Power supply unit Seasonic CORE BC-750 ATX 3.1 750 W 20+4 pin ATX Black 80 PLUS Bronze

The Seasonic CORE BC-750 is a compact ATX 3.1 power supply delivering 750 W of continuous power for desktop PCs. Designed for everyday builders and gamers, it combines Seasonic engineering with an efficient 140 mm form factor, black scratch-resistant finish and active cooling via a 120 mm hydrodynamic bearing (HDB) fan. The unit meets ATX 3.1 requirements and includes modern GPU connectivity on higher wattage variants; the CORE BC-750 offers native compatibility with contemporary graphics cards while maintaining legacy connector support.

Advantages

The CORE BC-750 provides 80 PLUS Bronze efficiency to reduce wasted energy and heat, while Seasonic’s Smart and Silent Fan Control (S2FC) adapts fan speed to load and temperature for quiet yet effective cooling. Its compact 140 mm design fits a wide range of cases and the durable finish resists scratches. Built-in protections and industry certifications ensure reliable, standards-compliant operation for typical desktop use.
