Description
Endlessly expandable: Your tower can support up to 225W full size graphics cards and up to four storage devices. Enjoy plenty of storage with capacity for three 3.5″ HDD bays or 2.5″ NB drives plus one internal optical drive. Four tool-less PCle slots let you add in sound cards, graphics cards and more.Your command center: Connect all your devices in a snap with 11 total USB ports, including two USB Type-C ports – one now available in front – plus an additional three front-facing USB-A ports.
Strong and silent: Even at full load, we’ve tested the tower to ensure that it stays as quiet as a whisper. With thermally controlled fans, the system is designed and built to meet Dell’s rigorous acoustic limits, so system noise is never a distraction.
Keep your cool: An optimized airflow path uses side vents to draw cool air across graphics cards and CPU, while a separate airflow path cools the power supply unit. Rigorous, proprietary testing ensures that all system components are kept cool, even under the most intensive loads.
Award-winning audio: The XPS Tower is engineered for premium high fidelity sound quality and tested to ensure crackles and pops are eliminated. GRAMMY Award-winning Waves MaxxAudio® technology with MaxxSense adapts to the environment, making external speakers sound fuller, louder and clearer.
Two powerful 5dBi antennas and 2×2 MIMO enhance wireless transmission to deliver broader wireless coverage with stronger signal intensity.
