RMx and RMi Series PSU

RMx and RMi Series PSU

RMx and RMi series power supplies are built with premium components for great performance with very low noise. They’re 80 PLUS Gold certified and give users extremely tight voltage regulation with virtually silent operation. With all Japanese 105°C capacitors, they’re a great choice for high performance PCs where reliability is essential. The fully modular cable set makes installations and swaps easy. With the RMi’s Link compatibility, users can monitor and control aspects of their power supply.


Safety and protection

  • Over-voltage protection (OVP): Over-voltage protection for the 12V, 5V and 3.3V DC outputs is required to comply with the ATX specification. OVP shuts down the PSU in the event that the DC outputs exceed a set level, determined by the PSU manufacturer. The minimum voltage levels required for compliance are 13.4V for the +12V rail(s), 5.74V for the +5V rail and 3.76V for the 3.3V rail.
  • Over-current protection (OCP): The RMx and RMi Series features OCP on the 3.3V, 5V and 12V rails. OCP ensures that the output of the DC voltage rails remains within safe operating limits.
  • Over-temperature protection (OTP): OTP ensures that the PSU will shut down when the internal temperature reaches a set point. This is usually as a result of internal current overloading or a fan failure.
  • Short-circuit protection (SCP): A short-circuit is defined as any output impedance of less than 0.1 ohms. Amongst other things, SCP ensures that the PSU shuts down should the 3.3V, 5V and 12V rails short to any other rail, or to ground. It also ensures that no damage should occur to the unit, or your PC’s components in the event of a short.

The Corsair RMx and RMi Series PSU’s are available from the CMS Store.
