Product details

The Alienware AC16251 gaming laptop offers essential performance in a sleek 16-inch design, equipped with an Intel Core Ultra 9 processor and NVIDIA GeForce RTX 5070 graphics. This model combines powerful gaming capabilities with practical portability in a durable indigo-colored plastic casing. The 16-inch WQXGA display operates at a 240 Hz refresh rate and 500 nits brightness, providing sharp QHD+ resolution that surpasses Full HD quality, while maintaining wide viewing angles thanks to IPS technology. Graphics performance is enhanced by 8 GB of GDDR7 video memory and over 4608 CUDA cores with improved ray tracing capabilities. The system memory includes 32 GB of RAM to support multitasking during intense gaming sessions, while 1000 GB of SSD storage enables quick boot times under 30 seconds and silent operation. The thermal management utilizes Cryo-Chamber cooling technology, directing airflow to critical components and maintaining performance during prolonged use. The laptop achieves up to 155 W total power consumption for demanding games without additional cooling accessories. The physical dimensions balance visibility and portability between traditional 15.6-inch and larger 17.3-inch formats. Connectivity includes standard ports without an optical drive and a QWERTZ keyboard layout. This device runs on the Windows 11 Home operating system and is designed for gaming applications where high refresh rates benefit fast-paced genres. The construction emphasizes durability with anodized aluminum lid and base plates integrated with the primary plastic casing.
