What a 9800X3D Build Actually Asks of the Board

The Ryzen 7 9800X3D is an eight-core Zen 5 part with 96MB of L3, most of it on a cache die stacked underneath the cores rather than on top of them. Its rated 120W and package ceiling near 162W are modest next to a sixteen-core processor, so power delivery is rarely what separates one board from another here. Firmware revision, memory slot layout and how the board shares its PCIe lanes matter far more.

Every AM5 chipset from the entry tier upward will run this processor once the firmware knows about it. What the tiers change is USB4, whether PCIe 5.0 reaches the graphics slot, how much tuning the board will allow, and how many drives fit before something drops to half width. Evetech stocks AM5 boards at Limeroc Business Park in Centurion.
