Features & Specifications


The most powerful SFX power supply in the market, perfect for the most power-dense small-form-factor PCs.


Utilizing PWM instead of the standard DC voltage control, the SF750 Platinum keeps noise low and delivers precise fan speed. The SF750 Platinum also utilizes a copper alloy heatsink, ensuring optimal thermal performance.


SF Platinum Series power supplies come equipped with premium, individually sleeved cables featuring a flexible paracord sleeve, ready to fit right into your new high-end PC. The individually sleeved cables also make routing and cable management a breeze, with a lower profile and improved flexibility.


SF Platinum Series power supplies include an SFX-to-ATX power supply adapter bracket enabling installation into any ATX compatible case.

CORSAIR offers a seven-year warranty on all SF Platinum Series power supplies, your guarantee of reliable operation that will last across several system builds. If you need help, CORSAIR customer service and tech support are always on hand.

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 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.
