Zenbook 3 UX390

ASUS recommends Windows 11 Pro for business.

Unprecedented performance

Our engineers had an almost impossible task when choosing the components for ZenBook 3. Their goal was to create an ultra-thin laptop with unprecedented performance, and despite some tough challenges, they've succeeded. The result is an unbelievably powerful laptop, with 7th generation Intel® Core™ i7 processor, up to 16GB of 2133MHz LPDDR3 RAM, an ultra-fast up to 1TB PCIe® Gen 3 SSD, and the latest USB-C port with support for displays. So there's no need to worry about what you can or can't do with ZenBook 3 — it's practically unstoppable!

The incredibly powerful 7th-gen Intel Core i7 processor

ZenBook 3 brings you state-of the-art performance in an ultra-thin laptop. At the heart of ZenBook 3 is the powerful 7th generation Intel® Core™ i7 processor, delivering effortless performance for smooth multitasking. Designed without any compromise, the prestigious ZenBook 3 achieves a benchmark result that is at least 15% higher than its nearest rival, giving you all the performance you need — and more.

The coolest of cool

The problem with fast, ultra-thin laptops boils down to basic physics. To prevent the laptop enclosure itself getting hot, warm air inside needs to be expelled as quickly as possible to the outside world. With ZenBook 3's mighty Intel® Core™ i7 processor inside, our engineers had to invent a brand-new cooling system using state-of-the-art components such as a liquid-crystal-polymer fan impeller that's just 0.3mm thin, and a copper-alloy heat pipe with walls a mere 0.1mm thin. This innovative cooling system is an incredible 3mm thin, and gently routes the warm air through hidden vents in the hinge for efficient, serenely quiet cooling even under full load.

Less wait, more work

A high-performance solid-state disk (SSD) with a PCIe® 3.0 x4 interface gives ZenBook 3 the fastest storage available — more than twice as fast as the storage in a MacBook® — so you'll never be kept waiting for the operating system to boot or for applications to load. With no moving parts, SSDs are not only blindingly fast, but are reliable and totally silent.

The fastest memory, the best multitasking

In keeping with our search for the ultimate performance, for ZenBook 3 we chose the world's fastest LPDDR3 RAM, clocked at an amazing 2133MHz. Despite its speed, it uses very little power, helping to keep ZenBook 3 running for longer. And with up to 16GB RAM, your ZenBook 3 will handle multiple demanding tasks without skipping a beat.

Runs longer, charges faster

A laptop as beautiful, powerful and prestigious as ZenBook 3 deserves nothing less than all-day battery life, so to achieve its remarkable up to 9-hour autonomy we designed a special high-capacity 40Wh lithium-polymer battery, specially shaped to fit precisely into the impossibly thin profile. We also added fast-charge technology that allows you to charge it up to 60% capacity in just 49 minutes.

Batteries, redesigned

ZenBook 3 uses lithium-polymer batteries that last up to 700 charge cycles — three times the lifespan of standard lithium-ion cylinder batteries. The lithium-polymer batteries are precisely shaped in three different ways so they fit exactly in the available space. This clever engineering allows us to give ZenBook 3 a generous 40Wh battery capacity. Lithium-polymer batteries also retain up to 80% of their original capacity even after hundreds of charge cycles, so you don't have to worry about deteriorating battery performance.

Mobility without bounds

We live in a wireless world, and ZenBook 3 is fully equipped to give you the very best connections, everywhere. It features the latest power-efficient Bluetooth® 4.1, as well as dual-band 802.11ac Wi-Fi that's more reliable and three times faster than the previous-generation 802.11n. With integrated Miracast technology, you can easily stream music, movies, photos and games to any Miracast-compatible HDTV, or use a TV as an interactive second screen for big-screen multitasking. And with our exclusive software such as ASUS Remote Control and ASUS Share Link, you can create your own personal data cloud for fast, secure and convenient access to all your files, wherever they're stored — on your ZenBook 3, on your mobile devices, or in the cloud.

Ergonomic backlit keyboard

The world's best ultraportable laptop doesn't deserve a keyboard that's an afterthought, and with ZenBook 3 it's been engineered into the design from the start. The full-size backlit keyboard stretches from edge to edge, with just a 2.1mm bezel at each side, and has a key pitch (the distance between the centers of each key) of 19.8mm, the same as most desktop keyboards. And although the keyboard is incredibly slim — 28% thinner than the previous generation, in fact — there's still an impressive 0.8mm key travel, which is twice as much as some rivals!
