Ryzen 5 PRO 965532GB DDR5512GB NVMe750W Platinum PSU
The Lenovo ThinkStation P4 (model 30KN0040GE) is a tower workstation on AMD's AM5 platform, built for engineering, design and technical teams that want a reliable, expandable base system and to choose their own professional graphics card. This configuration combines the 6-core AMD Ryzen 5 PRO 9655 (up to 5.4 GHz) with 32GB of DDR5-5600, a 512GB PCIe 4.0 NVMe SSD with Opal encryption and integrated AMD Radeon graphics, powered by a 750 W 80 PLUS Platinum supply. It ships with Windows 11 Pro, a discrete TPM 2.0, AMD PRO manageability and a 3-year on-site warranty with 1 year of Premier Support.
Compatibility Note: This is a German configuration: Windows 11 Pro is preinstalled in German (display language can be changed) and the included USB keyboard has a German (QWERTZ) layout. There is no discrete graphics card — outputs use the integrated Radeon graphics (HDMI 2.1, DP 2.0, DP 1.4); add an ISV-certified GPU for 3D CAD or rendering. No Wi-Fi/Bluetooth and no card reader.

Frequently Asked Questions
Can I add a professional graphics card to the ThinkStation P4?
Yes. The tower has PCIe expansion and a 750 W Platinum power supply intended for professional GPUs; check Lenovo's supported-options list for the card and power-cable configuration before ordering.
Is the 30KN0040GE suitable for 3D CAD?
For 2D CAD, BIM viewing and light 3D the integrated Radeon graphics are adequate. For SolidWorks, Revit, 3ds Max or rendering, add an ISV-certified professional GPU; Lenovo publishes ISV certifications for ThinkStation.
Can I change the German keyboard and Windows language?
Windows 11 Pro can be switched to English or Greek through language settings. The keyboard is a physical German QWERTZ layout, so most users in Cyprus replace it with a US/UK or Greek keyboard.
What do I need to know before buying the 30KN0040GE?
It is a German-market configuration without a discrete GPU, Wi-Fi or card reader, with one 32GB DIMM (add a second module for dual-channel bandwidth). It includes 3 years of on-site service.
Singular Expert Insight
The P4 AMD configuration is a sensible base workstation: a modern AM5 Ryzen PRO platform, 32GB DDR5, dTPM and a 750 W Platinum PSU for less than a fully equipped model, so you can add the right professional GPU for your software later. For 3D-heavy users, a configuration with a factory-fitted RTX PRO card may work out simpler; for office CAD the integrated graphics and three video outputs are enough. Pair it with a 4K screen such as the ThinkVision P32UD-40.
✓ Buy it if you want an expandable AM5 workstation base and plan to choose your own professional GPU.
✕ Skip it if you need a GPU out of the box, Wi-Fi, or a local-language keyboard without swapping it.
→ Also consider a ThinkStation P4 configuration with an RTX PRO graphics card for 3D CAD and rendering.
