Refurbished ThinkStation P340 Tiny: buyer guide

The ThinkStation P340 Tiny is one of the strangest machines Lenovo has ever built. It measures roughly 179 by 182 by 37 millimetres, weighs around 1.3 kilograms, and inside that one litre chassis Lenovo fitted an ISV certified workstation platform with a genuine Xeon option and a real Nvidia Quadro card. On the refurbished market it is one of the best value professional desktops in the UK.

What the P340 Tiny actually is

Lenovo launched the P340 Tiny in 2020 as a Comet Lake workstation on the Intel W480 chipset. That chipset accepts vPro Xeon parts and ECC memory alongside the familiar Core i5, i7 and i9 chips. The board carries two SO-DIMM slots up to 64 gigabytes total, one M.2 2280 NVMe slot, one M.2 2242 slot for WiFi, and a 2.5 inch SATA bay.

The exterior is the tool free ThinkCentre M90q shell, but the internals are tuned differently. Fans are more aggressive, the power brick is a 170 watt or 230 watt unit rather than the 90 watt consumer version, and the BIOS exposes proper workstation controls including PXE, TPM 2.0 and Computrace. It is ISV certified for SolidWorks, AutoCAD, Revit, Creo, CATIA and several Adobe applications.

The Xeon and Quadro combination

The headline configuration is a Xeon W-1250 or W-1270 paired with an Nvidia Quadro P620 low profile card. The W-1270 gives you eight cores and sixteen threads at 3.4 gigahertz base, 5.0 gigahertz turbo, with ECC support. The P620 is a 40 watt Pascal card with four Mini DisplayPort outputs and 2 gigabytes of GDDR5, modest by gaming standards but perfectly matched to 2D CAD, viewport work, and multi monitor setups.

Not every P340 Tiny ships with the Quadro. Many were sold with Intel UHD 630 graphics only, and those remain capable for office and light creative work. The Quadro version is worth an extra hundred pounds or so, and it is the one to hunt for if you have any CAD, GIS or professional video output requirements.

Spec ranges on the refurbished market

Refurbished P340 Tiny stock in the UK varies widely. Typical configurations cover the following ranges:

• CPU: Intel Core i5 10500, i7 10700, i9 10900, Xeon W-1250, W-1270, W-1290
• Memory: 8 gigabytes up to 64 gigabytes, DDR4 2933 SO-DIMM, ECC or non ECC
• Storage: 256 gigabyte NVMe up to 1 terabyte NVMe, sometimes plus a 2.5 inch SATA drive
• Graphics: Intel UHD 630 integrated, or Nvidia Quadro P620 discrete
• Power supply: 170 watt brick standard, 230 watt where a Quadro is fitted
• Operating system: Windows 10 Pro or Windows 11 Pro

Prices in mid 2026 sit roughly between £220 for a bare i5 machine and £520 for a fully loaded Xeon W-1270 with 32 gigabytes ECC, 1 terabyte NVMe and the P620. Anything above that and you are paying new money for a five year old chassis.

Use cases the P340 Tiny genuinely suits

For architects and small engineering practices running AutoCAD LT, Revit LT, SketchUp or SolidWorks on modest assemblies, the Xeon plus Quadro combination handles daily work without complaint. It will not replace a full tower for large assemblies or GPU rendering, but for drawing, drafting and viewport work it is quiet, cool and certified.

For trading desks, control rooms and dispatch, the four Mini DisplayPort outputs on the P620 drive four independent monitors at 4K 60 hertz, and the chassis vanishes behind a VESA mounted screen.

For lab automation, medical imaging front ends, machine vision hosts and industrial control PCs, the ISV certification, TPM 2.0, vPro management and long parts availability make it an easier sell to procurement than a consumer NUC. For home labs and Proxmox nodes, the low idle draw (around 12 to 18 watts) and the ECC option give it a place in the small server market too.

Where the P340 Tiny is not the right choice

The P340 Tiny is not a gaming PC or a GPU compute machine. The P620 will not run modern titles at any serious frame rate, and there is no room for a full length card. If you need CUDA at scale, look at a P360 Ultra or a full tower. Sustained all core Xeon workloads will throttle in the one litre chassis, and memory is capped at 64 gigabytes, which rules out very large simulation or virtualisation workloads.

What to check before buying a refurbished unit

Ask the seller to confirm the exact CPU model, whether the memory is ECC or non ECC, the NVMe capacity and health percentage, and whether the correct wattage brick is included. A P340 Tiny with a Quadro fitted needs the 230 watt brick, and the 170 watt unit will cause the GPU to power limit. Check for a twelve month warranty, confirm Windows 11 Pro is activated by digital licence tied to the board, and ask whether the BIOS has been reflashed.

FAQ

Can the ThinkStation P340 Tiny run Windows 11?

Yes. Every CPU option meets the Windows 11 requirements, including TPM 2.0, secure boot and the supported CPU list. Most refurbished units ship with Windows 11 Pro preinstalled and activated by digital licence.

How much memory does the P340 Tiny support?

The board has two SO-DIMM slots and officially supports up to 64 gigabytes of DDR4 2933. Xeon configurations accept ECC modules, while i5, i7 and i9 configurations use non ECC. Populate both slots for dual channel bandwidth.

Is the Quadro P620 enough for CAD work?

For 2D CAD, drafting, and modest 3D viewport work in Revit, SolidWorks and AutoCAD the P620 is comfortable. It is not a rendering card and it will struggle with large assemblies or realtime ray tracing, but for daily design office work it is certified and reliable.

Is a refurbished P340 Tiny a safe business purchase?

Yes, provided you buy from a VAT registered UK refurbisher offering a written twelve month warranty and activated Windows 11 Pro. The P340 Tiny is a business class ThinkStation with long parts availability from Lenovo, and reputable refurbs are reset to factory condition with a fresh install.
