Been running the Corsair SF450 for about a year now. Originally paired it with an RX5700 and 3600X but upgraded to 3700X and 2080 Super about 6 months ago. Honestly didn't have a single issue. Crazy how good these SF itx units are from Corsair. Decided to upgrade to the SF600 just for some extra headroom after I got very close to msrp for the SF450.
