Seasonic Vertex GX-1000 1000W

An enthusiast-tier 1000W supply delivering 80 Plus Gold efficiency, full modularity, PCIe 5.0 12VHPWR, a 12-year warranty, and a hybrid silent fan mode. It's a strong fit for high-wattage single-GPU builds wanting Seasonic build quality and long coverage. Budget-focused 1000W shoppers may balk, since the street price carries a Seasonic premium over rivals.
