Building a multi-GPU setup can significantly boost gaming and creative workloads. However, choosing the right motherboard is crucial, especially when working within a budget. The AMD B650 chipset offers a compelling balance of features and affordability, making it a popular choice for budget-conscious enthusiasts aiming for multi-GPU configurations.

Understanding the B650 Chipset

The AMD B650 chipset is designed for mainstream AMD Ryzen processors. It supports PCIe 4.0, DDR5 memory, and multiple storage options. While not as feature-rich as higher-end chipsets like X670, B650 motherboards provide essential features for most users, including multi-GPU support in some models.

Multi-GPU Support on B650 Motherboards

Multi-GPU configurations, typically using AMD's CrossFire or NVIDIA's SLI, require specific motherboard features. Many B650 motherboards support AMD CrossFire, but support for NVIDIA SLI is limited or absent. It's essential to verify the motherboard specifications before purchasing for multi-GPU setups.

Key Features to Consider

  • PCIe Slots: Ensure the motherboard has multiple PCIe x16 slots capable of running GPUs at full bandwidth.
  • Power Delivery: Adequate VRMs are necessary to support multiple GPUs and CPU overclocking.
  • Cooling Solutions: Good heatsinks and airflow are vital for maintaining stable operation under load.
  • Expansion and Connectivity: Sufficient USB, M.2 slots, and SATA ports for other components.
