1. Features vary by model and specification. Availability varies by country and region.
2. ASUS secured the #1 spot for motherboard market share as of 2017, with DigiTimes reporting that the Taiwanese PC component giant owns 45% of the motherboard market.
3. The testing regimen includes the requirements of both military-grade standards and ASUS quality tests, and varies depending on the device. MIL-STD-810 testing is conducted on selected ASUS products only. These tests do not demonstrate fitness for military use, or adherence to US Department of Defense (DoD) contract requirements. Similarly, the test results should not be considered an indication or guarantee of future performance under the specified test conditions. Damage occurring under these test conditions – or any attempt to replicate them – would be considered accidental, and would not be covered by the standard ASUS warranty. Additional coverage is available with ASUS Premium Care.
4. Intel vPro is optional on selected models only. Availability varies by country and region.
5. ASUS Control Center is optional and availability varies according to country. Please check with your local ASUS retailer for details.
6. Certifications may vary by model and country.
