SeaSonic FOCUS-SPX-750

The SeaSonic FOCUS-SPX-750 is a compact SFX-format power supply delivering 750 watts, designed for small-form-factor gaming PCs, Mini-ITX systems, compact workstations, and cases where a standard ATX unit would consume too much space. Measuring 125 × 100 × 63.5 mm, the unit ships with an SFX-to-ATX bracket, enabling installation not only in SFX cases but also in select ATX cases to maximize cable management space and airflow. The unit carries 80 PLUS Platinum certification with a rated efficiency of 92% at 50% load. Fully modular cabling lets you connect only the rails you need, an essential feature in tight-fitting builds with limited component spacing. The +12V rail delivers up to 62 amps and 744 watts, making the SeaSonic FOCUS-SPX-750 well-suited for systems pairing powerful processors with discrete graphics cards within acceptable power budgets. Cooling comes via a 92 mm fan with Fluid Dynamic Bearing technology and SeaSonic's proprietary Hybrid Silent Fan Control, which operates in Fanless, Silent, and Cooling modes with fanless operation extending to approximately 30% load. The supply supports full input voltage range from 100–240V, carries an MTBF rating of 100,000 hours, and includes protections for OPP, OVP, UVP, OCP, OTP, and SCP.
