NIC, an M.2 SSD adapter or other expansion cards, turning the base platform into a tailored application server. Without that slot the unit remains a fixed-configuration file appliance.

Questions about this item
Will the 2.5 GbE ports work with my existing gigabit switch?
The two 2.5 GbE RJ-45 ports auto-negotiate down to 1 GbE, so they connect to any standard gigabit switch without configuration.
How do I confirm the redundant power supplies are active after installation?
The front Status LED and the dual PSU indicators on the rear show green when both 250 W units are supplying power; a single amber PSU LED signals a fault.
Does the box include drives or SFP+ modules for the 10 GbE ports?
The unit ships diskless and without SFP+ transceivers; you must purchase four SATA drives (3.5-inch or 2.5-inch) and any 10 GbE SFP+ modules separately.
