Maingear, a maker of high-end gaming PCs, unveiled its most powerful laptop to date, the 18-inch Ultima 18 with desktop-like specs.
Developed in collaboration with Clevo, Ultima 18 aims to offer desktop-level specs in a gaming laptop — such as a 4K@200Hz G-Sync display, Intel Core Ultra 9 275HX processor, and up to an Nvidia GeForce RTX 5090 mobile GPU, all inside a chassis outfitted with metal lid and palm rest.
Designed for elite gamers and creators who demand top-tier performance without compromise, Ultima 18 is Maingear’s first laptop to support modern dual-channel DDR5 memory, PCIe Gen5 SSDs, dual Thunderbolt 5 ports, and Wi-Fi 7. Whether plugged in or on the move, this system delivers power, quiet efficiency, and immersive visuals for the most demanding workloads and graphics-rich games.
“Ultima 18 isn’t just a laptop, it’s a no-compromise desktop-class gaming rig that fits in a backpack,” said Wallace Santos, CEO of Maingear, in a statement. “We’ve engineered this notebook to handle the latest triple-A games, creative workloads, and AI-driven applications with headroom to spare. From the raw Maingear gaming system.”
4K gaming and creative power, fully unlocked

Featuring an 18.0-inch 4K (3840 x 2400) 200Hz display with 100% DCI-P3 color gamut, G-Sync support, and a 16:10 aspect ratio, ULTIMA 18 offers both vibrant color and lightning-fast refresh rates for fluid gameplay and pro-grade content creation. With a display response time of less than 7ms, every action-packed gaming scene is sharp, fast, and tear-free.
Full-throttle specs

Inside, Ultima 18 is powered by the new Intel Core Ultra 9 275HX processor (24 cores, 5.4GHz Turbo), paired with up to Nvidia RTX 5090 or 5080 mobile GPUs (up to 24GB GDDR7, 175W TGP). Combined with support for up to 192GB of DDR5 memory and four M.2 NVMe SSDs, including PCIe Gen5 from Samsung, Ultima 18 crushes load times, multitasks effortlessly, and keeps up with the most demanding creative and gaming workflows.
Like all Maingear systems, the Ultimate is free from any OS-choking bloatware. It is also equipped with Control Center, an application that allows users to quickly swap performance modes, customize per-key RGB lighting, adjust fan profiles, and assign macros. Nvidia Advanced Optimus seamlessly switches between integrated and discrete graphics, maximizing battery life without sacrificing performance.
With rear- and side-facing ports, gamers can plug in and expand with dual Thunderbolt 5 ports, HDMI
2.1, USB-A with Power Delivery-out, microSD reader, dual 2.5Gb LAN, and next-gen Wi-Fi 7. Whether
docked at a battle station or streaming wirelessly, Ultima 18 is future-ready with robust, high-speed
connectivity options, including the latest AR and VR headsets.
Built for the road, tuned to win

Even with its extreme performance capabilities, Ultima 18 keeps powered with a massive 98Wh battery, and is equipped with a compact, new 330W charger that is not only powerful but backpack-friendly. If a charge is needed in a pinch, the laptop also supports USB-C charging. The customizable per-key RGB keyboard with dedicated Copilot key, powerful 5-point audio system with two drivers, two tweeters and a subwoofer, powered by Sound Blaster Studio Pro 2, and a 5MP Windows Hello camera with IR round out a premium feature set tailored for serious gamers.
