1000W Fully Modular ATX Power Supply

The EVGA SuperNOVA 1000 G+ delivers 1000 W of continuous power through a single +12 V rail. It carries 80 PLUS Gold certification with typical efficiency of 90% at 115 VAC and 92% at 220 VAC to 240 VAC. A 135 mm fluid dynamic bearing fan provides quiet cooling. All cables are fully modular so you connect only what the build requires.

24-pin ATX plus eight 6+2-pin PCIe

The main 24-pin connector feeds the motherboard while eight 6+2-pin PCIe leads support multi-GPU configurations that are SLI and CrossFire ready. Twelve SATA power connectors handle large storage arrays. Full modularity removes unused cables from the chassis, improving airflow and easing cable routing in cases that accept a 180 mm deep unit.

Builders needing 1000 W Gold efficiency

This unit suits high-end desktop systems that demand clean, high-wattage delivery and long-term protection including OVP, UVP, OCP, OPP, SCP and OTP. A Power ON Self Tester is included for quick bench checks. It is not for compact ITX builds that cannot fit a 180 mm power supply, nor for users who need more than twelve SATA power ports or more than eight PCIe power leads.
