Gigabyte X870E AORUS MASTER X3D — flagship AM5 ATX for Ryzen X3D builds
AMD X870E · Socket AM5DDR5 up to 9000 MT/s (OC)10GbE + 5GbE · Wi-Fi 72x USB4 · 5x M.2
The Gigabyte X870E AORUS MASTER X3D (part number X870E A MASTER X) is a flagship ATX motherboard for AMD Socket AM5, built around the X870E chipset for Ryzen 9000, 8000 and 7000 processors and tuned especially for Ryzen X3D gaming CPUs.
An 18+2+2 twin digital VRM on an 8-layer, 2x-copper PCB feeds high-core-count chips, while four DDR5 slots support up to 256GB and overclocked kits up to 9000 MT/s. Storage is generous with five M.2 slots, two of them PCIe 5.0 x4 from the CPU.
Networking combines Realtek 10GbE and 5GbE ports with MediaTek Wi-Fi 7 (320 MHz) and Bluetooth 5.4, and the rear panel carries two USB4 Type-C ports with DisplayPort output, a USB 3.2 Gen 2x2 Type-C and seven 10 Gbps USB-A ports. The ALC1220 codec with an ESS ES9118 DAC handles audio.
Compatibility note: The second M.2 Gen5 slot (M2B_CPU) shares lanes with the USB4 controller — populating it drops both to x2. Filling the PCIEX8 slot runs the main graphics slot at x8, and the chipset PCIe x4 slot is disabled when M2D_SB is used. Wi-Fi 7 needs Windows 11 (no Windows 10 driver). Ryzen 8000 (Phoenix) CPUs lose the PCIEX8 slot and M2B_CPU.
Best For
✓ High-end Ryzen 7 9800X3D / Ryzen 9 X3D gaming rigs
✓ Creators needing fast multi-NVMe scratch storage
✓ 10GbE home-lab and NAS-connected workstations
✓ Enthusiast DDR5 memory overclocking
✓ Dual-GPU or GPU + capture card builds (x8/x8)
✓ Showcase builds with AORUS lighting and ARGB
Key Features
Robust 18+2+2 digital power
Twin digital VRM with 9+9 parallel phases, premium chokes and capacitors, direct-touch heatpipe and 12 W/mK thermal pads keep top Ryzen 9 chips at full boost.
Five M.2 slots with Gen5
Two PCIe 5.0 x4 M.2 slots from the CPU plus three PCIe 4.0 slots from the chipset, with M.2 Thermal Guard XL and tool-less EZ-Flex design; NVMe RAID 0/1/5/10.
Dual LAN + Wi-Fi 7
Realtek 10GbE and 5GbE ports plus MediaTek MT7927 Wi-Fi 7 with 320 MHz channels and Bluetooth 5.4 — room for NAS, workstation and gaming traffic at once.
USB4 and fast front USB-C
Two rear USB4 Type-C ports (40 Gbps, DisplayPort out) and an internal USB 3.2 Gen 2x2 header with up to 65W PD/QC 4+ fast charging for the case front panel.
Technical Specifications
Frequently Asked Questions
Singular Expert Insight
The Master X3D is a no-compromise AM5 board: dual Gen5 M.2, 10GbE and USB4 on one ATX PCB, with power delivery that will never limit a Ryzen 9. For a pure gaming build with one GPU and one or two SSDs, an X870 or B850 AORUS board delivers the same frame rates for much less. Pair it with fast DDR5 from our memory range.
✓ Buy it if you are building a flagship Ryzen X3D or Ryzen 9 system and want 10GbE, dual USB4 and five M.2 slots without add-in cards.
✕ Skip it if you only need one GPU, one SSD and 2.5GbE — a B850 board covers that at a fraction of the price.
→ Also consider the X870 AORUS ELITE or X870 AORUS INFINITY for a lower price with Wi-Fi 7, or B850 A ELITE boards for mainstream builds.
