Excellent efficiency makes this a great option if you use your PC every day, but it's quite expensive....

Over the course of a few years, the Seasonic X-650 could pay for itself, thanks to its high power efficiency. Compared with PSUs of just a few years ago, you’d be using up to 70W less for the same power compared with a five-year-old 650W PSU. Even...

The quality of the Seasonic X-Series 650W unit is stellar. Despite the new and untested base design, which we initially found to be rather odd, the use of premium components from companies such as Nippon Chemi-Con and Sanyo Denki increase the...

Notre premier modèle n'est autre que la Seasonic X-Series 650 watts. Une alimentation haut de gamme, à la certification 80 Plus Gold. Elle revêt une robe noire granitée, et intègre une grille au design alvéolé. Ses dimensions sont de 150 x 160 x 86...

Das Netzteil Seasonic X-650 mit der Modelnummer SS-650KM beweist eindrucksvoll das es heute möglich ist sparsame und gleichzeitig leise Netzteile zu bauen. Vollgestopft mit neuester Technologie wie DC to DC Technik, einer intelligenten...

Den nye X-serien er definitivt Seasonics store tilbakeslag etter en god stund med få lanseringer. Det interne designet er nytt, enheten er modulær hele veien, støynivået er lavt og samtlige linjer gjør det meget godt. Hadde...
