This article covers ASRock マザーボード X870 Livemixer WiFi AMD Ryzen 9000.

Overview

ASRock X870 Livemixer WiFi is a Socket AM5 ATX motherboard built on the AMD X870 chipset, designed for Ryzen 9000/8000/7000 series processors. It targets streamers, gamers, and content creators who need a balance of modern connectivity and sturdy power delivery. The 16+2+1 phase Dr.MOS VRM with 80A stages and large aluminum heatsinks ensures stable operation even under sustained load. Notable features include dual USB4 Type-C ports (40Gbps), WiFi 7 and Bluetooth 5.4, two PCIe 5.0 x4 M.2 slots (Blazing), plus two PCIe 4.0 x4 M.2 slots (Hyper). The rear I/O packs 25 USB ports in total, giving plenty of room for peripherals. ASRock also equips the board with 20K super-long-life capacitors (1000µF) for improved durability. Priced around ¥37,000–¥40,000, the X870 Livemixer sits at the affordable end of the X870 lineup while still offering premium features like USB4 and PCIe 5.0 support.

Compatibility Guide

CPU Socket: Socket AM5 – compatible with Ryzen 9000, 8000, and 7000 series (including Ryzen 5 7600 through Ryzen 9 9950X). A BIOS update may be needed for newer models. Memory: 4x DDR5 UDIMM slots, max 256GB, overclocking up to 8000+ MT/s with EXPO/XMP support. Form Factor: Standard ATX (305×244mm) – fits most mid-tower and full-tower cases. Power Supply: At least 750W recommended; 850W+ for high-end CPU/GPU combos. Storage: 2x M.2 PCIe 5.0 x4 + 2x M.2 PCIe 4.0 x4 + 2x SATA 6Gb/s. Quick-release latches simplify drive installation. Graphics: Single PCIe 5.0 x16 slot (no second x16 electrically x8/x4). Video outputs via HDMI 2.1 and USB4 Type-C (DP alt mode).

Product Info

The ASRock X870 Livemixer WiFi launched in 2025 as a mid-high-end offering. Its VRM design (16+2+1 phases, 80A Dr.MOS) comfortably handles 16-core Ryzen 9 CPUs. The board features two USB4 Type-C ports (40Gbps), one USB 5Gbps Type-C, and a total of 25 USB ports across rear and front headers. Networking includes a 5GbE Realtek LAN controller and MediaTek WiFi 7 (BE) with Bluetooth 5.4. Audio is handled by a 7.1-channel HD Codec. The M.2 heatsinks are aluminum with quick-release clips for tool-free SSD swapping. Warranty is typically 1 year (depending on retailer) with BIOS updates available on ASRock’s official website.

Best Use Cases

High-end gamers: Pair with an RTX 5090 or equivalent and a PCIe 5.0 NVMe SSD for ultra-fast load times and future-proof connectivity. Streamers: The abundant USB ports (25 total) easily handle cameras, microphones, capture cards, and lighting controllers. WiFi 7 provides low-latency wireless streaming options. Content creators: Four M.2 slots allow large RAID arrays for video projects. The VRM is strong enough to sustain prolonged rendering workloads with Ryzen 9 CPUs. Not recommended for: Budget builders on tight budgets (B650 boards offer similar features at lower cost) or anyone needing dual PCIe x16 slots for multi-GPU setups (the board has only one Gen5 slot). ## Alternatives
ASUS TUF GAMING X870-PLUS WIFI: Similar price and feature set. ASUS offers richer BIOS tuning options and a more established reputation for overclocking. Livemixer has more USB ports and the unique 20K capacitor claim. GIGABYTE X870 AORUS ELITE WIFI7: Also includes WiFi 7 and USB4, but with two PCIe 5.0 x16 slots (one runs at x4 electrically). Livemixer’s advantage is the dual USB4 Type-C ports and quick-release M.2 latches. Choose Livemixer if you prioritize USB connectivity and ease of M.2 installation; go with ASUS or Gigabyte if you need dual GPU support or prefer their BIOS ecosystems.

Things to Consider

BIOS update may be required for Ryzen 9000 series out of the box – check the sticker on the box or update via USB flashback (no CPU needed? verify board supports it – the evidence does not mention BIOS Flashback, so assume standard update procedure). PCIe 5.0 M.2 heat: While the board ships with decent heatsinks, close proximity of SSD and GPU can trap heat. Ensure good case airflow. No integrated GPU output: If your CPU lacks an iGPU, you must install a discrete graphics card even for basic display. 5GbE LAN: Less common than 2.5GbE; existing network infrastructure may not fully utilize the bandwidth. * Price vs. B850/E: If you don’t need USB4 or extra PCIe 5.0 lanes, a B850 board like ASRock B850 Livemixer (if exists) could save money. ## FAQ Q: Is the X870 Livemixer good for Ryzen 9 9950X? A: Yes, the 16+2+1 phase VRM with 80A stages can handle the 9950X even under all-core loads, though adequate cooling is recommended. Q: Can I use Thunderbolt 4 devices on the USB4 ports? A: USB4 is compatible with Thunderbolt 4 at the protocol level, but full Thunderbolt certification is not guaranteed. Many devices (displays, docks) work, but check compatibility lists. Q: How many M.2 SSDs can I install without losing SATA ports? A: All four M.2 slots are independent; no SATA port sharing is menti
