Corsair RM550x Fully Modular Power Supply
  • This Corsair RMx power supply Is absolutely silent when just using my Hackintosh for work stuff.
  • Absolutely no complaints. Modular design allows for cable control.
  • Large fan keeps things cool and runs very quiet.
  • Never had any problems in over a year of in continuous use.
  • The fan doesn't even spin under lower load. When you pull more watts the fan spins up but it is large and quiet.

  • This is a fully modular power supply.
  • The box has lots of fan power.
  • The power supply is very quiet, I have it installed on top of the desk.
  • This is super quiet, which probably has a lot to do with the Eco mode. Smart cooling is a really nice feature, this should come standard.
