Seasonic one of the most well known and respected brands in power supplies has today introduced three Prime SnowSilent series PSU models. The series is marked by white main body, a chrome-finished steel fan grille, and a white impeller on said fan. The internal DC outputs and AC receptacles are contrasting black. There’s an intense design focus on keeping the noise output of these units low. The fan downright stays off below a load threshold, and only has a low noise output beyond that. The fans feature fluid-dynamic bearings to help low noise and longevity, to keep up with the series’ staggering 12-year product warranties.
