Safety And Protection; Over-Voltage Protection (Ovp); Over-Current Protection (Ocp); Over-Temperature Protection (Otp) - Corsair HX1200 Manual

Congratulations on the purchase of your new Corsair
HX Series High Performance ATX power supply.
Corsair HX Series enthusiast power supplies are optimized for silence,
with a custom fan design and Zero RPM Fan Mode. 80 PLUS Platinum
rated efficiency ensures low-cost operation, and the fully modular
black cables allow for fast, neat builds. All Japanese 105°C capacitors
make it a great choice for high performance PCs where reliability
is essential.

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 HX 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.
