INTRODUCTION
Congratulations on the purchase of your new CORSAIR RMx Series ATX Power Supply!
CORSAIR RMx Series fully modular power supplies deliver reliable 80 PLUS Gold efficient power to your system
combined with a high performance 140mm magnetic levitation (ML) fan.
> 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.
> Over-Current Protection (OCP)
The RMx 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.
