ASUS ROG Strix B650E-I Gaming WiFi: mini-ITX AM5 motherboard explained

The ASUS ROG Strix B650E-I Gaming WiFi is a mini-ITX motherboard for AMD's AM5 platform. Mini-ITX boards measure about 17 x 17 cm, so they suit compact "small form factor" PC builds that still use current Ryzen processors, DDR5 memory and PCIe 5.0 storage. This page explains the main specs and what to confirm before building around it.

Socket and processor support

The AM5 socket supports AMD Ryzen Desktop 7000 Series processors, and ASUS says it is ready for Ryzen 8000 and 9000 Series as well. The listing notes that a BIOS update may be required for 8000 and 9000 Series chips. That usually means the board needs a newer firmware before it starts with a newer processor, so check the maker's compatibility list for the version your chip needs.

Power delivery and cooling

The board has 10+2 power stages fed by an 8-pin ProCool connector, with alloy chokes and durable capacitors. The VRM (voltage regulator module) turns the supply into the steady voltage the processor needs, and stronger power delivery typically helps multi-core chips hold their speeds under load. Thick heatsinks sit on the power stages, bonded with high-conductivity thermal pads, to help cooling stay quiet in a tight case.

Memory, storage and expansion

The board takes DDR5 memory. For storage there are two M.2 slots: a PCIe 5.0 slot with a large heatsink and a second PCIe 4.0 slot. PCIe 5.0 SSDs offer higher peak speeds than PCIe 4.0, but they also run hotter, which is why the heatsink matters. A PCIe 5.0 x16 SafeSlot, reinforced for heavy graphics cards, takes the graphics card.

Connectivity

• Networking: onboard WiFi 6E (802.11ax), Bluetooth 5.2 and Intel 2.5G Ethernet with ASUS LANGuard protection.
• USB: one USB 3.2 Gen 2x2 Type-C port, which is rated at up to 20Gbps, plus seven more USB ports.
• Video: HDMI 2.1 for using a processor with integrated graphics.

Audio and lighting

Audio comes from the ALC4080 codec with a Savitech SV3H712 amplifier, plus DTS Sound Unbound and Sonic Studio III software. For lighting there is one RGB header and one addressable Gen 2 header, controlled through ASUS Aura Sync. ASUS also lists AI Networking and Two-Way AI Noise Cancelation software features.

Size and weight

Mini-ITX is a small standard, so the listing's dimensions include the board with its attached parts. At about 1 lb, it is light, but mini-ITX builds need careful planning of the cooler, case and power supply.

Who it suits

It suits builders making compact gaming or workstation PCs who want a current AMD platform with fast storage, WiFi 6E and 2.5G Ethernet. If you plan a full-size tower with many expansion cards and drives, a larger board with more slots will probably suit you better.

What to check before you buy

• Case: confirm the case supports mini-ITX and has room for your cooler and graphics card.
• Cooler: check that the cooler fits AM5 and the clearance in your case.
• Memory: this board uses DDR5; DDR4 modules will not fit. Mini-ITX boards usually have just two memory slots.
• BIOS: if you use a Ryzen 8000 or 9000 Series chip, check whether an update is needed first.
• Power: the board needs an 8-pin processor connector from your power supply, and compact cases often need a small-format supply.

The short version

• A mini-ITX AM5 motherboard for Ryzen 7000, 8000 and 9000 Series (BIOS update may be required).
• 10+2 power stages, DDR5 and thick VRM heatsinks.
• One PCIe 5.0 M.2 slot and one PCIe 4.0 M.2 slot; PCIe 5.0 x16 SafeSlot.
• WiFi 6E, Bluetooth 5.2, 2.5G Ethernet and USB 3.2 Gen 2x2 Type-C.
• Aura Sync RGB with one RGB and one addressable Gen 2 header.
