A:Answer Hi Twan,
Great question! Aside from sporting an updated design, the 2021 RMx features:
• A Magnetic Levitation fan, providing optimal cooling at low noise levels
• Resonant LLC Topology with DC-to-DC Conversion, which provides clean, consistent power, reduces coil whine for quieter operation, and enables use of more energy efficient sleep states
Zero RPM Fan Mode, premium internal components (100% All Japanese 105°C Capacitors), and 80 Plus Gold certification are still consistent with our previous RMx PSUs! Feel free to let us know if you have any additional questions, we'd be happy to help: support.corsair.com
