- Provides versatile storage options with six SATA3 ports, one Ultra M.2 (PCIe Gen3 x4), and one M.2 (PCIe Gen3 x2 & SATA3).
👎 Cons
- The PCI-Express 3.0 x16 slots operate at varying speeds (x8, x4, x2), which might limit the bandwidth for certain configurations.
- Supports 105W water cooling for Pinnacle Ridge, but only 95W for Summit Ridge and 65W for Raven Ridge, indicating varied thermal limits.
- While supporting DDR4 3533+ (OC), achieving these speeds may depend on the specific CPU and memory kit used.
- The B450 chipset, while capable, is not the latest generation, which might mean missing out on some newer features like PCIe Gen 4.
- Only supports Microsoft Windows 10 64-bit, which may be a limitation for users with other operating system preferences.
