This article covers Gigabyte B650 Gaming X AX AMD B650 ソケット AM5 ATX DDR5-SDRAM マザーボード.

Overview

The Gigabyte B650 Gaming X AX is an ATX motherboard built around AMD's B650 chipset, designed for the Socket AM5 platform. It supports DDR5 memory and PCIe 5.0, making it a solid foundation for Ryzen 7000, 8000, and 9000 series processors.
Positioned as a mid-range offering, this board strikes a balance between modern features and affordability. It includes onboard Wi-Fi 6E, 2.5GbE LAN, and a 12+2+1 phase VRM that can handle even Ryzen 9 CPUs under moderate loads. For gamers and enthusiasts who want the latest platform without paying a premium for X670/E, the B650 Gaming X AX is a compelling choice.
Gigabyte has also included practical touches like Q-Flash Plus for BIOS updates without a CPU, Smart Fan 6 for flexible fan control, and a PCIe 5.0 M.2 slot for ultra-fast SSDs. It's a well-rounded board that suits both first-time builders and experienced upgraders.

Compatibility Guide

This motherboard uses Socket AM5 and is compatible with AMD Ryzen 7000 (Raphael), 8000 (Phoenix), and 9000 (Granite Ridge) series CPUs. Memory support is limited to DDR5, with four DIMM slots supporting up to 192GB. Both XMP and EXPO profiles are supported for easy memory overclocking.
The ATX form factor fits most mid-tower and full-tower cases. The primary PCIe x16 slot (CPU-attached) runs at PCIe 5.0, while the secondary x16 slot (chipset-attached) runs at PCIe 4.0. There are two M.2 slots: one PCIe 5.0 x4 (CPU) and one PCIe 4.0 x4 (chipset). Four SATA III ports are available for additional storage.
Power delivery uses a 24-pin main connector plus an 8-pin and a 4-pin CPU power connector. The rear I/O includes USB 3.2 Gen2 Type-C, multiple USB 3.2 Gen1 ports, HDMI 2.1, DisplayPort 1.4, and antenna connectors for Wi-Fi.

Product Info

Released in late 2022, the Gigabyte B650 Gaming X AX sits in the mid-range segment of the AM5 motherboard lineup. It offers most of the key features of the platform—DDR5, PCIe 5.0, Wi-Fi 6E—at a lower price point than X670/E boards.
Key specifications include a Realtek ALC897 audio codec, Realtek 2.5GbE LAN, MediaTek MT7921 Wi-Fi 6E + Bluetooth 5.2, and a 12+2+1 phase VRM design. The board supports BIOS Flashback via Q-Flash Plus and includes RGB headers (both 3-pin ARGB and 4-pin RGB). The standard warranty is three years.

Best Use Cases

  1. Budget-Conscious Gamers Building an AM5 System
    Pair this board with a Ryzen 5 7600 or Ryzen 7 7800X3D for a high-performance gaming rig that doesn't break the bank. You get DDR5 speed and PCIe 5.0 for future GPUs and SSDs, while the B650 chipset keeps costs down. Not ideal for those who need multiple PCIe 5.0 M.2 slots or Thunderbolt 4.
  2. Users Planning a Long-Term Upgrade Path
    AMD has committed to supporting AM5 through at least 2027, so you can start with a Ryzen 7000 CPU now and upgrade to a future generation later. The board's VRM is capable enough for most Ryzen 9 SKUs, making it a future-proof foundation.
  3. Wireless-First Desktop Users
    With built-in Wi-Fi 6E and Bluetooth 5.2, you don't need to buy a separate wireless card. This is perfect for desks where running Ethernet is impractical, or for users who want a clean, cable-free setup.
  4. Who Should Skip This Board
  • Users who need three or more M.2 NVMe slots (only two available)
  • Enthusiasts requiring PCIe 5.0 on both M.2 slots (second slot is PCIe 4.0)
  • Anyone who prefers Intel platforms

Things to Consider

This board supports DDR5 only—there is no DDR4 compatibility. DDR5 memory is still more expensive than DDR4, so factor that into your total build cost. Additionally, out-of-the-box support for Ryzen 9000 series may require a BIOS update; use Q-Flash Plus to update without a CPU installed.
Compared to competitors like the ASUS TUF Gaming B650-PLUS WIFI or MSI MAG B650 TOMAHAWK WIFI, the Gigabyte board offers slightly fewer VRM phases and a more basic audio codec. However, it often comes in at a lower price, making it a better value for most mid-range builds.
Storage expansion is limited to two M.2 slots and four SATA ports. If you plan to use multiple high-speed NVMe drives, consider a board with more M.2 slots or use a PCIe adapter card.

FAQ

Q: Can I use a Ryzen 7 7800X3D with this motherboard?
A: Yes, the 12+2+1 phase VRM is more than sufficient for the 7800X3D's ~120W TDP. Even with PBO enabled, the board handles it without thermal or stability issues.
Q: Does this board support PCIe 5.0 graphics cards?
A: Yes, the primary PCIe x16 slot is PCIe 5.0-ready. You can install an RTX 40-series or RX 7000-series GPU and get full bandwidth.
Q: Can I update the BIOS without a CPU installed?
A: Yes, the Q-Flash Plus feature allows BIOS updates using only a power supply and a USB flash drive. No CPU or memory is required.
