EVGA SuperNOVA 850G XC ATX3.0 & PCIE 5, 80 Plus Gold Certified 850W, 12VHPWR, Fully Modular, ECO MODE with FDB Fan, 100% Japanese Capacitors, Compact 150mm Size, Power Supply 520-5G-0850-K1

Part Number: 520-5G-0850-K1
Introducing the EVGA SuperNOVA 850G XC - The first ATX 3.0 compliant and PCIe 5.0-ready power supply from EVGA. Featuring a half-bridge LLC resonant controller, DC-DC converter, APFC, and 100% Japanese Capacitors, this power supply is extremely stable with low ripple and noise, and 80 Plus Gold-rated for efficiency. The SuperNOVA 850G XC includes a native 12VHPWR cable capable of delivering up to 600W output, while supporting up to 200% Total Power Excursion and 300% GPU Power Excursion for PCIe 5.0 graphics cards. An ultra-quiet PWM-controlled FDB fan runs completely silent at medium-low loads and temperatures thanks to EVGA ECO Mode. With a full-suite of protections and EVGA's 3-Year limited warranty, the EVGA SuperNOVA 850G XC gives you everything you need for a modern gaming system.
