Seasonic Electronics S12III Series 650W 80 Plus Bronze ATX Power Supply

The Seasonic SSR-650GB3 is a power supply that delivers 650 watts of reliable output, making it a solid foundation for gaming towers, creative workstations, and everyday home or office PCs.

Its 80 Plus Bronze certification means the unit operates at 82 to 85 percent efficiency, converting more of the electricity it draws into usable power and giving off less heat in the process.

A 120 mm cooling fan adjusts its speed automatically. Under heavy loads it spins faster to move hot air out of the case, and during lighter tasks it slows down, keeping noise to a minimum.

All essential cables are fixed to the housing, so you will not be searching for the right leads during installation. Connectors for the motherboard, CPU, graphics card, SATA drives, and Molex peripherals are ready to plug in. A single +12 volt rail can deliver up to 648 watts, ensuring modern processors and GPUs receive consistent current without voltage drops.

Builders who want a solution that is straightforward and dependable will appreciate the no fuss setup and the five year manufacturer warranty, whether the goal is a first time build, an upgrade for a new graphics card, or a quiet office system that needs to run all day.
