Corsair RMX Gold Fully Modular Power Supply Rm850x / 850 W
Fully modular, so you only connect the cables that your system needs. A 135mm ML fan utilizes a magnetic levitation bearing and custom engineered rotors for high performance, low noise, and superior reliability. EPS12V connector for compatibility with modern graphics cards and motherboards. 100% Industrial-grade, 105C rated Japanese capacitors ensure unwavering power and reliability. Supports Modern Standby sleep mode for extremely fast wake-from-sleep times and better low-load efficiency. Zero RPM fan mode for near-silent operation at low to medium loads. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power, reduces coil whine for quieter operation, and enables use of more energy efficient sleep states. Looks and appears new, unused, and in excellent condition. Unsure of actual usage.
