The Asus Pro WS WRX90E-Sage SE is built around a single CPU socket and comes without an integrated CPU or integrated graphics, meaning a discrete processor and GPU are required. The board measures 330 mm in height and 305 mm in width, and it carries a three-year warranty. It supports easy overclocking and includes a convenient CMOS reset feature for straightforward BIOS recovery, while RGB lighting is also present. Notably, the board does not offer dual BIOS, and neither Wi-Fi nor Bluetooth are built in, so wireless connectivity would need to be added separately.
The board offers substantial memory capacity, supporting up to 2000GB of DDR5 RAM spread across eight slots running in eight channels for full parallel bandwidth utilization. ECC memory is supported, which allows the system to detect and correct memory errors — a meaningful consideration for data-sensitive workloads. Together, these specifications reflect a memory subsystem designed to handle large, sustained workloads without compromise.
The rear I/O panel provides a varied set of connectivity options, led by six USB 3.2 Gen 2 Type-A ports and a single USB 2.0 port for legacy peripherals. High-speed transfers are further covered by two USB 4 40Gbps ports and two Thunderbolt 4 ports, while USB Type-C is present on the board. Network connectivity is well-served with three RJ45 ports, and a VGA connector is included for basic display output. There are no DisplayPort, HDMI, DVI, eSATA, or PS/2 ports, and no USB 3.2 Gen 1, Gen 2 Type-C, Gen 2x2, USB 4 20Gbps, or Thunderbolt 3 ports are provided.
Internal connectivity is well-equipped, with four M.2 sockets and four SATA 3 connectors available for storage devices, while SATA 2 and mSATA connectors are absent. USB expansion is handled through four additional USB 2.0 headers and two USB 3.0 headers, allowing for extra front-panel or internal USB ports. Thermal management is supported by ten fan headers, giving substantial flexibility for cooling configurations. A TPM connector is also present for hardware-based security, and there are no U.2 sockets on this board.
Expansion on this board is handled exclusively through seven PCIe 5.0 x16 slots, providing significant room for multi-card configurations such as multiple GPUs or high-speed add-in cards. No PCIe 4.0, 3.0, 2.0, x8, x4, or x1 slots are present, nor are there any legacy PCI slots, meaning the expansion design is entirely consolidated around the PCIe 5.0 x16 interface.
The onboard audio supports 7.1-channel output and delivers a signal-to-noise ratio of 120 dB from its DAC, indicating a clean audio signal with minimal background noise. Two audio connectors are available on the board, and an S/PDIF Out port is included for digital audio output to compatible external devices.
The board supports a broad range of RAID configurations, including RAID 0, 1, 5, and 10 (1+0), covering common setups for performance, redundancy, and combinations of both. RAID 0+1 is not supported, which is the only mode absent from an otherwise comprehensive set of standard RAID options.
