The FORTRESS Series features 80Plus Platinum rating up to 94% efficiency. The rating translates into cooler temperatures across the board which provided the opportunity to use a silent 135mm fan. It also comes equipped with a single 12V rail that outputs up to 62.5A and comes with four 6+2 PCI-e connectors on the 750W model. Coupled with the 80Plus Platinum Certification, your components will be getting clean and efficient power at all times.
