Supreme Power Solutions
Z97-WS couples innovative thinking with premium components to deliver industry-leading power efficiency
ASUS Z97-WS couples innovative thinking with premium components to deliver industry-leading power efficiency. Carefully engineered with Beat Thermal Chokes made of highly conductive and efficient gold-treated coating for minimal-loss power delivery and integrated Dr.MOS MOSFET that both saves space and reduces operating temperatures. For the latest workstation motherboard, ASUS introduce the industry's most durable 12K solid capacitors, and exclusive ASUS ProCool power connectors. Z97-WS is built to stay cool under pressure — and boosts performance, power efficiency and product longevity into extreme levels!

12K hour caps - Capacitors with World's Best Longevity
ASUS is the world's first motherboard manufacturer to introduce 12K solid capacitors, and Z97-WS is of course equipped. These Japanese-made capacitors are the most durable in the industry, able endure up to 12,000 hours' exposure to temperatures as high at 105°C. This is far higher than the temperatures generated by everyday computing, so Z97-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!

Hassle-free troubleshooting
Q-Code Logger – one-touch troubleshooter
Q-code logger is your one-touch troubleshooter that lets users easily check system status at any time. Plug a flash drive into adjacent USB port, press the motherboard's dedicated Q-Code logger button and all ASUS Q-Code event logs for the current live session will be copied to the drive even with the system off.

ASUS Dr. Power hassle-free power supply health monitoring
As the Z97-WS is meant for professional users who rely on non-stop operation, stable power delivery is critical. Real time power supply health detection helps prevent sudden system shutdown and provides hassle-free notifications should power delivery be insufficient. Additionally, LED messages on the board clearly indicate any relevant power issues in the event your system fails to boot.
