Featuring an ATX form factor, the Prime Ultra 550W Platinum Modular Power Supply from SeaSonic Electronics provides a single +12 V rail for stability and compatibility with current generation hardware. It also achieves 80 Plus Platinum certification, thanks its 92% efficiency at 50% system load.
It's built with multiple heavy-duty protection features and the modular design allows you to connect only the cables you need. Unused cables can be stored should you decide to upgrade your system down the road. With less cable clutter, there will be better airflow within the chassis for lower temperatures. A built-in 135mm fan operates silently, thanks to premium hybrid fan control, and provides additional heat dissipation.
