Price Comparison
The ASRock B650I Lightning WiFi is priced at $169.99, making it about 21% more expensive than the MSI PRO B650-S, which retails for $139.99. This price difference may influence budget-conscious consumers who are looking for high-quality performance without breaking the bank. The MSI PRO B650-S offers a robust feature set at a lower price point, making it an attractive choice for users who want to maximize their investment.
Design and Form Factor
The ASRock B650I Lightning WiFi features an ultra-compact Mini-ITX design, which is ideal for small form factor builds and tight spaces. In contrast, the MSI PRO B650-S follows a standard ATX layout, providing more expandability options for users who may prioritize additional PCIe slots or memory channels. If you're building a compact system, the ASRock's Mini-ITX form factor is a clear advantage. However, for users needing versatility in their setups, the MSI's ATX form provides more room for future upgrades.
Power Delivery and Efficiency
The ASRock B650I Lightning WiFi employs an advanced 8+2+1 power delivery system, which ensures exceptional stability and efficiency, particularly for overclocking scenarios. On the other hand, the MSI PRO B650-S features a 12+2 duet rail power system, which also enhances performance, especially with demanding applications. Both motherboards are designed with efficient power delivery systems, but the MSI’s higher phase count may offer slightly better performance under heavy loads, making it suitable for power users.
Memory Support
The ASRock B650I Lightning WiFi supports dual-channel DDR5 memory, optimized for overclocked speeds up to 7200+ MHz. Meanwhile, the MSI PRO B650-S also supports DDR5 memory with similar overclocking capabilities. Both motherboards provide excellent memory performance, but the ASRock's optimized setup may give it a slight edge for users looking to push their memory to its limits.
Connectivity Options
Connectivity is a strong point for both motherboards. The ASRock B650I Lightning WiFi includes a comprehensive suite featuring 2.5G LAN, Intel WiFi 6E, and multiple USB 3.2 Gen2 ports. The MSI PRO B650-S also offers 2.5G LAN and WiFi 6E, along with a range of USB ports including USB 3.2 Gen 2 and HDMI/DP outputs. While both motherboards provide excellent connectivity, the ASRock’s additional USB Type-C options may appeal to users with modern peripherals, giving it a slight advantage in this category.
Storage Capabilities
The ASRock B650I Lightning WiFi offers dual M.2 slots supporting both PCIe 5.0 and PCIe 4.0, as well as two SATA3 ports for added flexibility in storage configurations. Similarly, the MSI PRO B650-S also includes M.2 slots and SATA 6Gb/s support, allowing users to install high-speed NVMe SSDs alongside traditional hard drives. Both motherboards excel in storage options, but the ASRock's support for the next-generation PCIe 5.0 standard may appeal to those looking to future-proof their systems.
Audio Experience
The audio capabilities of the ASRock B650I Lightning WiFi are enhanced by a Realtek ALC897 7.1 CH HD Audio Codec, paired with Nahimic Audio technology for immersive sound quality. The MSI PRO B650-S does not specify its audio codec, but it is designed for productivity and multimedia tasks. If audio quality is a significant factor for your build, the ASRock’s dedicated audio enhancements provide a tangible benefit for gamers and media enthusiasts alike.
Which should you buy?
Ultimately, the choice between the ASRock B650I Lightning WiFi and the MSI PRO B650-S comes down to your specific needs and preferences.
