Gaming Motherboard Buying Guide: Chipsets, Form Factors and M.2

The motherboard connects every part of your gaming PC: processor, memory, graphics card, SSDs, networking and USB. It does not make your games faster on its own – but the wrong board can hold you back: the wrong socket, too few M.2 slots, no Wi-Fi, or a graphics card slot that suddenly runs at half bandwidth. In this guide you will learn which socket and chipset match your CPU, what ATX and Micro-ATX mean, and what to look for in PCIe 5.0, M.2, power delivery (VRM) and connectivity. At the end you will find five example motherboards for AMD and Intel.

Transparency: We have not tested these motherboards ourselves. The technical data comes from AMD, Intel and the manufacturers (MSI, ASUS, GIGABYTE) as well as from the checked Amazon.de product pages (as of October 2026). We deliberately do not list prices because they change constantly.

The key criteria at a glance

1. Socket first: AM5 or LGA 1851

The motherboard has to match the processor – that is the most important rule. The current gaming platforms are:

• AMD Socket AM5: for Ryzen 7000, 8000 and 9000. According to AMD, all AM5 motherboards are compatible with all AM5 processors. On boards with a 600 series chipset (e.g. B650, X670), Ryzen 8000 and 9000 may need a BIOS update first.
• Intel Socket LGA 1851: for Intel Core Ultra processors (Series 2), such as the Core Ultra 7 265K. Matching boards use an Intel 800 series chipset (Z890, B860, H810).

Both platforms use DDR5 memory only. Which CPU suits you is covered in our CPU buying guide, the right memory in the RAM buying guide.

2. AMD chipsets: X870E, X870, B850 or B840

The chipset determines how many connections a board can offer and whether CPU overclocking is possible. The main AM5 chipsets according to AMD:

According to AMD, all four support DDR5 overclocking with AMD EXPO. Important: many B850 boards still offer a PCIe 5.0 x16 slot for the graphics card – the MSI MAG B850 Tomahawk MAX WiFi below, for example, per MSI with Ryzen 9000/7000. Always check the spec sheet of the specific board. For most gaming PCs, B850 is the sensible middle ground; X870 is mainly worth it if you want USB4 or more PCIe 5.0 lanes.

3. Intel chipsets: Z890, B860 or H810

On Intel, the differences are clearer according to Intel's spec pages:

According to Intel, all three offer a PCIe 5.0 x16 slot from the CPU. Z890 and B860 also allow a PCIe 5.0 x4 link from the CPU for a fast SSD; for H810, Intel only lists the x16 link. If you want to overclock a "K" CPU like the 265K, you need Z890. If you only want to enable an XMP profile for fast RAM, B860 is enough.

4. Form factor: ATX or Micro-ATX

• ATX (30.5 × 24.4 cm per ASUS/GIGABYTE): the standard size with room for more slots, M.2 sockets and fan headers. Fits most mid-tower cases.
• Micro-ATX (24.4 × 24.4 cm per ASUS): more compact, often cheaper, usually fewer expansion slots. Ideal for smaller cases.
• Mini-ITX: even smaller, usually just two RAM slots and one PCIe slot – for very compact builds.

Before buying, check which form factors your case supports.

5. PCIe 5.0, M.2 slots and shared lanes

The graphics card goes into the top PCIe x16 slot, which is wired directly to the CPU. Fast NVMe SSDs go into M.2 slots – PCIe 5.0 or 4.0 depending on the board. Watch out for two things:

• Number of M.2 slots: three or four slots are common on current ATX boards. How much SSD storage makes sense is covered in the SSD buying guide.
• Shared bandwidth: some slots share lanes. On the GIGABYTE X870 AORUS Elite WIFI7, the graphics card slot drops to x8 according to the manufacturer as soon as one of two specific CPU M.2 slots is populated. On the MSI MAG B850 Tomahawk MAX WiFi, one PCIe slot runs at x2 when the third M.2 slot is in use. Notes like these are in the spec sheet or manual.

With Ryzen 8000 CPUs (APUs), the x16 slot and some M.2 slots run with fewer lanes or only at PCIe 4.0, according to ASUS, MSI and GIGABYTE.

6. Power delivery (VRM) and cooling

The voltage regulators (VRM) around the socket supply the CPU. Manufacturers list phases and current, e.g. "14+2+1 80A". More phases and large heatsinks mainly help with power-hungry CPUs and overclocking. For 65 W CPUs like the Ryzen 5 9600X, a solid mid-range board is enough; for a Core Ultra 7 265K with up to 250 W Maximum Turbo Power (per Intel), a board with strong power delivery is worth it. Also make sure your power supply has enough 8-pin CPU connectors – many boards have two.

7. Wi-Fi, LAN, USB and BIOS Flashback

• Wi-Fi: boards with "WiFi" in the name include a wireless module. According to MSI and ASUS, Wi-Fi 7 needs Windows 11 version 24H2 or later for full functionality.
• LAN: 2.5 Gbit/s is common today; some boards offer 5 Gbit/s.
• USB: for fast external SSDs, USB 20 Gbps or USB4/Thunderbolt 4 is useful.
• BIOS Flashback: lets you update the BIOS from a USB stick – even without a CPU installed. Handy if an older board only recognizes a new CPU after an update.

Which motherboard fits which PC?

• AMD mid-range (Ryzen 5 9600X, Ryzen 7 9700X): B850, ATX or Micro-ATX, at least one PCIe 5.0 M.2 slot.
• AMD high-end (Ryzen 7 9800X3D): B850 with strong VRM, or X870 for USB4 and more PCIe 5.0.
• Intel without overclocking: B860 with XMP support for fast DDR5.
• Intel with a K CPU and overclocking: Z890.
• Compact PC: Micro-ATX board with Wi-Fi, provided your case fits it.

Checklist before you buy

1. Does the socket match the CPU – AM5 or LGA 1851?
2. Does my CPU need a BIOS update on this board? Is there BIOS Flashback?
3. Does the form factor fit my case?
4. Are there enough M.2 slots, and does any slot share lanes with the graphics card?
5. Do I need Wi-Fi, USB4 or Thunderbolt?
6. Does the power supply have enough CPU connectors (often 2× 8-pin)?

FAQ

Does a more expensive motherboard give more FPS?

Usually not directly. FPS are mainly determined by the CPU and graphics card. A pricier board adds more connectivity, stronger power delivery and more convenience.

Do I need PCIe 5.0 for my graphics card?

Not necessarily. Current graphics cards also run in a PCIe 4.0 slot. PCIe 5.0 is mainly about future-proofing – see the graphics card buying guide.

Can I use a B650 board with a Ryzen 9000?

Yes. According to AMD, all AM5 boards work with all AM5 CPUs. On 600 series boards, a BIOS update may be needed.

What is the difference between B850 and X870?

According to AMD, X870 comes with USB4 as standard and PCIe 5.0 for graphics and NVMe. B850 guarantees PCIe 5.0 for NVMe; USB4 is optional.

Can I overclock on a B860 board?

Only the memory (e.g. via XMP). According to Intel, CPU overclocking is only possible with Z890.

Do I need a board with Wi-Fi?

Only if you cannot run a LAN cable. For online games, a cable is usually the more stable choice; a WiFi board is still handy: on all five example boards, the wireless module also adds Bluetooth, e.g. for controllers and headsets.
