https://www.fjoddes.net/index.php/seasonic-core-tuf-gaming-alliance-psus-pictured/ Back in 2017, Seasonic introduced its CORE line of mainstream PSUs with 80 Plus Bronze efficiency. In 2019, the company wants to win more mainstream consumers, and hence unveiled a new line of CORE series PSUs boasting of 80 Plus Gold efficiency, partially/fully modular cabling, and ASUS TUF Gaming Alliance co-branding. The new 2019 CORE series come in various mid-range capacities starting from 450W, to 550W, 650W, leading up to 750W. The ones shown at Computex were 450W with partially-modular cabling and 650W with fully-modular cabling.
Seasonic is backing these PSUs with 7-year warranties.
Personally I find 7 years a bit low for the warranty.
