The Fortron Dagger PRO 850W is a high-efficiency SFX form factor power supply designed for compact PC builds and small form factor systems. Manufactured by Fortron Source Corporation, a U.S.-based leader in power conversion solutions since 1983, this unit delivers 850W of reliable power with 80+ Gold certification, ensuring 90% efficiency and reduced energy consumption. The fully modular cable design allows builders to use only the cables they need, minimizing clutter and improving airflow in space-constrained builds.
This PSU features Active Power Factor Correction (PFC) for stable operation across 100-240V AC input, comprehensive protection systems including overcurrent, overvoltage, overheating, and short-circuit protection. The single 92mm ball-bearing fan with active cooling maintains optimal temperatures during extended use. With its compact dimensions (100mm W x 125mm D x 63.5mm H), the Dagger PRO 850W is ideal for Mini-ITX and SFF (Small Form Factor) gaming PCs, workstations, and compact server builds.
