MSI has spent the past decade building a reputation as one of the most reliable motherboard manufacturers on the market, offering boards that punch above their price point across both AMD and Intel platforms. Whether you are building a budget gaming rig around an Intel Core i5 or pushing a Ryzen 9 into a mid-range workstation, there is an MSI board under £300 that fits the brief. Since last year, MSI has refreshed its AMD lineup significantly, with the B850 and X870 chipsets arriving to support DDR5 and PCIe 5.0, while the Intel side has seen the Z890 and B760 boards mature with better VRM designs and improved Wi-Fi 7 integration. This roundup covers six of the best MSI motherboards available in the UK right now, all priced under £300, spanning micro-ATX and full ATX form factors, AMD AM4, AM5, and Intel LGA1700 sockets. It is aimed at first-time builders, upgraders, and anyone who wants a dependable board without overspending.
Quick Verdict
Best Overall: MSI MAG B850 TOMAHAWK MAX WIFI. It offers the best balance of modern features, DDR5 support, PCIe 5.0 readiness, and a robust VRM for the money, making it the smartest mid-range AMD AM5 purchase in 2025.
Best Value: MSI B760 GAMING PLUS WIFI. For Intel builders who want a full ATX board with Wi-Fi 6E, solid VRM headroom, and broad CPU compatibility across three generations, this board delivers exceptional value well under £150.
The MAG B850 TOMAHAWK MAX WIFI is MSI's most compelling mid-range AMD board for 2025, and it earns the top spot in this roundup with considerable ease. It sits on the AM5 socket and uses AMD's newer B850 chipset, which brings PCIe 5.0 support for both the primary graphics slot and M.2 storage, USB4 connectivity at the rear, and Wi-Fi 7 with Bluetooth 5.4 built in. All of that lands at a price that, until very recently, you would have expected to pay for a B650 board with fewer features.
The board is designed for builders who want to run a Ryzen 7000, 8000, or 9000 series processor and are thinking ahead. The 14+2+1 phase VRM is robust enough to handle a Ryzen 9 9950X at stock settings without thermal throttling, and with a decent cooler you can push moderate overclocks on mid-range chips without issue. Four DDR5 DIMM slots support up to 256 GB of memory and can run at 6400 MHz or beyond with XMP or EXPO profiles enabled, which is useful for content creators and anyone running memory-hungry workloads.
Connectivity is a genuine highlight. The rear panel includes a USB4 Type-C port running at 40 Gbps, several USB 3.2 Gen 2 Type-A ports, 2.5 Gigabit Ethernet, and the Wi-Fi 7 antenna connections. There are four M.2 slots in total, two of which are PCIe 5.0 capable, meaning you can install the fastest NVMe drives available without any bottleneck. Six SATA ports round out storage options for those still running mechanical drives or older SSDs.
The aesthetics follow the Tomahawk tradition: understated black PCB with subtle RGB accents rather than the garish lighting found on some competitors. The BIOS is MSI's Click BIOS 5, which is one of the more approachable interfaces available, particularly for first-time builders who want to enable XMP without wading through confusing menus.
Who is it for? Primarily Ryzen 9000 and 7000 series builders who want a future-proof platform without spending X870E money. It is equally suited to a gaming PC, a home workstation, or a creative editing machine. The only real limitation is that it lacks the extreme overclocking headroom of the X870 or X670E chipsets, but for the vast majority of users that will never matter.
Verdict: The best all-round MSI board under £300 in 2025. Exceptional feature density, solid VRM, and genuinely modern connectivity make it the default recommendation for AMD AM5 builds at this price.

How We Picked
Every board in this roundup was evaluated against a consistent set of criteria relevant to UK builders in 2025. We started with compatibility: does the board support current and near-future processors on its socket, and does it offer a credible upgrade path? Next, we examined VRM quality, looking at phase count, component ratings, and thermal performance under sustained CPU loads, because a weak VRM is the most common cause of instability in budget builds.
Connectivity was assessed in terms of both rear panel ports and internal headers, with particular attention to USB4, M.2 slot count, and networking capabilities. We also considered BIOS quality and ease of use, since a confusing BIOS can undermine an otherwise excellent board for less experienced builders. Finally, value was assessed relative to competing boards at the same price point, not just within the MSI range but across the market. Only boards that offered a genuinely competitive feature set for their price were included.
Buying Guide
Choosing the Right Socket and Chipset
The single most important decision when buying a motherboard is socket compatibility. AMD AM5 boards support Ryzen 7000, 8000, and 9000 series processors and use DDR5 memory exclusively. Intel LGA1700 boards support 12th, 13th, and 14th generation Core processors and are available in both DDR4 and DDR5 variants. If you are building from scratch, AM5 is generally the better long-term investment because AMD has committed to AM5 socket support through at least 2027, giving you more CPU upgrade options without changing the motherboard.
Within each platform, the chipset determines what features are available. For AMD, B840 is the entry level, B650 and B850 are mainstream, and X870 and X670E are enthusiast-grade. For Intel, B760 is mainstream and Z790 is the overclocking-focused option. For most builders, a B-series chipset is sufficient: the main things you lose compared to X-series are some overclocking headroom, fewer PCIe lanes, and occasionally a reduced M.2 slot count.
VRM Quality Matters More Than You Think
The voltage regulator module powers the CPU, and a weak VRM will throttle performance under sustained loads even if the processor is well within its rated TDP. Look for at least a 10+2 phase design for Ryzen 5 and Core i5 processors, and a 14+2 or higher for Ryzen 9 and Core i9 chips. MSI publishes VRM specifications in its product datasheets, and the Tomahawk and higher-tier boards consistently use higher-quality components than the entry-level options.
Memory Support and Speed
All AM5 boards use DDR5, and all current LGA1700 boards in this roundup also use DDR5. When comparing boards, check the maximum supported memory speed with XMP or EXPO profiles enabled, as this varies between chipsets. Higher memory speeds benefit AMD processors more than Intel ones due to the Infinity Fabric architecture, so if you are building an AMD system, prioritising memory speed support is worthwhile. Also check the maximum RAM capacity: B650 boards typically support 128 GB while B850 and X870 boards support 256 GB.
Connectivity: What to Look For
Wi-Fi is now standard on most mid-range and above boards, but the version matters. Wi-Fi 6E offers tri-band support and is widely available; Wi-Fi 7 adds multi-link operation for lower latency and higher throughput, and is found on B850 and X870 boards in this roundup. For wired networking, 2.5 Gigabit Ethernet is the baseline, with 5G and 10G options available on higher-end boards. USB4 at 40 Gbps is increasingly important for external SSD docks, Thunderbolt 4 peripherals, and high-resolution displays connected via USB-C.
Form Factor Considerations
Most of the boards in this roundup are full ATX, measuring 305 x 244 mm, which fits any mid-tower or full-tower case. The MEG X670E ACE is E-ATX at 305 x 264 mm, which requires a case specifically rated for E-ATX. If you are building in a smaller case, check whether a Micro-ATX or Mini-ITX board is available for your chosen platform, though these are not covered in this roundup.
Is MSI a Good Brand?
MSI is consistently rated among the top three motherboard manufacturers alongside ASUS and Gigabyte. The brand offers strong build quality, a well-regarded BIOS interface, and competitive warranty support in the UK. Compared to ASUS, MSI boards are often slightly better value at the mid-range, while ASUS tends to have a stronger premium tier. HP does not manufacture motherboards for the consumer market in the traditional sense, so a direct comparison is not meaningful. For quality, reliability, and value, MSI is an excellent choice for any budget.
Final Verdict
The MSI MAG B850 TOMAHAWK MAX WIFI is the overall winner in this roundup. It combines Wi-Fi 7, USB4 40 Gbps, four M.2 slots with PCIe 5.0 support, a robust 14+2+1 phase VRM, and full Ryzen 9000 series compatibility at a price that represents genuine value in 2025. It is the board we would recommend to the majority of readers building or upgrading an AMD system right now, and it will remain relevant well into the next CPU generation. For Intel builders, the B760 GAMING PLUS WIFI earns the best value award with its broad CPU compatibility, Wi-Fi 6E, and PCIe 5.0 M.2 slot at well under £150. Both boards exemplify what MSI does best: delivering feature-rich, well-built motherboards at prices that make the competition work harder.
