ATX motherboard and CPU combo with AM5 socket, X870E chipset, 110A SPS VRM, 64MB BIOS, DDR5 up to 9000 MT/s, five M.2 slots, 10G and 5G LAN.
CPU +Ryzen 7 9800X3D
This motherboard and CPU bundle pairs the MSI MEG X870E ACE MAX with the AMD Ryzen 7 9800X3D processor. The board uses the X870E chipset on an ATX form factor and supports AM5 socket processors from the 7000, 8000 and 9000 series. The CPU delivers 8 cores and 16 threads based on the Zen 5 architecture with a 5.2 GHz max boost clock and 96 MB L3 cache. It targets enthusiasts who want a matched platform for gaming and heavy workloads.
The combo arrives with the CPU and motherboard in one package, so socket alignment is the only critical step. Apply thermal paste, seat the cooler, and connect the 8-pin and 24-pin power cables before populating the four DDR5 slots up to 256 GB total. The 64 MB BIOS ROM simplifies memory training and future CPU updates. Common issues include forgetting the CPU power cable or not fully seating memory modules, which the debug LEDs help identify quickly.
The 18+2+1 DRPS power design rated at 110 A SPS feeds the CPU cleanly during long rendering or compile sessions. The Frozr heatsink array with direct-touch heat pipes, aluminium covers and double-sided M.2 shields keeps VRM and SSD temperatures in check without fan noise spikes. Dual 10 GbE and 5 GbE LAN controllers maintain throughput during large file transfers, while the Realtek ALC4082 audio codec stays clean under electrical load.
