Expert Features
- Ryzen AM5 Firepower : Built for AMD Ryzen 9000, 8000, and 7000 Series desktop processors, giving gamers a serious upgrade path across multiple AM5 generations without rebuilding the whole kingdom.
- 14 + 2 + 1 Power Stages : The VRM uses 14 VCORE, 2 SoC, and 1 miscellaneous power stage, with every stage rated for up to 80A, backed by dual 8-pin CPU connectors, ProCool construction, alloy chokes, and durable capacitors.
- DDR5 Up To 8000+ MT/s OC : Four DIMM slots support up to 256GB DDR5, dual-channel operation, AMD EXPO, AEMP, and both ECC and non-ECC unbuffered memory for flexible high-performance builds.
- PCIe 5.0 Graphics Support : Ryzen 9000 and 7000 processors unlock a full PCIe 5.0 x16 graphics slot; Ryzen 8000 processors use the same slot in PCIe 4.0 x8 or x4 mode depending on the installed CPU.
- Four-M.2 Storage Arsenal : One CPU-connected slot supports PCIe 5.0 x4 with Ryzen 9000 or 7000 CPUs, while three additional PCIe 4.0 M.2 positions give high-speed SSD builders proper storage freedom.
- WiFi 7 Plus 2.5GbE : Get tri-band 2.4GHz, 5GHz, and 6GHz WiFi 7, up to 160MHz channels, Bluetooth 5.4, and Intel 2.5Gb Ethernet for low-latency gaming, streaming, and fast local transfers.
- WiFi Compatibility Explained : Full WiFi 7 functionality requires Windows 11 version 24H2 or later; older Windows 11 releases operate at WiFi 6E capability, while Windows 10 supports WiFi 6 only.
- USB-C 20Gbps Connectivity : The rear USB-C 20Gbps port handles seriously fast external storage, while additional 10Gbps, 5Gbps, and USB 2.0 connections support a full gaming-peripheral invasion.
- SupremeFX Gaming Audio : The Realtek ALC1220P codec, Savitech SV3H712 amplifier, 120dB playback SNR, 113dB recording SNR, optical S/PDIF, premium capacitors, and Dolby Atmos support deliver richer positional audio and cleaner headset output.
- AI Cache Boost : With a compatible Ryzen 9000 processor, ASUS AI Cache Boost optimizes CPU cache and memory pathways for supported local AI and large-language-model workloads.
- Heavy-Duty Cooling : Large VRM heatsinks, high-conductivity thermal pads, M.2 cooling across three top-side SSD positions, an AIO pump header, and multiple PWM/DC fan headers keep heat under control when the build starts breathing fire.
- Builder-Friendly Q-Design : PCIe Slot Q-Release, M.2 Q-Release, M.2 Q-Latch, Q-DIMM, Q-Antenna, Q-Dashboard, Q-LED, BIOS FlashBack, Clear CMOS, and a pre-mounted I/O shield reduce assembly drama and troubleshooting pain.
- White Micro-ATX Statement Build : The 24.4 × 24.4cm micro-ATX layout combines a distinctive white PCB with ROG design language, Aura Sync, and three Addressable Gen 2 RGB headers for compact white gaming systems that do not look generic.
