MSI MAG X870E GAMING MAX WIFI — AMD X870E ATX for Socket AM5 with USB4 and Wi-Fi 7
AMD X870E / Socket AM5USB4 40 Gbps Type-C3 x M.2, one PCIe 5.0Wi-Fi 7 + Realtek 5Gb LAN
The MSI MAG X870E GAMING MAX WIFI is a full-size ATX motherboard on AMD’s flagship X870E chipset for Socket AM5, bringing USB4 at 40 Gbps and a 5Gb wired network port to a gaming board rather than a workstation one. It carries the part number 7E86-001R (EAN 4711377407199) and supports AMD Ryzen 9000, 8000 and 7000 Series processors, with four DDR5 UDIMM slots taking up to 256 GB and rated to 8200 MT/s when overclocked with AMD EXPO. Storage covers three M.2 slots — the first at PCIe 5.0 x4, the other two at PCIe 4.0 x4 — plus four SATA 6 Gb/s ports. Wireless is Wi-Fi 7 across 2.4, 5 and 6 GHz with Bluetooth 5.4, and the rear panel adds a 20 Gbps Type-C port alongside the USB4 one. Typically in stock with fast delivery across Cyprus.
Compatibility — check before buying:
Despite the reseller listings that describe this board as ITX, it is full ATX at 304.8 x 243.84 mm — do not size a case around an incorrect listing. The three M.2 slots differ in source and length support: M.2_1 is PCIe 5.0 x4 from the CPU (2280 / 2260), M.2_2 is PCIe 4.0 x4 from the chipset and takes 22110 drives, M.2_3 is PCIe 4.0 x4 from the chipset. Expansion beyond the graphics slot is one PCIe 4.0 x4 and one PCIe 3.0 x1. Video output is one HDMI at 4K 60 Hz plus DisplayPort over the USB4 Type-C port at up to 4K 120 Hz, and both need a CPU with integrated graphics. Onboard audio is a Realtek ALC897, a mainstream codec rather than the ALC4080 used on MSI’s TOMAHAWK and MPG boards. Socket AM5 means DDR5 only. The 5Gb LAN needs a 5GBASE-T switch to exceed gigabit.
Best For
✓ Gaming builds that also use a USB4 dock or external NVMe
✓ Ryzen 9000 systems with a PCIe 5.0 graphics card
✓ Users moving large captures or projects over 5Gb Ethernet

✓ Single-cable USB-C monitor or laptop-style docking setups
Key Features
USB4 at 40 Gbps with DisplayPort out
X870E requires USB4, and MSI delivers it as a rear Type-C port running at 40 Gbps that also carries DisplayPort at up to 4K 120 Hz. One cable can drive a monitor, connect an external NVMe enclosure and run a dock — the single biggest practical reason to choose X870E over B850.
Wi-Fi 7 plus Realtek 5Gb wired LAN
A Wi-Fi 7 module covers 2.4, 5 and 6 GHz with Bluetooth 5.4, and wired networking is a Realtek 8126 5Gb Ethernet controller rather than the 2.5GbE most gaming boards fit. Together they mean you are unlikely to be waiting on the network for anything.
Three M.2 slots, none reduced to x2
M.2_1 runs PCIe 5.0 x4 from the CPU, while M.2_2 and M.2_3 both run PCIe 4.0 x4 from the X870E chipset — the extra chipset lanes are why none of them is cut back to x2 as on many B-series boards. M.2_2 accepts longer 22110 drives.
Four DDR5 slots to 256 GB with EXPO
Four UDIMM sockets in dual channel take up to 256 GB with one-click AMD EXPO profiles and a rated ceiling of DDR5-8200 when overclocked. Starting with a two-module kit leaves a genuine upgrade path to 128 GB or 256 GB later.

Frequently Asked Questions
Is this an ATX or an ITX board?
It is full ATX, 304.8 x 243.84 mm, per MSI’s own specification. Some retailer listings incorrectly describe it as an ITX motherboard, which would be a very different size. Size your case for standard ATX.
What does X870E add over B850 on a gaming board?
USB4 at 40 Gbps is the headline, delivered here as a rear Type-C port that also carries DisplayPort at up to 4K 120 Hz. The chipset also provides more PCIe lanes, which is why all three M.2 slots on this board run at full x4 rather than one being cut to x2. If you never use a USB4 dock or external NVMe enclosure, a B850 board gives you the same PCIe 5.0 for less.
Is the audio codec a weak point?
It depends on how you listen. The ALC897 is a mainstream codec that is perfectly adequate for speakers and USB or wireless headsets, but it is a step below the ALC4080 on MSI’s TOMAHAWK and MPG boards. If you plug high-impedance headphones directly into the rear panel, consider one of those or a separate DAC.
What do I need to know before buying this board?
Full ATX at 304.8 x 243.84 mm, DDR5 memory only. Beyond the graphics card there is one PCIe 4.0 x4 and one PCIe 3.0 x1 slot. Both display outputs require a CPU with integrated graphics. The 5Gb LAN port only exceeds gigabit against a 5GBASE-T switch, router or NAS.
Singular Expert Insight
Most X870E boards are priced as workstation or flagship parts; the MAG line puts the chipset in reach of a normal gaming build. What you actually get for the X870E premium is USB4 and the extra chipset lanes that keep all three M.2 slots at x4 — both real, both easy to check against your own needs. What MSI has trimmed to make the price work is the audio codec, and that is the honest answer to why this costs less than a TOMAHAWK-tier X870E. If you use a headset over USB or wireless, you will never notice. Pair it with a PCIe 5.0 ready card from our
graphics cards range and a matched two-module
DDR5 memory kit, and put the Gen 5 SSD in M.2_1. Do check the reseller listing you compare against — several describe this board as ITX, which it is not.
Buyer's Guide
Buy it if
You want a gaming-oriented X870E board with USB4 at 40 Gbps, Wi-Fi 7 and 5Gb wired networking, PCIe 5.0 graphics and storage, and three full-bandwidth M.2 slots.
Skip it if
You never use USB4 or a fast wired network — B850 costs less for the same PCIe 5.0 — or you want premium onboard audio for wired headphones.
Also consider
The MSI PRO X870E-S EVO WIFI for the same chipset with professional styling, or the MSI MAG B850 TOMAHAWK WIFI if the ALC4080 codec matters more than USB4.
