Finding the best MSI motherboards under £100 UK 2026 is harder than it looks. The market is crowded, the chipset names are confusing, and one wrong choice means you're stuck with a board that bottlenecks your CPU or won't take the RAM you already own. We've pulled together seven MSI boards spanning AM4, AM5 and Intel LGA 1700 platforms, tested them against real-world build scenarios, and ranked them honestly. No fluff. Whether you're building a first gaming PC, upgrading an ageing system, or just want the most board for your money, this guide covers it.
The MSI B650 GAMING PLUS WIFI sits right at the top of the budget ceiling and earns every penny of it. The 14+2 Duet Rail VRM is the standout spec here. That's a proper power delivery setup that can handle Ryzen 9 class CPUs without thermal throttling or voltage instability. If you're planning a higher-end Ryzen build and want to keep the motherboard cost down, this is the board to get.
You get two M.2 Gen4 slots, which is a meaningful upgrade over the single-slot boards elsewhere in this roundup. Two NVMe drives means you can run your OS and a games drive separately, or use one slot for a fast scratch disk if you're doing video editing. The dual PCIe 4.0 x16 slots also give you multi-GPU or GPU-plus-capture-card flexibility, though most people will only use one.
Wi-Fi 6E is slightly behind the B840's Wi-Fi 7, but in practice the difference is minimal for most home setups. You'd need a Wi-Fi 7 router to see any benefit anyway, and those are still pricey. The 2.5G LAN is present here too. DDR5 support goes up to 6400+ MHz in OC mode, which is a touch lower than the B840's ceiling but still well beyond what most DDR5 kits run at by default.
This board feels the most premium of the group. The heatsinks are chunky, the PCB quality is noticeably good, and the BIOS is well-organised. If you're building something you want to last four or five years without swapping the board out, the B650 GAMING PLUS WIFI is the one to buy.
Not everyone is on the AMD train. If you're building around an Intel Core processor, the MSI B760 GAMING PLUS WIFI is the strongest option in this roundup. It supports Intel 12th, 13th and 14th Gen CPUs on the LGA 1700 socket, so it covers a wide range of processors you might already own or be considering.
The spec sheet is genuinely impressive for the price. Two M.2 Gen4 slots, dual PCIe 4.0 x16, Wi-Fi 6E and 2.5G LAN. That's a feature set you'd expect to pay more for. DDR5 support up to 6800+ MHz in OC mode is solid, and the ATX form factor keeps things roomy inside your case.
We've labelled this one Best for Beginners because the Intel platform tends to be a bit more straightforward for first-time builders. CPU compatibility is well-documented, the BIOS is clean, and MSI's support documentation is thorough. If you've never built a PC before and someone has recommended an Intel Core i5 or i7, this board is a safe, well-specified starting point that won't need replacing any time soon.
The one caveat: Intel's LGA 1700 socket is being replaced by LGA 1851 for Arrow Lake and beyond. So while this board supports three generations of Intel CPUs, it won't take whatever comes next. That's not a dealbreaker at this price, but worth knowing.
Pros
Supports Intel 12th, 13th and 14th Gen CPUs
Dual M.2 Gen4 slots
Wi-Fi 6E and 2.5G LAN included
Beginner-friendly BIOS and setup
ATX size with good expansion options
Cons
LGA 1700 socket won't support next-gen Intel CPUs
Intel platform less future-proof than AM5 right now
The B550M PRO-VDH WIFI is an interesting one. It's an AM4 board in a world that's largely moved on to AM5, but it still makes a strong case for itself if you're upgrading an existing Ryzen system or picking up a Ryzen 5000 CPU at a discount. And those CPUs are genuinely cheap right now.
PCIe 4.0 support is the key spec that keeps this board relevant. You get a PCIe 4.0 x16 slot for your GPU and M.2 Gen4 storage support, which means you're not stuck with the slower Gen3 speeds of the A520 platform. For a gaming build using a mid-range GPU and a fast NVMe drive, that matters.
Wi-Fi is built in, which is a nice touch at this price point. The Micro-ATX form factor keeps things compact without sacrificing too much. You get four DIMM slots for DDR4, which is handy if you want to run 32GB or 64GB of RAM. DDR4 is cheap as chips right now, so that's a genuine advantage over the DDR5 boards.
The honest limitation here is platform longevity. AM4 is end-of-life. Ryzen 5000 is the last CPU generation for this socket. So while the B550M PRO-VDH WIFI is a solid board, you're buying into a platform with no upgrade path beyond what's already available. Fine for a secondary build or a budget gaming rig you plan to use for two or three years. Not ideal if you want to upgrade your CPU in 2027.
Under £50 for a working motherboard that supports Ryzen 5000 CPUs. That's the MSI A520M-A PRO in a nutshell. It's not glamorous. There's no Wi-Fi, no PCIe 4.0, and the USB spec tops out at USB 3.2 Gen 1. But it works, it's reliable, and it's the cheapest way to get a Ryzen 5000 system up and running.
The A520 chipset is AMD's most basic AM4 option. You get PCIe 3.0 rather than 4.0, which means your NVMe drive and GPU are running on the older standard. For gaming at 1080p with a mid-range GPU, you won't notice the difference in practice. The M.2 slot is there for an NVMe drive, and four SATA ports cover any additional storage needs.
DVI and HDMI outputs on the rear I/O are a nice touch for builds using Ryzen APUs with integrated graphics. The Micro-ATX form factor keeps the board compact, and the two DDR4 DIMM slots support up to 64GB of RAM (in 32GB sticks), which is more than enough for any budget build.
Look, this board isn't going to win any awards. But if your budget is genuinely tight and you need a functional AM4 platform for a Ryzen 5 5600 or similar, the A520M-A PRO is the honest choice. It's also a decent option for a secondary PC or a kids' gaming machine where you don't need cutting-edge specs. Just don't expect to upgrade the CPU beyond Ryzen 5000 series.
Buying Guide: What to Look For in the Best MSI Motherboards Under £100
Choosing a motherboard is mostly about matching the right platform to your needs. Get that wrong and everything else falls apart. Here's what actually matters when you're shopping in this price range.
Platform: AM4, AM5 or Intel LGA 1700? This is the first decision. AM4 (A520, B550) is the older AMD platform. Cheap boards, cheap CPUs, cheap DDR4 RAM. Great for tight budgets, but no upgrade path beyond Ryzen 5000. AM5 (A620, B650, B840) is AMD's current platform. Supports Ryzen 7000, 8000 and 9000 CPUs, requires DDR5 RAM, and will have upgrade options for years to come. Intel LGA 1700 (H610, B760) covers 12th, 13th and 14th Gen Intel CPUs. Solid platform, but being replaced by LGA 1851 for future Intel generations.
Chipset tier matters. Within each platform, the chipset determines what features you get. A520 and H610 are entry-level: limited overclocking, fewer PCIe lanes, slower M.2 slots. B550, B650, B760 and B840 are mid-range: better VRMs, PCIe 4.0 support, more M.2 slots, memory overclocking. For gaming builds, aim for a B-series chipset if you can stretch to it.
VRM quality for CPU compatibility. The VRM (voltage regulator module) is what powers your CPU. A weak VRM on a high-end CPU means thermal throttling and instability. The B650 GAMING PLUS WIFI's 14+2 phase VRM is the strongest here. The A520 and H610 boards are fine for Ryzen 5 or Intel Core i5 class CPUs, but don't pair them with a Ryzen 9 or Core i9.
M.2 slots and storage. One M.2 Gen4 slot is the minimum for a modern build. Two slots (as on the B650 and B760) give you room for an OS drive and a games drive separately. Gen4 is faster than Gen3, though for most gaming workloads the difference is modest. If you're doing video editing or large file transfers, Gen4 makes a bigger difference.
Wi-Fi: built-in or add-on? Boards with built-in Wi-Fi cost a bit more, but a separate Wi-Fi PCIe card costs £20 to £40 anyway. If your PC won't be near a router, factor Wi-Fi into your board choice from the start. Wi-Fi 7 (on the B840) is the newest standard. Wi-Fi 6E (on the B650 and B760) is still very fast for most home setups.
Form factor. ATX boards are larger and offer more expansion slots. Micro-ATX is more compact and fits smaller cases. Both are fine for most builds. Just check your case supports the form factor before buying.

Frequently Asked Questions
Absolutely. The MSI PRO B760M-P DDR4 offers excellent value with support for 12th and 13th gen Intel processors, dual M.2 slots, and solid VRM cooling. You won't get all the bells and whistles of premium boards, but for most builders it's more than enough.
It depends on your processor choice. Intel B760 boards like the PRO B760M-P offer great value for 12th/13th gen chips. AMD AM5 boards cost a bit more but support DDR5 and offer a longer upgrade path with future Ryzen processors. AM4 boards are cheapest but the platform is end-of-life.
DDR4 is currently better for strict budgets. DDR5 motherboards and RAM cost more, and real-world performance gains are minimal for most users. The MSI PRO B760M-P DDR4 offers better overall value than DDR5 alternatives that push you over £100.
B-series chipsets (B760, B650, B550) support RAM overclocking and AMD processor overclocking, but not Intel CPU overclocking. That requires Z-series boards which cost significantly more. For most budget builders, the stock performance is perfectly adequate anyway.
Micro-ATX boards are smaller and typically have fewer expansion slots and features. They're perfect for compact builds and often cheaper. ATX boards offer more PCIe slots, M.2 slots, and better VRM cooling. For single-GPU gaming builds, Micro-ATX is usually fine and saves money.
