Server Grade Design

ASUS Z170-WS couples innovative thinking with premium components to deliver industry-leading power efficiency.

ASUS introduce the industry‘s most durable 12K solid capacitors, and exclusive ASUS ProCool power connectors. Z170-WS is built to stay cool under pressure — and boosts performance, power efficiency and product longevity into extreme levels! In addition, Z170-WS is designed and tested for professional VGA, RAID and LAN cards, providing optimized graphics, storage and internet connecting speed for users. If you are looking for the extreme performance, look no further than Z170-WS.

12K Hours Capacitors

12K hour caps - Capacitors with World's Best Longevity

ASUS is the world's first motherboard manufacturer to introduce 12K solid capacitors, and X99-E WS is of course equipped. These Japanese-made capacitors are the most durable in the industry, able to endure up to 12K hours at 105 °C and 1.2M hours at 65 °C. This is far higher than the temperatures generated by everyday computing, so X99-E WS is built for endurance . Our 12k capacitors also boast lowered equivalent series resistance (ESR) for increased efficiency and minimized heat generation — improving overall performance!
