SAFETY AND PROTECTION
INTRODUCTION
Congratulations on the purchase of your new CORSAIR TX-M Series ATX Power Supply!
CORSAIR TX-M Series semi modular power supplies deliver reliable 80 PLUS Gold efficient power to
your system.
Please be sure to only use the screws, cables, and other hardware included in the box. Use of third-party
hardware could result in damage to your power supply or your system and its components.
>
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)
OCP is featured 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.
