Description
ROG Zephyrus M GU502
POWER MEETS PORTABILITY. Within a lightweight and ultra-slim metal frame, the new ROG Zephyrus M fuses well-rounded performance with an exhilarating Windows 10 gaming experience. The latest 9th Gen Intel Core i7 CPU and NVIDIA® GeForce RTX™ 2060 GPU blaze through serious work and play, while up to 1TB of RAID 0 SSD storage provides ultra-fast load times across a vast library of games and apps. Immerse yourself in the 240Hz/3ms IPS-level display with super-narrow bezels, and go deeper with Hi-Res ESS Sabre audio.
SLEEK, STRONG, AND ULTRA-SLIM
The impressively lightweight form belies heavyweight power. At 18.9mm thin and 1.9kg, the Zephyrus M GU502 is 25% thinner and 45% lighter than typical 15’’ laptops. But it refuses to compromise between work and play, delivering dynamic performance and refined styling that’s truly the best of both worlds. Its sleek, reinforced metal chassis makes it resilient against everyday use and wear, while the subtle, soft-touch skin along the palm rest keeps it looking clean and professional for work anywhere.
STRENGTH WITHOUT THE WEIGHT
Forged from a special magnesium-aluminum alloy, the chassis is machined down to exceptional thinness while maintaining the strength and durability needed for everyday use.
SHAPED FOR STIFFNESS
Honeycomb reinforcements beneath the palm rest strengthen a highly trafficked area. The die-casted structure resists flexing while adding minimal material and weight.
SOFT-TOUCH SKIN
Soft-touch paint covers the palm rest, minimising smudges and fingerprints with a thin coating that helps sustain the sleek styling and subtle sparkle through to the end of the day.
SUBTLE YET STRIKING
The streamlined design stuns in its details. Contrasting brush finishes slice across the lid, dovetailing precisely with the strategic cut that frees airflow out the back. Subtle diamond cuts chamfer the exterior edges and dig deeper near the touchpad to let you open the laptop effortlessly with one finger. The ROG logo glows fire red, creating a striking visual contrast against the brushed black metal.
OVERACHIEVE WITH SPEED
Speed, power, and portability achieve a perfect balance in the well-rounded ROG Zephyrus M. Its ultra-slim frame houses a powerful 9th gen Intel® Core i7-9750H CPU with NVIDIA GeForce RTX™ 2060 graphics that can reach 1435MHz at 90W in Turbo mode. With up to 32GB of DDR4-2666 RAM and 1TB of speedy RAID 0 SSD storage, you can blaze through everyday work and multitasking faster, with lightning-fast load times even for heavy duty apps and large games. The ROG Zephyrus M slices through anything you throw at it.

NVIDIA GeForce RTX™ 20-series GPU/h5>
Fast, quiet performance. Real-time ray tracing and AI-enhanced graphics. And the mobility of the world’s thinnest and lightest designs. It’s everything you want. And it’s only in GeForce RTX gaming laptops.

NVIDIA Turing™ Architecture
This revolutionary architecture, combined with our all-new GeForce RTX™ platform, fuses together real-time ray tracing, artificial intelligence, and programmable shading. You've never created and enjoyed games like this before.

Real-Time Ray Tracing In Games
Ray tracing is the definitive solution for lifelike lighting, reflections, and shadows, offering a level of realism far beyond what’s possible using traditional rendering techniques. NVIDIA Turing™ is the first GPU capable of real-time ray tracing.

Performance
GeForce RTX™ gaming GPUs come loaded with next-generation GDDR6 memory, support for DirectX 12 features, and more. This is graphics reinvented.

DO MORE ON THE MOVE
Longer battery life makes true portability a reality in the versatile ROG Zephyrus M. Unplug and take full advantage of its easy-to-carry form factor with up to 8 hours of battery life* on a single charge. NVIDIA Optimus technology improves efficiency by intelligently turning off the discrete GPU when dedicated graphics power isn’t required, giving you more battery life for everyday work and productivity without slowing gaming performance.

TAP INTO PORTABLE TYPE-C POWER
USB Power Delivery supports secondary charging from portable power packs, so you don't have to fight for a socket when the battery gets low. Fast-charging support reverses the direction, using up to 3A to quickly rejuvenate smartphones and other devices. If you’re not loading the CPU or discrete GPU with intensive tasks, you can use a smaller adapter up to 65W that lightens your load on the road.

TRUE COLOUR AND SPEED ON DISPLAY
Outstanding colours and smooth gameplay unite in the vibrant 240Hz/3ms IPS-level display. The 15.6-inch panel is framed by slim 6.2-mm bezels, creating an 81% screen-to-body ratio that feels expansive. Combining full sRGB coverage with wide viewing angles makes the screen ideal for showcasing visual projects and media. The fast 240Hz refresh rate enables true high-FPS gameplay, while the 3ms grey-to-grey response time ensures crisper, clearer graphics even during intense, fast-paced matches.

HEAR ESS® SABRE AUDIO ROAR
Rarify your headphone experience by plugging in to the premium ESS® Sabre HiFi digital-to-analog converter (DAC) with Hi-Res Audio certification. The DAC delivers broader dynamic range with less distortion, giving you richer, clearer highs and lows, and you can immerse deeper with virtual 7.1-channel surround sound. Sans headset, the Zephyrus M’s Smart Amp-powered speakers let you to turn up the volume for more bass and dynamic range, without damaging the cones or compromising sound quality.

THE KEYS TO CUSTOMISATION
Type in style with a desktop-inspired keyboard made for gaming. Function keys are spaced and grouped for easy identification alongside dedicated hot keys that keep essential commands within easy reach. Full N-Key rollover ensures that simultaneous presses register correctly, increasing precision. Highlight key controls for different games and workflows with per-key RGB customisation*, and coordinate colours and visual effects across all of your compatible peripherals with Aura Sync.

INTELLIGENT COOLING IMPROVES YOUR EXPERIENCE
ROG's Intelligent Cooling philosophy mixes the right features and system settings to ensure the best experience for each chassis and components, no matter what you’re doing. The Zephyrus M's self-cleaning thermal module ejects dust to improve longevity, dual n-Blade fans spin 83 blades each to increase airflow, and ultra-thin fins expand the surface area for heat dissipation. ROG Armoury Crate software seamlessly switches between operating modes to optimise performance and acoustics for the task.

COMPREHENSIVE CONNECTIVITY
The ROG Zephyrus M has the connections you need for work and play. Alongside the USB 3.1 Gen 2 Type-C™ with DisplayPort™ 1.4 and Power Delivery, there’s a Type-A port for ultra-fast data transfers, and two USB 3.1 Gen 1 ports for must-have gear. HDMI 2.0 supports 4K UHD output at up to 60Hz for big-screen gaming and entertainment. Surf the web with 802.11ac Gigabit Wi-Fi, or connect to Gigabit Ethernet to get the lowest latency for serious multiplayer matches and LAN parties.
