SF Series power supplies bring legendary Corsair performance and reliability to the SFX small form factor standard. They have the features found in full-size high performance power supplies, with super-efficient 80 PLUS Gold certification, superior voltage regulation, Zero RPM mode for virtually silent operation, and 105°C All Japanese capacitors for better reliability.
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.
The Corsair SF Series PSU’s are available through the CMS Store.
