Seasonic PRIME GX Spec and Price in France
PRIME GX is the gold entry to Seasonic's PRIME series: 90% efficiency at half load, fully modular cabling, a 170mm chassis that is shorter than either the PX or the TX, and the same twelve-year warranty. Wattages run 650W to 1300W, so it reaches high-end territory without the platinum or titanium price. It is the sensible pick if the warranty rather than the efficiency badge is what drew you to PRIME in the first place.
Prices include VAT.
