TAIPEI, Taiwan, January 7, 2026 — ASUS today unveiled Zenbook S14 (2026) UX5406, the next evolution of its premium ultrathin 14-inch Copilot+ laptop. This sophisticated new generation fuses elevated craftsmanship with next-level AI performance, powered by the latest Intel® Core™ Ultra Series 3 processor delivering up to 50 NPU TOPS. It’s encased in a durable and tactile all-metal body, with a Ceraluminum™ lid that features nature-inspired colors, exceptional strength, and effortlessly resists scratches and wear. 

Created for discerning, on-the-move professionals who demand both power and polish, Zenbook S14 unites aesthetics with intelligence. Its ultra-slim 1.1cm chassis — weighing a mere 1.2kg[i]  — showcases engineering mastery with up to a 28-watt CPU TDP thanks to its Thincredible vapor-chamber cooling system and dual whisper-quiet IceBlade fans. This AI-driven platform personalizes every interaction through adaptive performance, enhanced biometric privacy and AI assistance from Copilot. With a 3K ASUS Lumina OLED 120Hz 1100-nit[ii] display, a four-speaker sound system, WiFi 7, and a full suite of I/O ports, Zenbook S14 delivers immersive entertainment and seamless connectivity anywhere. 

Through advanced materials, precision cooling, and intelligent performance, Zenbook S14 redefines what’s possible for ultraportable computing. 

Precision performance, redefined 

At the core of Zenbook S14 lies the latest Intel Core Ultra Series 3 processor, which delivers 40% faster performance[iii], 10% lower power consumption[iv], and next-gen AI capabilities with its up to 50 TOPS NPU — 40% more TOPS than the previous generation. This cutting-edge architecture powers fluid multitasking, AI-enhanced creative tools, and responsive system optimization for every workflow.  

Peak performance of up to 28W CPU TDP is ensured by the uprated Thincredible thermal system, which now has a 37% larger 3D vapor chamber enabled by CNC milling. It also uses dual redesigned IceBlade fans to ensure efficient, quiet cooling under load, with enhanced airflow around the motherboard to optimize heat dissipation without noise intrusion. The system also has a whisper-quiet sub-25dB ambient cooling mode.  

This harmony of performance, efficiency, and endurance sets a new benchmark for ultrathin computing — effortlessly light yet uncompromising in power. 

Strong, stylish, intuitive 

After more than four years of study, ASUS engineers created Ceraluminum — a proprietary ceramic-aluminum composite that combines the refined touch of ceramic with the strength of aluminum. This exclusive material resists scratches and wear, stays lightweight, and retains a premium tactile finish that’s both elegant and durable. 

Zenbook S14’s CNC-machined chassis exemplifies purposeful craftsmanship. Weighing only 1.2kg, it balances portability with resilience, built to accompany users anywhere. Offered in Scandinavian White and the new Antrim Gray, its minimalist Nordic-inspired design draws from natural textures and tones — a study in sophistication that merges art with utility. 

The new EasyLift™ hinge is precisely engineered for optimal torque and angle, ensuring the display remains steady and wobble-free during use. A full-size ErgoSense keyboard with ergonomic dished keycaps offers a supremely comfortable typing experience, and the large touchpad has Smart Gesture support for effortless fingertip control.

Immersive and connected 

Zenbook S14’s 14-inch ASUS Lumina OLED display delivers a 3K resolution and a 120Hz refresh rate, achieving up to 1100-nit of peak brightness. It’s Pantone® Validated for accurate color rendering, and DisplayHDR™ True Black 1000 certified for outstanding HDR performance. The cinema-grade 100% DCI-P3 color gamut delivers vivid, natural colors. The result: breathtaking visuals with lifelike contrast, color accuracy, and motion clarity — perfect for creativity, streaming, or productivity.  

Its four-speaker Dolby Atmos® sound system — incorporating dual front-firing tweeters and dual woofers — delivers immersive audio depth and clarity, transforming everyday media into cinematic experiences.  

A comprehensive set of full-size I/O ports — including two Thunderbolt™ 4 USB-C®, USB 3.2 Gen 2 Type-A and HDMI®  2.1 TMDS — enables versatile on-the-go device connectivity, and WiFi 7 with ASUS WiFi Master Premium certification ensures the fastest, most reliable wireless connections. 

Quiet and secure 

Despite its incredible power, Zenbook S14 retains its remarkably slim 1.1cm profile. A CNC-cut geometric grille located above the keys also enhances airflow and keeps dust out. Ambient cooling delivers quiet operation with sub-25dB noise levels, while maintaining comfortable temperatures in the keyboard area.  

Privacy and protection are a top priority, with Zenbook S14 supporting Windows passkeys and incorporating Microsoft Pluton for robust hardware-to-cloud security. Windows Hello and the ASUS AiSense IR camera enable facial recognition, Adaptive Lock, and Adaptive Dimming for intelligent user awareness. Adaptive Lock locks the laptop when the user moves away, while Adaptive Dimming dims the screen when the users looks away, enhancing privacy. The new ASUS Voice Print technology recognizes the owner’s voice, ensuring secure, personalized interactions and precise voice-command accuracy.
