Seasonic 1kW ATX Power Supply, 100 → 240V ac Input, -15 V dc, 3.3 V dc, 5 V dc, 12 V dc, 5 VSB V dc Output

Seasonic’s engineers have implemented a new design feature, where instead of cables, the back panel and the PCB (Printed Circuit Board) are connected by a copper plate. This breakthrough solution not only lowers the chance of production errors during manual insertion but it also improves output power quality. Hybrid Silent fan Control: The industry’s first, Seasonic patented, advanced three-phased thermal control achieves optimal between silence and cooling. This Hybrid Silent Fan Control functions in three operational stages: Fanless Mode, Silent Mode, and Cooling Mode.

Reduced noise without increase in temperature,
Extended fan life due to the reduced number of fan rotations,
Optimized heat dissipation at all times,
Unsurpassed silent performance in Fanless Mode.
