Budget motherboard shopping has never been more competitive, and MSI continues to punch well above its weight in the sub-£24.85 bracket. Whether you are putting together a first gaming PC, upgrading an ageing office machine, or building a compact media centre, a well-chosen MSI board can give you a stable, feature-rich foundation without draining your component budget. Since last year, MSI has refreshed several of its PRO and MAG series boards with improved VRM layouts, better M.2 slot coverage, and updated BIOS interfaces that make overclocking and memory tuning far more accessible to newcomers. AMD AM4 and AM5 options have expanded, while Intel LGA1700 boards have dropped noticeably in price as the platform matures. This guide covers the five best MSI motherboards available in the UK for under £24.85 comparing key specs, real-world suitability, and honest pros and cons so you can spend your money wisely.
Best Overall: MSI PRO B550M-VC WiFi. It balances AM4 compatibility, built-in Wi-Fi, and solid VRM quality at a price that leaves room for a decent GPU or CPU upgrade.
Best Value: MSI PRO B450M-A Pro Max. An outstanding entry-level board for Ryzen builders who want reliable performance and broad CPU support without paying for features they will never use.

Every board in this guide was assessed against a consistent set of criteria relevant to UK budget builders. Pricing was verified against major UK retailers including Amazon UK, Scan, Overclockers, and Ebuyer, with only boards consistently available under £75 considered for inclusion. VRM quality was evaluated using publicly available phase counts and power stage ratings, cross-referenced with independent thermal testing from established hardware review sites. CPU compatibility lists were checked directly against MSI's official support pages. BIOS quality was assessed based on documented user experience and the availability of regular firmware updates. Feature sets were compared within the context of each board's price and target use case, rather than against more expensive competitors. Boards were selected to cover both AMD and Intel platforms, and to represent a range of use cases from basic office builds to capable gaming systems.
The most important decision when buying a budget motherboard is matching the socket and chipset to your CPU. AMD's AM4 socket covers Ryzen 2000 through 5000 series processors, and it is supported by A320, A520, B450, B550, and X570 chipsets. For a budget build, B450 and B550 offer the best balance of features and price. A520 is cheaper but removes CPU overclocking. Intel's LGA1700 socket covers 12th and 13th Gen Core processors, with H610, B660, B760, and Z790 chipsets. H610 is the entry point, B760 adds memory overclocking and more features. Never buy a board without confirming your CPU is on the manufacturer's supported CPU list, and always check whether a BIOS update is required before the CPU will POST.
The voltage regulator module powers your CPU, and a weak VRM will throttle performance under sustained loads or, in extreme cases, cause instability. Budget boards use fewer phases and lower-rated power stages than premium boards. For a Ryzen 5 or Core i5 at stock settings, a 4+2 or 6+2 phase VRM is adequate. For a Ryzen 7 or Core i7, look for at least an 8+2 phase design. Avoid pairing a Ryzen 9 or Core i9 with the cheapest boards in any range.
Four DIMM slots are preferable to two because they give you more upgrade flexibility and allow you to run dual-channel with two sticks while leaving room for expansion. Check the maximum supported memory speed with XMP enabled, as budget boards sometimes list a theoretical maximum that requires specific memory kits to achieve. For gaming and general use, DDR4-3200 or DDR4-3600 is the sweet spot.
At minimum, look for one M.2 slot and four SATA ports. If you plan to use a PCIe 4.0 NVMe drive, confirm the board's M.2 slot supports PCIe 4.0, as many budget boards are limited to PCIe 3.0. Two M.2 slots are worth prioritising if you plan to run multiple NVMe drives without using SATA adapters.
MSI is one of the three dominant motherboard manufacturers globally, alongside ASUS and Gigabyte. The brand has a strong reputation for build quality, BIOS stability, and long-term firmware support. MSI's PRO series targets budget and office builders with reliable, no-frills designs, while the MAG and MEG series cater to gamers and enthusiasts. For budget builds, MSI's PRO series boards consistently offer competitive features and reliable performance. The brand is well regarded by independent reviewers and has a strong track record for honouring warranties in the UK market.
Both brands produce excellent motherboards across all price points, and the honest answer is that neither is categorically better. ASUS tends to offer slightly more premium aesthetics and has a strong reputation for its ROG and TUF Gaming lines. MSI's PRO and MAG series boards are often more competitively priced at the budget end and have a strong BIOS reputation. For sub-£24.85 builds, MSI's PRO series frequently offers better value than comparable ASUS Prime boards. The best choice depends on the specific model, its price at the time of purchase, and the features it offers for your particular build.
HP and MSI serve fundamentally different markets. HP manufactures pre-built computers and laptops, and while HP does produce some commercial motherboards for its own systems, these are not sold as standalone retail products for custom PC builds. MSI manufactures retail motherboards designed for custom PC assembly. If you are building a PC from components, MSI is the relevant choice. If you are buying a complete pre-built system, HP and MSI both offer competitive options in their respective product lines.
Across the six boards reviewed, the MSI PRO B550M-VC WiFi earns the overall recommendation for most UK buyers. It combines integrated Wi-Fi 5, dual M.2 slots with PCIe 4.0 support, and broad Ryzen 5000 compatibility at a price that consistently sits below £24.85. For the majority of budget AMD builds, it covers every meaningful base without compromise. If your budget is tighter still, the MSI PRO B450M-A Pro Max delivers a mature, stable platform with Ryzen 5000 support at a lower outlay, making it the best value pick for builders who do not need wireless connectivity or PCIe 4.0 storage. Intel builders should look at the PRO B760M-P DDR4 for a capable, feature-rich platform, or the PRO H610M-G DDR4 if the budget is very strict. The MAG B550M Mortar WiFi is worth monitoring for price drops, as it offers a level of quality that genuinely exceeds its current price when available under £24.85.
MSI is one of the most established motherboard manufacturers in the world, with a strong reputation for build quality, BIOS stability, and long-term firmware support. The brand's PRO series is particularly well regarded in the budget segment, offering reliable performance and consistent CPU compatibility updates. Independent hardware reviewers consistently rate MSI boards as competitive with ASUS and Gigabyte across all price points.
Neither brand is definitively better across the board, as both produce strong products at every price point. In the sub-£75 bracket specifically, MSI's PRO series boards frequently offer more features per pound than comparable ASUS Prime boards, particularly in areas like VRM quality and M.2 slot count. The best approach is to compare specific models at their current UK retail prices rather than choosing a brand outright.
Yes, MSI extended Ryzen 5000 series support to its B450 and A520 boards through BIOS updates, which was not guaranteed when those chipsets launched. However, you may need to install an older Ryzen processor first to update the BIOS before a Ryzen 5000 chip will POST, unless the board ships with a BIOS version that already includes the necessary support. Always check MSI's official CPU support list for your specific board before purchasing.
The main practical differences are PCIe 4.0 support and slightly improved VRM designs on B550 boards. B550 offers PCIe 4.0 on the primary M.2 slot and the primary PCIe x16 slot, enabling faster NVMe drives and future GPU compatibility. B450 is limited to PCIe 3.0 throughout. Both chipsets support Ryzen 5000 processors with a BIOS update, and both allow memory overclocking. If you plan to use a PCIe 4.0 NVMe drive, B550 is worth the modest price premium.
MSI provides a three-year manufacturer's warranty on its motherboards sold in the UK, which is standard across the PRO, MAG, and MEG product lines. Warranty claims can be processed through MSI's UK support portal or via the retailer depending on when the fault occurs. Keeping proof of purchase is essential, as MSI requires it for all warranty claims.
