Antec GSK1000 ATX 3.1 Power Supply, 1000W, 80 Plus Gold, Full Modular, PCIe 5.1 12V-2x6, 10-Year Warranty

Your GPU is pulling more watts than your old PSU was designed for, and you're done guessing whether it'll hold under load. The GSK1000 delivers 1000W of ATX 3.1 power with a native PCIe 5.1 12V-2x6 connector — no daisy-chained adapters, no voltage drop. Full modular cabling means you only run what your case actually needs. 80 Plus Gold keeps the draw honest at the wall. Ten-year warranty covers the life of the build, not just the launch window.
