BFG Technologies LS-680 680W power supply

680 W continuous ATX power supply

The BFG Tech LS-680 delivers 680 W of continuous DC power at 40 °C. It follows the ATX12V 2.2 and EPS12V 2.8 specifications and carries 80 PLUS certification with up to 85 % efficiency. A single 135 mm thermal-controlled fan adjusts speed to load. Four +12 V rails each provide up to 20 A, while the +3.3 V and +5 V rails supply 24 A and 30 A respectively.

Multi-GPU desktop builds needing native PCIe power

This unit suits builders running two graphics cards because it includes two 6-pin and two 6+2-pin PCIe connectors, removing the need for adapters. SLI certification and CrossFire readiness confirm multi-GPU support. Active PFC and full protection circuits (over-voltage, overload) add stability for high-draw systems. It is not for compact cases that cannot fit a standard ATX power supply, nor for builds that require more than four +12 V rails or higher per-rail current than 20 A.

Four +12 V rails at 20 A each

The four +12 V rails are each rated at 20 A, which determines how much current is available for CPU and graphics power phases. If your components demand more than 20 A on any single +12 V rail, this supply will not meet that requirement.
