Corsair SF Series SF750, SF600, SF450 High Performance SFX Power Supply
Introduction
Congratulations on the purchase of your new CORSAIR Series High Performance SFX power supply. SF Series power supplies offer 80 PLUS Platinum efficiency, excellent electrical performance, and virtually silent operation in an SFX form factor. With 105°C Japanese capacitors and Zero RPM fan mode, they are an excellent choice for high-performance small form factor PCs where reliability and low noise are essential.
Safety and Protection Features
- Over-voltage protection (OVP): Shuts down the PSU if DC outputs exceed set levels (13.4V for +12V, 5.74V for +5V, 3.76V for 3.3V).
- Over-current protection (OCP): Ensures DC voltage rails remain within safe operating limits on the 3.3V, 5V, and 12V rails.
- Over-temperature protection (OTP): Shuts down the PSU when internal temperature reaches a set point, typically due to current overloading or fan failure.
- Short-circuit protection (SCP): Protects the unit and PC components by shutting down the PSU if any output impedance is less than 0.1 ohms, preventing shorts between rails or to ground.
Zero RPM Mode
Zero RPM mode allows the fan to remain off during low to medium loads. This technology uses internal PSU temperatures and power output levels to determine when active cooling is needed. The fan will activate automatically when higher cooling is required, ensuring efficient operation without unnecessary noise.

| SF600 | CP-9020182 | 100-240V | 10A-5A | 47-63Hz | 20A | 20A | 50A | 600W |
| -12V: 0.3A (3.6W) | +5Vsb: 2.5A (12.5W) |
Efficiency Curve: Similar to the SF750, the SF600 shows high efficiency across system loads, with 230VAC input yielding slightly better results.
Fan Noise Curve: Fan noise is minimal at lower power outputs and increases incrementally with higher power demands.
SF450
Dimensions: 125mm (W) x 63.5 mm (H) x 100mm (L)
Package Contents: (Same as SF750)
Power Table:
| Model | Part No. | AC Input Rating | Input Current | Frequency | Max Load (+3.3V) | Max Load (+5V) | Max Load (+12V) | Max Output |
|---|---|---|---|---|---|---|---|---|
| SF450 | CP-9020181 | 100-240V | 10A-5A | 47-63Hz | 15A | 20A | 37.5A | 450W |
| -12V: 0.3A (3.6W) | +5Vsb: 2.5A (12.5W) |
Efficiency Curve: The SF450 maintains high efficiency across its operating range, with 230VAC input showing a slight advantage.
Fan Noise Curve: Fan noise is minimal at lower power outputs and rises gradually as power output increases.
