This is a used part that has been tested and is functioning. As a pre-owned component it is sold as-is, but it powered on and worked correctly during testing.
The AMD Ryzen 9 5900X is a 12-core, 24-thread Zen 3 processor with up to 4.8 GHz boost — the sweet spot on AM4 for high-refresh gaming plus streaming, video editing and heavy multitasking, and a huge upgrade for existing B450/B550/X570 boards. Pulled from a working system, tested and sold as shown — a straightforward way to upgrade or repair a AMD Socket AM4 PC without paying new-CPU pricing.

Zen 3 delivered a unified 8-core CCX design and a large IPC jump; the 5900X pairs 12 cores with 64 MB of L3 cache, making it one of the strongest AM4 processors for productivity and gaming together. A 105W TDP means you should plan on a capable tower or AIO cooler (none included). No integrated graphics — requires a discrete graphics card (or a separate GPU) to display video. CPU only (no cooler unless shown in the photos). Check your motherboard's CPU support list and BIOS version before installing.
AM4 boards with 500-series chipsets (B550, X570) work out of the box; B450 and X470 boards work after a BIOS update that adds Ryzen 5000 support. It does not fit Intel or AM5 sockets.
No cooler is included unless one appears in the product photos — plan on a compatible CPU cooler and thermal paste.
Yes. It came out of a working PC and is sold used and working. As a pre-owned part it is sold as-is, and GamerTech technicians can answer compatibility questions before you buy.
