Unmatched memory expandability with 12 DIMM slots

ASUS Z11PA-U12 features 12 DIMM slots the most on any compact ATX motherboard giving it unmatched memory expandability. Together with support for dual double-deck GPUs, Z11PA-U12 makes an ideal platform for deep learning application development and education.

Dual OCuLink for efficient connections to NVMe devices

ASUS Z11PA-U12 features dual onboard OCuLink to provide efficient port-to-port connection with most OCuLink-supported NVMe devices, eliminating the need for PCIe transaction cards.

Connect up to 13 6Gb/s SATA storage devices

ASUS Z11PA-U12 comes with three mini-SAS HD connectors that support up to twelve SATA ports each for high-speed 6Gb/s connectivity with external devices and cleaner cable routing. Additionally, a 7-pin SATA port provides flexibility to connect an optical drive or extra SATA device.

Comprehensive IT infrastructure management solution

The latest ASMB9-iKVM module enables remote BIOS updates, fan control, standalone KVM with HTML 5 interface , video recording and BSOD capture. With out-of-band management, ASMB9-iKVM provides around-the-clock remote monitoring and diagnostics even if the server operating system is down or offline through a user-friendly, web-based graphical interface that works with all major browsers. ASUS Control Center (ACC) is a centralized and integrated IT management platform for monitoring and controlling ASUS commercial products, including servers, workstations and digital signage. ACC enables easier server management with functions such as BIOS updating without restarting the system, remote monitoring of multiple systems via mobile devices, and one-click software updates and dispatching.

Increased energy efficiency with ASUS ProCool Power Connectors

ASUS Z11PA-U12 comes with ASUS ProCool Power Connectors, which decrease power connector temperature for reduced power loss and increased cost savings.
