QNAP TS-473AAMD Ryzen 4-Bay Tower NAS

AMD Ryzen V1500B8GB ECC, up to 64GBDual 2.5GBE2x PCIe Gen3 x4

The QNAP TS-473A (part number TS-473A-8G) is a four-bay tower NAS powered by anAMD Ryzen Embedded V1500B quad-core, eight-thread processor with 8GB of ECC DDR4 memory, built for demanding small-business storage, virtualization and data protection. Two PCIe Gen3 x4 expansion slots let you add 10GBE networking, extra M.2 NVMe SSDs or a graphics card, while dual 2.5GBE, two onboard M.2 slots and support for up to 64GB ECC RAM give it far more headroom than entry-level units. Typically in stock with fast delivery across Cyprus.

Before you buy — sold diskless
This NAS ships without drives. Fit up to four 3.5-inch or 2.5-inch SATA drives plus optional M.2 2280 NVMe SSDs for caching. It has no onboard video ouTPUt — HDMI and hardware transcoding require a compatible PCIe graphics card. QNAP recommends QNAP-branded ECC memory modules for upgrades.

Best For

✓Small-business file servers and virtualization hosts
✓Running multiple VMs and Docker containers
✓Workloads that benefit from ECC memory data integrity
✓Adding 10GBE or 25GBE via PCIe upgrade cards
✓Snapshot-protected backup and disaster recovery
✓Users who plan to scale RAM up to 64GB

Key Features

 
AMD Ryzen server-class CPU
The quad-core, eight-threadAMD Ryzen Embedded V1500B with AES-NI encryption delivers strong multitasking and virtualization performance, comfortably ahead of Celeron-based four-bay NAS units.
 
ECC memory for data integrity
Ships with 8GB of ECC DDR4 and scales to 64GB across two SO-DIMM slots, helping prevent silent data corruption in always-on business storage.
 
Dual PCIe expansion
Two PCIe Gen3 x4 slots accept 10GBE/25GBE NICs, QM2 cards for additional M.2 NVMe SSDs, or a GPU for transcoding and AI — rare flexibility in a four-bay NAS.
 
Flexible storage & OS
Four SATA bays plus two M.2 2280 Gen3 slots for caching, with a choice of QTS (ext4) or QuTS hero (ZFS) operating systems and full iSCSI support.

Frequently Asked Questions

Does the TS-473A come with drives?
No, it is supplied diskless. It accepts four 3.5-inch or 2.5-inch SATA drives plus up to two optional M.2 2280 NVMe SSDs for caching.
Does it have an HDMI port?
No. The TS-473A has no onboard video ouTPUt. If you need HDMI ouTPUt or hardware transcoding, install a compatible graphics card in one of the two PCIe slots.
How much memory can it take, and is it ECC?
It ships with 8GB of ECC DDR4 and supports up to 64GB (2x 32GB) of ECC SO-DIMM memory, ideal for virtualization and data-integrity-sensitive workloads.
What is the difference between the TS-473A and TS-673A or TS-873A?
They share the same Ryzen V1500B platform, RAM, M.2 and PCIe layout; the difference is bay count — four bays on the TS-473A, six on the TS-673A and eight on the TS-873A.
Singular Expert Insight
The TS-473A is the pick when you want server-classAMD Ryzen power, ECC memory and real PCIe expansion in a compact four-bay tower. If you need more spindles, the TS-673A (6-bay) and TS-873A (8-bay) share the same platform. Compared with the Intel Celeron TS-464, the TS-473A offers ECC support, 64GB maximum RAM and dual PCIe x4 slots for far greater growth. Populate it with 24/7-rated NAS hard drives and add a 10GBE card when your network is ready.

Buyer's Guide

Buy it if
You want a Ryzen-powered 4-bay NAS with ECC memory, 64GB RAM headroom and two PCIe slots for 10GBE or extra NVMe.
Skip it if
You rely on built-in HDMI ouTPUt for local media playback — this model has none without a PCIe graphics card.
Also consider
The 6-bay TS-673A or 8-bay TS-873A for more capacity, or the Intel TS-464 if you need onboard HDMI and lower cost.
