Alienware 16X Aurora AC16251 (P1CHK)

Product Description

The Alienware 16X Aurora AC16251 (P1CHK) is a Dell AI PC notebook built for demanding gaming and high-performance everyday use, combining an Intel Core Ultra 7 Series 2 255HX processor, Windows 11 Home, dedicated NVIDIA GeForce RTX 5060 graphics, integrated Intel Graphics, 32 GB of DDR5 memory, and a 1 TB NVMe solid-state drive in a 16-inch portable system. Its processor runs at 2.4 GHz and can reach up to 5.2 GHz, supported by 20 cores, including 8 performance cores and 12 efficient cores, 20 threads, and 30 MB of cache, while the Intel AI Boost neural processing unit provides up to 13 TOPS of NPU performance and contributes to a total processor performance of up to 33 TOPS.

The 16-inch WQXGA display gives the system a sharp 2560 x 1600 resolution with a 240 Hz refresh rate, 189 ppi pixel density, 500 cd/m² brightness, wide +85 and -85 degree horizontal and vertical viewing angles, and a 100% DCI-P3 colour gamut for rich visual output. The screen is designed for smooth and comfortable viewing with anti-glare treatment, Adaptive-Sync technology, Wide Viewing Angle support, Low Blue Light technology, Dell ComfortView Plus, a 0.13464 mm pixel pitch, a 5 ms overdrive response rate, and a 9 ms response rate without overdrive, helping gameplay, streaming, creative work, and general media feel fluid and visually detailed.

Graphics performance is delivered through a single discrete NVIDIA GeForce RTX 5060 GPU paired with 8 GB of GDDR7 SDRAM video memory, alongside Intel Graphics with up to 8 TOPS capability. NVIDIA G-SYNC and Advanced Optimus are included to support responsive gaming visuals, while the system is explicitly designed for gaming use. The display, graphics system, and Adaptive-Sync support work together to provide tear-free visual output, strong graphical fidelity, fast screen response, and smooth motion during intensive play.

Storage is handled by a 1 TB M.2 PCIe 4.0 NVMe SSD, giving the notebook fast access to games, applications, files, and media while reducing waiting times when loading large content. The 32 GB DDR5 SDRAM configuration uses two 16 GB SO-DIMM 262-pin modules running at 5600 MT/s, with non-ECC technology, a rated speed of 5600 MT/s, two memory slots in total, no empty memory slots, and support for up to 64 GB of RAM.

The Alienware 16X Aurora AC16251 is equipped for modern connectivity, offering Bluetooth, Wi-Fi standards 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.11ax, and 802.11be, as well as Gigabit Ethernet. Wireless connectivity is managed by a MediaTek MT7925 controller with dual-stream 2x2 and MU-MIMO support, while wired networking is handled by a Realtek RTL8111H Ethernet controller. Physical expansion includes two M.2 card slots with one available, along with HDMI, Thunderbolt 4 with DisplayPort 2.1 and Power Delivery, USB-C 3.2 Gen 2 with DisplayPort Alt Mode, two USB 3.2 Gen 1 ports, a headphone and microphone combination jack, and an RJ-45 LAN port.

Audio and video features are designed to support communication, streaming, gaming, and multimedia use. The notebook includes stereo speakers, a dual array microphone, a Realtek ALC3204 codec, and compliance with High Definition Audio standards. The integrated camera system includes a standard 1920 x 1080 RGB camera and a 640 x 360 infrared camera, with respective resolutions of 2.07 megapixels and 0.23 megapixels, CMOS sensor technology, 30 frames per second video capture, 1920 x 1080 and 640 x 360 video resolutions, an IR camera view of 86.6 degrees, and an RGB camera view of 80.2 degrees.

The input system includes a keyboard and touchpad, with RGB keyboard backlighting, a numeric keypad, one RGB lighting zone, and a Copilot key. Power is supplied by a 6-cell lithium-ion battery with a 96 Wh capacity and a battery weight of 351 g, while ExpressCharge support helps reduce downtime when charging. The included power adapter supports AC input from 100 to 240 V at 50 or 60 Hz and outputs 180 watts at 19.5 V and 9.23 A.

The chassis measures 35.698 cm wide, 26.543 cm deep, and 1.919 cm high, with a system weight of 2.66 kg. It is supplied with a power adapter and includes McAfee+ Premium for 1 year along with activation for a 30 day Microsoft 365 trial.
