Dell RT74M 90W AC Adapter, 4.5 mm Tip

Maintain steady power for compatible Dell devices with this 90 W AC adapter. Built for environments where uptime matters, it supports 120 V AC to 230 V AC input and uses a 4.5 mm tip for the correct device connection. That combination makes it a practical replacement or spare for IT teams standardizing on Dell hardware. For procurement teams, the value is straightforward: a purpose-built adapter that helps keep laptops and other supported systems in service without introducing compatibility guesswork. The 90 W output provides the headroom needed for everyday operation, while the broad input range supports deployment across common office power environments. This is the kind of accessory that earns its place in a support kit. It reduces downtime during break/fix events, simplifies spare-pool planning, and gives technicians a known-good replacement for field use. When a power adapter fails, the right replacement restores productivity quickly and avoids the cost of replacing the full device.
