SLI Performance 3D MarkFire Strike Extreme scope Testing Software:3D Mark (2013)Testing Configuration:MB:X99-E WS / CPU : Intel Core i7-5960X/DRAM: Samsung 21338GB x4 GPU: GTX780Ti / O.S.: Windows 8.1_64 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 ProCool Power Connector Beat Thermal Choke Dr. MOS MOSFET 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! ProCool Power Connector 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. Easy Maintenance 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, 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.
