This article covers ASRock マザーボード X870E Taichi Lite AMD Ryzen 9000 シリーズ CPU (Soket AM5) 対応 X870E チップセット EATX マザーボード 【国内正規代理店品】.

Overview

The ASRock X870E Taichi Lite is an EATX motherboard built around AMD's flagship X870E chipset, designed for Socket AM5 processors including the latest Ryzen 9000 series. It features a massive 27-phase 110A SPS power delivery system, ensuring rock-solid stability even under heavy multi-core loads. With dual USB4 Type-C ports, PCIe 5.0 support for both graphics and storage, and integrated Wi-Fi 7, this board is packed with cutting-edge connectivity.
Storage flexibility is a standout: one Blazing M.2 slot running at PCIe 5.0 x4, three Hyper M.2 slots at PCIe 4.0 x4, and six SATA3 ports give you up to ten drives total. Networking is handled by a Realtek 5G LAN controller and Wi-Fi 7 (802.11be), while audio duties are covered by a Realtek ALC4082 codec paired with an ESS SABRE9219 DAC and WIMA capacitors. This combination makes the Taichi Lite a compelling choice for enthusiasts who want flagship features without the full flagship price.

Compatibility Guide

  • CPU socket is AM5 only. Officially supports Ryzen 9000 series (Granite Ridge), but also works with Ryzen 7000 and 8000 series. A BIOS update may be required for newer CPU steppings; always check the ASRock CPU support list before purchase.
  • Memory: four DDR5 DIMM slots, dual-channel, up to 256GB capacity. Supports overclocked speeds up to DDR5-8200+ (OC) and both XMP and EXPO profiles. Use only DDR5 modules; DDR4 is not compatible.
  • Form factor: EATX (305mm x 267mm). This board will not fit in standard ATX or smaller cases. Ensure your case explicitly supports EATX motherboards and has enough clearance around the edges.
  • Power connectors: one 24-pin ATX main connector plus two 8-pin EPS12V CPU power connectors. For a Ryzen 9 9950X or similar high-TDP CPU, a quality 850W or higher PSU is recommended, especially if pairing with a powerful GPU.
  • PCIe slots: two PCIe 5.0 x16 slots (full x16 lanes). Supports AMD CrossFire multi-GPU configurations, though single-GPU setups are more common today.
  • Storage: one M.2 Key-M slot (PCIe 5.0 x4) with dedicated heatsink, three M.2 Key-M slots (PCIe 4.0 x4) with shared heatsink, and six SATA 6Gb/s ports. All M.2 slots support 2280 form factor.

Product Info

The ASRock X870E Taichi Lite launched in late 2024 as a slightly more affordable variant of the flagship Taichi series. It sits firmly in the high-end segment, offering nearly all the premium features of the standard Taichi (USB4, Wi-Fi 7, 5G LAN, premium audio) while trimming some cosmetic extras to reduce cost. The retail price hovers around ¥70,000 (approx. $470 USD) in Japan. Warranty is typically 1 year for domestic authorized products; check with your retailer for exact terms.

Best Use Cases

  • Enthusiasts building a top-tier Ryzen 9 workstation: The 27-phase VRM can handle 16-core CPUs at full load for hours, making it ideal for video editing, 3D rendering, or scientific computing. USB4 and 5G LAN accelerate large file transfers.
  • Future-proof gamers: With PCIe 5.0 support for both GPU and NVMe, this board is ready for next-generation graphics cards and SSDs. Wi-Fi 7 ensures your network won't be a bottleneck for years to come.
  • Storage hoarders: Ten drive connections (4 M.2 + 6 SATA) let you build a massive game library or media server without external enclosures. The M.2 heatsinks keep high-speed SSDs cool under sustained writes.
  • Who should skip this board: Budget-conscious builders, those planning a small-form-factor PC (Mini-ITX/MicroATX), or casual users who don't need overclocking or multiple high-speed drives will find better value in B650 or X670E boards.

Things to Consider

  • The EATX form factor is a major constraint. Many popular ATX cases cannot accommodate this board; double-check your case's motherboard support before buying. Cable management space may also be tighter.
  • At around ¥70,000, it's significantly more expensive than mid-range X870E boards from ASRock's own Pro series or competitors. However, the VRM quality, networking, and audio justify the premium for high-end builds.
  • USB4 video output only works with the CPU's integrated graphics. If you use a discrete GPU, the USB4 ports will not output video to a monitor. This is a common limitation on AM5 boards.
  • Achieving DDR5-8200+ OC speeds depends heavily on your CPU's memory controller quality. Always consult the official memory QVL for tested modules to avoid instability.

FAQ

Q: Can I use this motherboard with a Ryzen 7 7800X3D?
A: Yes, it works perfectly. The 7800X3D has a low TDP (120W), so the VRM will run cool and efficient. However, for pure gaming, you may not need all the features of X870E; a B650 board could save you money without sacrificing gaming performance.
Q: Do I need an extra heatsink for a PCIe 5.0 SSD?
A: The Blazing M.2 slot comes with a large integrated heatsink, which is usually sufficient for most PCIe 5.0 SS
