About the ASUS ROG Zephyrus S15 GX502G 15.6" FHD 144Hz Gaming Laptop, Intel Core i7-9750H, 16GB RAM, 256GB SSD + 1TB HDD, GeForce RTX

The ROG Zephyrus S15 GX502G is a 15.6-inch gaming laptop with a 144Hz FHD panel, a six-core Intel Core i7-9750H and an Nvidia RTX-class GPU. Its slim magnesium-alloy chassis and 240W power delivery make it more portable than most gaming laptops of its generation, and the 144Hz screen suits fast shooters. Reviewers rate the display and build highly but note that the fans get loud under load and that the CPU runs hot. It suits gamers who want desktop-class frame rates in a bag-friendly machine, not buyers who need long battery life or quiet operation.

Best forGamers who want high refresh rates on the moveStudents who game in a dorm and carry the laptop to classPlayers of fast shooters and esports titlesBuyers who value a slim metal chassis over battery life

Questions and answers

Is the 144Hz screen worth it for gaming?
Yes for fast shooters and esports titles, where the higher refresh rate makes motion clearer. For slower story games the benefit is smaller.
Does it overheat during long gaming sessions?
Reviewers report high CPU temperatures and some throttling under sustained load. Raising the rear of the laptop and using performance fan profiles helps.
Can I upgrade the RAM and storage?
Yes. The RAM is socketed and there is room for a second drive, so both can be upgraded after purchase.
How is it against the Zephyrus G14 or G15?
The G14 and G15 are newer and more efficient, with better battery life and newer CPUs. This S15 is heavier on power but still slim, and its 144Hz panel remains competitive.
Does it have a webcam?
No. There is no built-in camera, so you need an external one for video calls.
Is it good for video editing as well as gaming?
Yes. The six-core i7 and RTX-class graphics handle editing and rendering well, though the loud fans and warm chassis show up in long exports.
