The FOCUS PLUS Gold 550W power supply from Seasonic is a fully modular power supply with the 80 PLUS Gold rating. For cooling it has a quiet 120mm fan, which can turn off entirely at lower power loads (in what Seasonic calls "Hybrid Mode") to further reduce noise. Together with its 10-year manufacturer warranty, this unit provides reliable, quiet operation for computers with moderate power requirements.
William George (Go-To-Market (GTM) Manager) Says:
This is a great PSU for most systems with a single CPU and GPU (video card)... though some combinations of high wattage parts - like a Threadripper CPU, Titan-series GPU, and multiple hard drives - might warrant moving up to the next larger power supply.
