Power for mainstream and gaming builds

This Seasonic S12III Bronze Series unit delivers 550 W of continuous power for a mainstream system or gaming rig. It meets the 80 PLUS Bronze standard with 82% efficiency at 20% and 100% load and 85% at 50% load. A single +12 V rail simplifies power distribution to the CPU and graphics card. Japanese capacitors rated at 105 °C support long-term reliability.

Fixed cables and a 140 mm depth

The non-modular design provides every cable needed for a standard PC, including a 20+4-pin main connector, two 6+2-pin PCI-Express connectors and six SATA power connectors. At 140 mm long the unit fits most ATX cases, but verify clearance before ordering. The 120 mm sleeve bearing fan is regulated by Seasonic S2FC fan control to balance noise and cooling.

550 W on a single +12 V rail

The single +12 V rail design delivers the full 550 W to CPU and GPU without multi-rail balancing. Active PFC accepts 110-240 V input at 50/60 Hz for worldwide use. Protection circuits include OPP, OVP, UVP and SCP to safeguard components. MTBF exceeds 100,000 hours.
