The Dell 240W Mini Tower Power Supply (model DHVJN) is a compact power unit designed specifically for Dell computer systems requiring 240 watts of continuous power output. This power supply features a mini tower form factor optimized for space-constrained desktop environments while maintaining reliable power delivery for standard computing applications. With dimensions typically around 150 mm width, 86 mm height, and 140 mm depth, the unit provides efficient power conversion with standard ATX compatibility for Dell proprietary motherboards.

The power supply delivers stable voltage regulation across multiple rails including +3.3 V, +5 V, and +12 V outputs, ensuring consistent performance for system components. It includes standard power connectors for motherboard (24-pin ATX), processor (4-pin CPU), and peripheral devices (SATA and Molex). The unit operates with an input voltage range of 100-240 V AC at 50-60 Hz, making it suitable for international use.

Built with quality components and featuring over-voltage protection, over-current protection, and short-circuit protection, this power supply maintains system stability under normal operating conditions. The cooling system incorporates a temperature-controlled 80 mm fan that provides adequate airflow while minimizing noise during typical usage. The black steel casing ensures durability and proper electromagnetic shielding.

This power supply is compatible with various Dell desktop models that require 240 W power capacity and features the standard mounting points for easy installation in compatible Dell chassis. The unit weighs approximately 900 g and is designed for reliable operation in office and home computing environments where consistent power delivery is essential for system performance.
