This article covers ASUS AMD B450 搭載 AM4 マザーボード ROG STRIX B450-F GAMING 【 ATX 】【 第3世代 AMD Ryzen CPU に対応】.

Overview

The ASUS ROG STRIX B450-F GAMING is an ATX motherboard built around the AMD B450 chipset with an AM4 socket. It supports a wide range of AMD processors, including Ryzen 3rd Gen (3000 series), making it a cost-effective choice for mid-range gaming builds. Despite being a B450 board, it carries ROG hallmarks such as SupremeFX audio, Aura Sync RGB lighting, and premium VRM components. This board strikes an excellent balance between affordability and the high-end features enthusiasts expect from Asus’ Republic of Gamers line.

Product Info

Released in late 2018, the ROG STRIX B450-F GAMING sits in the mid-range tier of ASUS’s motherboard lineup. It uses a 6-phase digital VRM with high-quality chokes and capacitors, offering stable power delivery for CPUs up to around 105W TDP. The integrated SupremeFX S1220A codec delivers excellent on-board audio, while Aura Sync RGB headers allow lighting customization. Pricing typically ranges from ¥15,000 to ¥25,000 depending on availability and retailer. ASUS provides a 3-year warranty in most regions. The board lacks an integrated I/O shield (pre-mounted on newer versions) and does not support USB BIOS Flashback, so be cautious when upgrading to a newer CPU.

Best Use Cases

  1. Budget-to-mid-range gaming PC builder Pair this board with a Ryzen 5 2600/3600 and a mid-range GPU like the GTX 1660 or RTX 2060 for solid 1080p gaming. The B450 chipset saves money that can go toward a faster CPU or graphics card. 2. First-time PC builder With clear labeling, decent BIOS interface, and broad compatibility, this motherboard is a friendly choice for newcomers. Many units ship with updated BIOS, reducing the need for preliminary preparation. 3. Home server or secondary PC Using an APU such as the Ryzen 5 3400G, the board’s dual M.2 slots and SATA ports can be configured for storage-heavy workloads. Low power consumption and good reliability make it suitable for 24/7 operation. 4. RGB enthusiast Two RGB headers plus one addressable RGB header allow for impressive lighting setups with ASUS Aura Sync compatible fans, memory, and strips.

Things to Consider

  • PCIe 4.0 is not supported. If you need that bandwidth for a future GPU or NVMe SSD, consider B550 or X570. - The second M.2 slot shares bandwidth with SATA ports; check the manual for exact limitations. - No USB Type-C port on the rear I/O panel. - BIOS Flashback (USB-based recovery) is absent. If the board arrives with an outdated BIOS, you’ll need an older Ryzen CPU to boot and update. - The board has only two SATA ports, which may be limiting if you plan to use multiple SSDs/HDDs. Consider using M.2 drives for primary storage. - For extreme gaming or content creation with high-end CPUs (Ryzen 7 3700X and above), a more robust VRM design (e.g., X570 or B550 with better cooling) might be advisable. ## FAQ
    Q: Can I use a Ryzen 5 5600X on this motherboard? A: While the B450 chipset does support Ryzen 5000 series with a BIOS update, the ROG STRIX B450-F GAMING officially requires BIOS version 3820 or later. Check the ASUS support page for compatibility updates. Performance will be limited compared to B550/X570 due to PCIe 3.0 only. Q: What memory kit is recommended for this board? A: For plug-and-play, look for DDR4-3200 (CL16) kits that are listed in ASUS’s QVL. G.Skill Trident Z, Corsair Vengeance LPX, and Kingston HyperX are solid options. D.O.C.P. (Asus’s XMP loader) works reliably with most 3200MHz kits. Q: Is dual-GPU (CrossFire) performance any good? A: Two PCIe x16 slots operate in x8/x4 mode, so dual-GPU performance is not ideal for modern high-end cards. CrossFire is legacy technology, and most games no longer support it. A single powerful GPU is strongly recommended.
