Number of RAM slotsKey features of the Asus Pro WS B850M-ACE SE motherboard
- AMD B850 chipset, AM5 socket and mATX format
- Four DDR5 memory slots with speeds up to 8000MHz (OC)
- Main PCIe 5.0 x16 slot and a special MCIO connector
- Two PCIe 5.0 M.2 slots and four SATA III ports
- Networking includes 10Gb, 2.5Gb and a dedicated 1Gb LAN for IPMI
- 8+2+1 power stage design with 80A stages
- Integrated BMC chip for remote management via IPMI
Server-level remote management
The integration of the AST2600 BMC chip delivers complete management via the IPMI interface, which is a standard in server environments. Administrators can remotely monitor system status, perform firmware updates, or restart the system, even if the main operating system is unresponsive. Management of the Asus Pro WS B850M-ACE SE motherboard operates independently of the processor status and is accessed via a dedicated 1Gbps LAN port. For management within a running system, the Asus Control Center Express software centralises hardware and software monitoring and streamlines IT resource management.
Motherboard connectivity
The Asus Pro WS B850M-ACE SE motherboard offers modern connectivity for high-speed components. The main PCIe 5.0 x16 slot is reinforced with SafeSlot technology for the secure installation of heavy graphics cards. For ultra-fast storage, the manufacturer has provided two M.2 slots with a PCIe 5.0 x4 interface, as well as specialised PCIe 5.0 MCIO and U.2 connectors. Network communication is handled by two ports with speeds of 10Gbps and 2.5Gbps for data-intensive operations. An internal header for a front USB-C port with a transfer speed of 20Gbps is available for connecting peripherals and external drives.
Stable power and 24/7 reliability
The 8+2+1 power stage configuration supplies the processor with a stable stream of power, even under prolonged full load. Each stage is rated for up to 80A, which provides sufficient headroom for multi-core processors. The Digi+ VRM digital controller ensures precise voltage regulation. The reliability of the entire system is supported by an eight-layer PCB, which more effectively dissipates heat from critical components. The reinforced ProCool II power connectors, with lower impedance and better contact, also contribute to overall stability.
Memory performance and AI features
The four DDR5 RAM slots support Dual-Channel mode and a total capacity of up to 192GB. The board works with AMD EXPO profiles, which simplify overclocking to achieve high frequencies of up to 8000MHz. To accelerate local AI calculations and large language models (LLMs), the Asus Pro WS B850M-ACE SE motherboard includes the exclusive AI Cache Boost feature. This technology, available in combination with Ryzen 9000 processors, optimises the paths between the CPU cache and memory, increasing computational performance in specific tasks. The Q-Latch system simplifies the installation of M.2 drives.

Choosing a motherboard
When choosing a motherboard (or mainboard), it is important to pay particular attention to the motherboard's socket type, format and chipset. These parameters are among the most important and ensure the board's compatibility with the processor, expansion cards and other components. The specific socket determines your choice of processor, while the remaining connectors determine which other components you'll need for your future computer.Specifications
