Supreme Power Solutions
ASUS X99-E 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. X99-E WS is built to stay cool under pressure — and boosts performance, power efficiency and product longevity into extreme levels!
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 221°F (105°C) and 1.2M hours at 149°F (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!
ProCool Power Connectors
ASUS ProCool is the power connector reinvented! Compared with traditional power connectors, ProCool connectors ensure an exceptionally close and secure connection with the X99-E WS motherboard. This design is much stronger, and it also benefits power efficiency: the flush connection enables lower impedance and better heat dissipation, allowing cooler operating temperature.
Beat Thermal Choke
Higher Stability and Lower Power Loss with Beat Thermal Choke
ASUS Beat Thermal Chokes deliver great durability and up to 93% power efficiency under normal operation. A special fin design results in 3-5? lower choke temps for added stability, which is increased exponentially by use of highly conductive and efficient gold-treated coating. This translates into minimal-loss power delivery.
Dr. MOS MOSFET
Dr. MOS - The Do-More MOSFET
X99-E WS benefits from an integrated Driver-MOSFET (Dr. MOS) that both saves space and reduces operating temperatures. Compared with traditional MOSFET designs, the Dr. MOS high-side and low-side MOSFETs and built-in driver extend component lifespan and enhances power efficiency.
Q-Code Logger – One-Touch Status Checker
Q-code logger is your one-touch status checker 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 X99-E WS is meant for professional users who rely on non-stop operation, and for whom 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.
Drive Eight-Core CPU and DDR4 Performance Beyond all Expectations!
ASUS Exclusive OC Socket
The X99-E WS' CPU socket includes extra pins that connect proprietary circuitry to extra contacts found on Haswell-E's land grid array (LGA). When combined with our customized UEFI, this exclusive feature offers comprehensively-improved overclocking margins, especially under extreme liquid-nitrogen (LN2) overclocking. You'll enjoy better margins for memory overclocking, better comparative memory performance under the same frequencies, and better margins for CPU overclocking with minimal voltage drop — so you're able to push the latest processors and DDR4 memory beyond their limits! OC Socket is 100% compatible with the new Haswell-E LGA 2011-3 processors. Forget limits, break every performance barrier with OC Socket!
This is the first platform to support DDR4 memory, and it is capable of overclocking memory up to DDR4 3200+ MHz with all eight DIMMs fully loaded! ASUS-exclusive T-Topology circuit design plus patent-pending OC Socket unleash the full potential of DDR4 by minimizing crosstalk and signal reflections. Thanks to our expertise in motherboard layout design, signal timing issues are also greatly reduced, resulting in improved stability and overall performance. ASUS works with almost every DDR4 memory vendor to ensure the best compatibility – so you're assured reliable performance from your favorite brands.
