ASUS TUF GAMING B850M-E WIFI & Ryzen 7 9850X3D AMD motherboard combo

SKU CH-56HB-SCA2K

Combines an AM5 micro-ATX board with 10 Gbps USB-C, WiFi 6E and 2.5 Gb Ethernet with an 8-core, 16-thread Ryzen 7 9850X3D CPU featuring 96 MB L3 cache and 5.6 GHz boost

  • CPU Socket TypeAM5
  • 8 cores and 16 threads on Zen 5 architecture for high frame rates
  • 96 MB L3 cache with second-gen 3D V-Cache cuts gaming latency
  • 80 A DrMOS power stages and 8-layer PCB keep VRMs cool
  • WiFi 6E and 2.5 Gb Ethernet give lag-free online play
  • Four DDR5 slots with AEMP 3.0 simplify memory tuning

Combo for AM5 gaming builds

This bundle pairs an ASUS TUF GAMING B850M-E WIFI motherboard with an AMD Ryzen 7 9850X3D processor. The board uses the AM5 socket and supports Ryzen 9000, 8000 and 7000 series CPUs. It targets gamers who want a ready-to-run platform with WiFi 6E and 2.5Gb Ethernet.

Sustained-load power and thermal design

The motherboard employs 8+2+1 DrMOS power stages rated at 80A each on an 8-layer PCB with AI Overclocking. Enhanced VRM and M.2 heatsinks cover the PCIe 5.0 x4 slot to maintain temperatures during extended sessions. Four dual-channel DDR5 slots use AEMP 3.0 for stable memory operation.

96MB L3 cache with 3D V-Cache technology

The Ryzen 7 9850X3D delivers 8 cores and 16 threads on Zen 5 architecture with a 5.6 GHz max boost clock. Its 2nd-gen 3D V-Cache provides 96MB L3 cache plus 8MB L2 cache to reduce gaming latency. DDR5-5600 support and PCIe 5.0 capability complete the specification.

Questions about this item

How loud or hot does the 80A DrMOS power stage get when the Ryzen 7 9850X3D runs all day at 5.6 GHz?

The 8(80A)+2(80A)+1(80A) DrMOS design and 8-layer PCB spread heat across enhanced VRM and M.2 heatsinks, keeping temperatures controlled during sustained loads.

Which DDR5 memory kit do I need to add so the four DIMM slots work with AEMP 3.0?

Install a DDR5-5600 dual-channel kit; the four slots and ASUS Enhanced Memory Profile 3.0 will configure timings automatically.

Will my PCIe 5.0 x16 graphics card fit the SafeSlot and run at full speed alongside the 9850X3D?

Yes, the PCIe 5.0 x16 SafeSlot is wired for Gen 5 bandwidth and the CPU provides 16 lanes, so current high-end GPUs operate without bottleneck.
