Best ASUS Motherboards Under £100

Yes, the ASUS Prime B450M-K II at £69.34 offers excellent value for budget builds. It supports Ryzen processors, DDR4 memory, and includes two M.2 slots. While it lacks Wi-Fi and advanced features, it's reliable for basic gaming and everyday computing.

B550 supports PCIe 4.0 for faster storage and graphics cards, while B450 maxes out at PCIe 3.0. B550 also offers better power delivery for newer Ryzen processors. If you're building a budget system with older Ryzen chips, B450 is perfectly adequate.

No, all ASUS motherboards genuinely under £100 use DDR4 memory. DDR5 motherboards start around £115-180. The good news is DDR4 is significantly cheaper and still performs well for budget gaming and productivity builds.

Yes, but with limitations. The B450 and B550 chipsets support CPU and memory overclocking, though power delivery on sub-£100 boards is basic. You can achieve modest overclocks, but don't expect to push high-end Ryzen chips to their limits.

AM4 is the best choice for budget builds under £100. It supports affordable Ryzen 5000 series processors with excellent performance. AM5 motherboards with DDR5 start above £100, making them unsuitable for strict budget builds.
