Congratulations on the purchase of your
new CORSAIR Series High Performance
SFX power supply.
SF Series power supplies give you 80 PLUS Platinum eciency,
excellent electrical performance, and virtually silent operation in a SFX
form factor. With 105°C Japanese capacitors and Zero RPM fan mode,
they’re a great choice for high performance small form factor PC’s
where reliability and low noise are 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 SFX 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 SF 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.
