Combo ready for AM5 builds

The bundle pairs an ASUS PRIME B850-PLUS WIFI motherboard with an AMD Ryzen 7 9700X processor. The board uses the AMD B850 chipset and AM5 socket to support Ryzen 9000, 8000 and 7000 series CPUs. It is aimed at enthusiasts who want a single validated kit for a new DDR5 system.

Suited to gamers and creators; not for compact ITX

The Ryzen 7 9700X delivers 8 cores and 16 threads with a max boost clock of 5.5 GHz and 40 MB cache for high frame rates in games and responsive multitasking. Builders needing a smaller form factor or a different chipset should consider other options.

DDR5-5600 memory support decides compatibility

The processor supports DDR5-5600 speeds while the motherboard adds AEMP optimisation for non-EXPO kits and extensive manual tuning in UEFI. Matching this memory specification is the key factor when selecting RAM for the combo.

Questions about this item

Does the combo include RAM or a cooler, or do I need to buy them separately?

The bundle supplies the PRIME B850-PLUS WIFI motherboard and the Ryzen 7 9700X processor only; DDR5 memory and a CPU cooler must be purchased separately.

Should I choose a DDR5-5600 kit or a faster EXPO module for this board?

The board's AEMP feature optimises standard DDR5-5600 kits automatically, while EXPO modules can run at higher speeds through manual UEFI tuning.

What does the 5.5 GHz boost clock mean for everyday gaming frame rates?

The 8-core, 16-thread Zen 5 chip can hit 5.5 GHz max boost, helping deliver 100+ FPS in popular titles when paired with a capable graphics card.
