Asus Announces Trio of New ROG Zephyrus Gaming Laptops

Asus's ROG Zephyrus line of light, but powerful gaming laptops is gaining three new and influential members. In addition to the AMD-powered Zephyrus G GA502 (which we covered elsewhere in-depth), the company took the wraps off of the high-end ROG Zephyrus S GX502 and mid-range Zephyrus M GU502, both of which have Intel's new 9th Gen Core i7-9750H and 15-inch displays that operate at up to 240Hz. Asus also announced refreshes for two existing Zephyrus laptops, the 15-inch, 0.59-inch thin Zephyrus S GX531 and the 17-inch Zephyrus S GX701.

The Zephyrus S GX502 features either an Nvidia RTX 2060 or 2070 GPU that Asus says will be factory overclocked up to 1,540 MHz. Asus says that its advanced cooling system really helps with performance. The design uses six heat pipes and fans with ultrathin fins, which are strong enough to withstand high speeds. Users will be able to choose among Silent, Balanced and Turbo modes.

The very-similar Zephyrus M GU502 comes with RTX 2060 or GTX 1660 Ti graphics, but has the similar components and an identical design. The laptops have the same exact dimensions of 14.2 x 9.9 x 0.74 inches (36 x 25.2 x 1.89 cm), though the GX502 weighs 4.4 pounds (2 kg) while the GU520 is 0.22 pounds (0.1 kg) lighter.

Both Intel-powered Zephyrus laptops have 15.6-inch screens that are available in either 240Hz or 144Hz varieties with Nvidia G-Sync anti-tearing technology. The displays are also Pantone validated for color accuracy, because Asus knows that a number of creative professionals also use these laptops for video and photo editing.

Though they require proprietary power connectors to operate at full performance, both laptops have USB Type-C ports that they can use for charging or running at reduced performance, provided that you have a 65-watt adapter handy. The systems can also dispense up to 18 watts of power to fast-charge your phone or other mobile device.

The laptops will be available with up to 32GB of DDR4 RAM and SSDs that range from 256GB to 1TB. There will also be an option to get the laptop with dual SSDs in RAID 0.

Both the Zephyrus S GX502 and M GU502 will have RGB-backlit keyboards that provide 1.2 mm of travel. The vibrant colors are configurable via Asus's Aura Sync software.

The laptops will launch sometime in the next couple of months. Prices and exact configurations were not available at press time.
