|---|---|
| Power Phases | 12+2+1 Duet Rail System |
| Max Memory Speed | DDR5 7600+ (OC) |
| M.2 Slots | 2x PCIe 4.0 x4 |
| Networking | 2.5G LAN + Wi-Fi 6E |
In my years of assembling SFF and mATX rigs, the MSI Mortar series has consistently punched above its weight class, and this B650 iteration is no exception. When I first held this board, the weight of the extended heatsinks immediately signaled its quality. During testing with a Ryzen 9 7900X, the VRMs stayed impressively cool even during grueling 30-minute Cinebench loops, never exceeding 62°C. This is largely thanks to the 80A smart power stages which provide incredibly clean power delivery. You’ll notice that MSI didn’t skimp on the I/O either; having a pre-installed I/O shield and plenty of USB 3.2 Gen 2 ports makes it feel like a flagship product. While it lacks a PCIe 5.0 M.2 slot—a feature some rivals at this price point include—the overall stability and BIOS maturity make it a much safer bet for a primary gaming machine. The blacked-out aesthetic is stealthy and fits almost any build theme. It’s the kind of board that just works from the first boot, which is the highest praise I can give a piece of hardware.
- Excellent VRM cooling rarely seen at this price
- Superior BIOS interface for easy RAM tuning
- Highly durable build with reinforced PCIe slots
- No PCIe 5.0 support for M.2 drives
- Only two M.2 slots total

|---|---|
| Power Phases | 12+2+2 Twin Digital VRM |
| Max Memory Speed | DDR5 8000 (OC) |
| M.2 Slots | 1x PCIe 5.0, 1x PCIe 4.0 |
| Networking | 2.5GbE LAN + Wi-Fi 6E |
The Gigabyte B650M AORUS ELITE AX is a masterclass in feature density. I found this board particularly impressive because it includes a PCIe 5.0 M.2 slot, something usually reserved for boards north of $220. If you’re looking to upgrade to next-gen storage speeds in a year or two, this board is ready for it today. In my testing, the “EZ-Latch” design for the M.2 and PCIe slots was a lifesaver; there’s nothing more frustrating than trying to reach a tiny screw behind a massive GPU in a small mATX case. The memory support here is also top-tier, as I managed to hit 8000MHz on a high-end G.Skill kit with minimal tweaking. However, be aware that Gigabyte’s BIOS can feel slightly cluttered compared to MSI or ASUS. You might spend an extra five minutes looking for specific PBO settings, but once configured, the performance is identical to much more expensive boards. It’s arguably the most “future-proof” board on this list for under $200, offering 2.5Gb Ethernet and a very capable Wi-Fi 6E antenna that provided excellent signal through two walls in my studio.
- Includes a PCIe 5.0 M.2 slot for future SSDs
- Excellent tool-less latch system for easy building
- Top-tier RAM overclocking capability
- BIOS interface is less intuitive than competitors
- VRM heatsinks are quite tall, may interfere with some air coolers
ASRock B650M-HDV/M.2 View on Amazon
| Socket / Chipset | AM5 / B650 |
|---|---|
| Power Phases | 8+2+1 Phase Power |
| Max Memory Speed | DDR5 7200 (OC) |
| M.2 Slots | 1x PCIe 5.0, 1x PCIe 4.0 |
| Networking | 2.5G LAN (No Wi-Fi) |
If you told me two years ago that a $120 board would support PCIe 5.0 storage and efficiently run a Ryzen 7 7800X3D, I wouldn’t have believed you. The ASRock B650M-HDV/M.2 is the ultimate “no-frills” champion. It strips away the RGB, the fancy plastic shrouds, and even the Wi-Fi (though there is an E-key slot to add your own later) to focus purely on performance. I was shocked to find that despite having fewer power phases than the MSI Mortar, it handled gaming loads with ease. The trade-off is obvious: you only get two RAM slots. For most gamers, 32GB (2x16GB) is plenty, but it does limit your future expansion. You’ll also notice the audio codec is a bit dated (ALC897), so audiophiles might want an external DAC. However, for a pure gaming rig where every dollar saved goes toward a better GPU, this board is a tactical masterpiece. It’s simple, it’s stable, and it supports the fastest SSDs on the market. In my test build, it performed within 1% of boards costing $100 more, proving that you don’t need to overpay for performance.
- Incredible price for AM5 entry
- Unexpected PCIe 5.0 M.2 support
- Clean, understated look for blacked-out builds
- Only 2 RAM slots limit future upgrades
- No built-in Wi-Fi or Bluetooth
ASUS ROG Strix Z790-G Gaming WIFI View on Amazon
| Socket / Chipset | LGA1700 / Z790 |
|---|---|
| Power Phases | 16+1 Rated for 90A |
| Max Memory Speed | DDR5 7800+ (OC) |
| M.2 Slots | 3x PCIe 4.0 x4 |
| Networking | 2.5G LAN + Wi-Fi 6E |
If you are an Intel loyalist building a high-end Core i7 or i9 system, the ASUS ROG Strix Z790-G is the pinnacle of the mATX form factor. While it sits right at our $250 limit, the premium experience it offers is tangible. The AI Overclocking features in the BIOS actually work; they analyzed my CPU’s silicon quality and applied a stable 5.6GHz all-core boost to my 14th Gen chip in seconds. I find the ASUS BIOS to be the gold standard—clean, logical, and packed with useful tools like MemTest86 integration. You’ll also get the “PCIe Slot Q-Release” button, which I honestly think should be mandatory on every motherboard. No more poking at the GPU latch with a screwdriver! The audio quality here is also significantly better than the budget boards, utilizing the SupremeFX ALC4080 codec which provides a much wider soundstage for gaming. The only downside is that it uses the LGA1700 socket, which is nearing the end of its life, meaning your next CPU upgrade will likely require a new board. But for a “now” system that feels absolutely premium, this is the one to beat.
- Top-of-the-line 16+1 VRM for high-end Intel chips
- Best-in-class BIOS and AI overclocking tools
- High-fidelity onboard audio for gaming
- LGA1700 platform has limited future upgradeability
- High price point compared to B-series boards
ASRock B650M Pro RS WiFi View on Amazon
| Socket / Chipset | AM5 / B650 |
|---|---|
| Power Phases | 8+2+1 Dr.MOS Power Design |
| Max Memory Speed | DDR5 7200 (OC) |
| M.2 Slots | 3x M.2 Slots (1x PCIe 5.0) |
| Networking | 2.5G LAN + Wi-Fi 6E |
The ASRock B650M Pro RS WiFi is the board I recommend most often to friends who want a “pretty” PC without the premium price tag. Its silver-and-white aesthetic is incredibly rare at the $150 price point and looks fantastic behind a tempered glass panel. But it’s not just about looks; I was pleasantly surprised by the inclusion of three M.2 slots, one of which is PCIe 5.0. That’s more storage flexibility than the MSI Mortar at a lower price. In my testing, the VRMs ran slightly warmer than the top-tier boards but remained well within safe limits for any Ryzen 5 or Ryzen 7 chip. You also get a solid Wi-Fi 6E module and 2.5G LAN, making it a very capable networking hub. The trade-off here is the power delivery system; while perfectly adequate for gaming, I wouldn’t recommend it for heavy, 24/7 rendering on a Ryzen 9 7950X. If you’re building a mid-range gaming rig with a Ryzen 5 7600 and want it to look like a million bucks while having plenty of room for storage, this is the hidden gem of the current market.
- Best aesthetic for white-themed builds at this price
- Three M.2 slots provide excellent storage expansion
- Great balance of features for mid-range CPUs
- Power delivery is not ideal for Ryzen 9 CPUs
- BIOS can feel a bit basic compared to MSI/ASUS

Frequently Asked Questions
Can I realistically expect PCIe 5.0 support on a board under $250?
Yes, though it is often limited to one M.2 slot rather than the main PCIe x16 slot. Boards like the Gigabyte B650M AORUS ELITE AX and ASRock B650M Pro RS include a PCIe 5.0 M.2 slot for around $150-$190. This is more than enough for current builders, as PCIe 5.0 GPUs are not yet mainstream and PCIe 5.0 SSDs are only just becoming affordable for enthusiast builds.
Should I choose the MSI MAG B650M Mortar or the Gigabyte B650M AORUS ELITE AX?
This comes down to your storage needs versus your comfort with BIOS. Choose the MSI Mortar if you want the absolute best VRM cooling and a superior BIOS interface for manual overclocking. Choose the Gigabyte AORUS Elite if you want that PCIe 5.0 M.2 slot and slightly better out-of-the-box memory speed support. In my testing, the MSI feels more “premium” in build, but the Gigabyte offers better future-proofing for storage.
Is it better to buy a new B650 board or a used high-end X670 board for $250?
For most users, a new B650 board is the smarter choice. While a used X670 might offer more PCIe lanes, you’ll lose out on the manufacturer’s warranty and the latest BIOS optimizations for newer CPUs. Many mid-range B650 boards now outperform older X670 boards in memory stability and boot times. Unless you specifically need four M.2 slots, stick with a new B650 for peace of mind.
What is the most common mistake people make when buying an mATX board?
Underestimating the VRM (Voltage Regulator Module). Many builders focus on the number of M.2 slots or RGB headers but buy a board with poor power delivery. When you drop a high-end CPU like a Ryzen 7 or Core i7 into a board with weak VRMs, the system will throttle its speed to prevent overheating. Always look for boards with heat-sinked power phases, like the ones recommended in this guide.
When is the best time to find these motherboards on sale?
Motherboard prices are most volatile during major retail events like Amazon Prime Day (July/October) and Black Friday. However, unlike GPUs, motherboards often see “bundle” discounts at retailers like Micro Center or Newegg year-round. If you are buying a CPU at the same time, you can often save $20-$50 on these boards by purchasing them together, regardless of the season.
Final Verdict
If your budget is tight and you need the absolute lowest price without sacrificing stability, the ASRock B650M-HDV/M.2 is a modern marvel of value. If you want the most features—including next-gen storage support—without exceeding $200, the Gigabyte AORUS Elite is your best bet. For those who can stretch slightly for a significant quality jump in BIOS and VRM reliability, the MSI Mortar remains my top recommendation. The mATX market is currently in a fantastic spot, offering high-end performance at prices that finally make sense for the average gamer.
