Ultimate micro-ATX graphics power: Two-way PCIe Gen 3 at x16 speed X99-M WS is the first ASUS micro-ATX with PCIe slots able to accommodate up to two dual-slot graphics cards. The new motherboard supports both two-way NVIDIA® Geforce® SLI™ and AMD® CrossFireX™ configurations, making it an excellent choice for graphics professionals who depend on powerful graphics in areas such as design and modeling, medical research, plus processing-intensive simulation and rendering applications. In addition to graphics cards, extensive expandability offers ample room for RAID cards, PCI Express-based solid-state drives (SSDs), video-capture cards and many other popular components. Supreme Power Solutions ASUS X99-M 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-M 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-M 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-M 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-M 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-M 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.
