The Asus Pro WS Z890-Ace SE uses an LGA 1851 socket paired with the Z890 chipset and follows the standard ATX form factor, measuring 305 mm wide by 244 mm tall. It accommodates a single CPU and carries no integrated processor or integrated graphics. Overclocking is supported, and a clear-CMOS button makes BIOS resets straightforward, though the board does not feature dual BIOS. Wi-Fi and Bluetooth are absent, as is RGB lighting, keeping the build focused on wired, no-frills functionality. An HDMI 2.1 output is present on the rear panel, and the board is backed by a three-year warranty.
This board supports DDR5 memory across four slots arranged in a dual-channel configuration, with a maximum capacity of 192GB. Overclocked speeds can reach up to 9066 MHz, giving headroom for high-frequency kits. ECC memory is not supported.
The rear I/O panel offers a broad selection of USB connectivity, led by six USB 3.2 Gen 2 Type-A ports alongside one USB 3.2 Gen 2x2 Type-C port, one USB 4 40Gbps port, and one Thunderbolt 4 port; there are no USB 2.0, USB 3.2 Gen 1, USB 4 20Gbps, or Thunderbolt 3 ports. Network connectivity is handled by three RJ45 ports, and display output is provided solely through HDMI, with no DisplayPort, DVI, or VGA connectors present. eSATA and PS/2 ports are also absent from the panel.
Internal connectivity is well-provisioned, with eight SATA 3 connectors and four M.2 sockets available for storage, while SATA 2, U.2, and mSATA options are not present. USB expansion headers cover two USB 3.2 Gen 1 ports, two USB 3.0 ports, one USB 3.2 Gen 2x2 port, and four USB 2.0 ports, allowing front-panel and add-in connectivity to be built out flexibly. Cooling is supported through seven fan headers, and there is no TPM connector on the board.
The board provides three full-length PCIe slots in total: two PCIe 5.0 x16 slots and one PCIe 4.0 x16 slot, covering the needs of high-bandwidth add-in cards. There are no PCIe 3.0, PCIe 2.0, PCIe x8, PCIe x4, or PCIe x1 slots, and no legacy PCI slots are present.
The onboard audio supports a 7.1-channel layout and delivers a DAC signal-to-noise ratio of 120 dB, indicating a clean analog output stage. Two audio connectors are available on the rear panel, and an S/PDIF Out port is included for digital audio passthrough to external receivers or DACs.
The board supports RAID 0, RAID 1, and RAID 5 configurations, covering striping, mirroring, and parity-based redundancy respectively. RAID 10 (1+0) and RAID 0+1 are not supported.
