Built for gaining the competitive edge and achieving total domination, the Ultima 18 is MAINGEAR’s most powerful gaming laptop ever. Armed with the latest Intel® Core™ Ultra 9 290HX Plus processor, it’s your unfair advantage in every battle. Whether you’re chasing frames or high-fidelity immersion, Ultima 18 delivers both—without compromise.
With 24 blazing-fast CPU cores and support for up to 192GB of quad-slot dual-channel DDR5 memory, the Ultima 18 handles everything from esports to fully-modded open-worlds. Pair that with up to a RTX 5090 with 24GB of GDDR7, and you’re not just playing the game—you’re rewriting the rules.
An 18.0" 4K 240Hz G-SYNC display with 100% DCI-P3 color gives you exceptional color accuracy, cinematic visuals and competitive frame rates. Fast response times mean more shots connect, and more games won. Whether you’re sniping in 4K or crushing your lap times, your display keeps up without tearing.
With adjustable fan profiles and performance modes in the MAINGEAR Control Center, you choose whether you want unrestricted raw power or high-performance whisper-quiet operation. Go all-in on Performance Mode for max FPS or play balanced with Entertainment Mode for stealth gaming.
Whether you’re gaming or working on the go, NVIDIA Max-Q uses AI to optimize every aspect of your system, from dynamically managing power between components, to finding optimal balance in game settings, and even controlling temperatures to lower power drain. Paired with a 98WHr 8-cell battery, Ultima 18 brings desktop performance anywhere you go.
