Refurbished 12-core AM5 desktop processor

This refurbished AMD Ryzen 9 7900 delivers 12 cores and 24 threads at a 65 W TDP, boosting up to 5.4 GHz on the Zen 4 architecture with integrated Radeon graphics for display output without a discrete card.

Suits AM5 platform builds with DDR5 memory

The processor fits Socket AM5 motherboards using A620, B650, B650E, B850, X670, X670E, X870 or X870E chipsets and supports dual-channel DDR5 5200 up to 128 GB; it is not compatible with older AM4 platforms.

65 W thermal design power

A 65 W TDP means the cooler must handle that heat load; the box includes a Wraith Prism cooler, so builders who plan a different cooling solution should verify it meets or exceeds this rating.

Questions about this item

Does the box include a cooler or do I need to buy one separately?

The 100-100000590BOX package includes a Wraith Prism cooler so no separate purchase is required

Should I choose a B650 or X670 chipset for this 12-core 65W processor?

Both B650 and X670 are listed as compatible; X670 offers more PCIe 5.0 lanes while B650 covers the essentials for the 7900

What does the 5.4 GHz max turbo mean once the chip is installed in a real system?

The 5.4 GHz figure is the peak single-core boost reachable under light loads when power and thermal headroom allow
