Product Description

This AMD Ryzen 9 5900X desktop processor is in excellent condition and has been fully tested and verified to ensure stable performance and reliable operation.

Built on AMD's proven 7nm "Zen 3" architecture, this powerful 12-core, 24-thread processor delivers exceptional performance for high-framerate gaming, 3D rendering, video editing, and heavy multi-tasking workloads. Featuring a total cache of 70MB (64MB L3 + 6MB L2) and boost clock speeds reaching up to 4.8GHz, it remains one of the strongest upgrade paths for the AM4 platform.

Designed for Socket AM4 motherboards (X570, B550, X470, B450 with BIOS update), it offers native support for DDR4 memory and PCIe 4.0 expansion speeds.

The processor pins and contacts have been thoroughly inspected, stress-tested, and validated for complete stability. It will be packaged safely in an anti-static tray or protective casing for secure transport.

Note on Cooling & Graphics:

  • The Ryzen 9 5900X has a 105W TDP (Thermal Design Power) and does not include a stock box cooler. We recommend pairing this CPU with a solid dual-tower air cooler (such as the Thermalright Peerless Assassin) or a 240mm/360mm AIO liquid cooler.

  • This processor does not have integrated graphics. A dedicated discrete graphics card (GPU) is required for video display output.
