Corsair SF450

Corsair is an American company renowned for its top-notch products. These include also trusted power supplies, especially those complying with the 80 Plus Gold certification, which guarantees up to 90% efficiency. Similarly to other modern Corsair power supplies, the Corsair RM650x is built with premium components and all Japanese capacitors ensuring rock-solid stability and sustained performance. The Japanese capacitors are rated at 105°C, so they offer high reliability even for the most demanding tasks.

Thanks to the SFX format, the power supply is designed for use in very small computers with an emphasis on performance. It is also compatible with ATX PC cases but you need to buy an original SFX to ATX reduction.

Key features

  • Precisely manufactured power supply with due reliability for the smallest computers
  • High energy efficiency - 80 Plus Gold certification
  • Silent and powerful cooling with a 92mm fan
  • Fully modular cable set

Superior performance

The efficient SF series design ensures minimum excess heat and thanks to the Zero RPM fan mode, the fan does not need to turn on at low and medium loads. The specially designed 92mm fan has an optimized blade profile for low-turbulence airflow and near-silent operation even at full speed.  Naturally, the fan speed is dynamically adjusted based on the power supply load and temperature.

Modular design

The flat cables are fully modular, so you can use only the ones you need. This saves space in the computer case and thus helps to maximize airflow and lower the temperature. The Corsair RM650x brings the term "modular power supply" to perfection, as the user can even adjust the +12V rail configuration – you can toggle between single-rail and multi-rail power supply mode.

Maximum output rating:
+3.3V / 15A
+5V / 20A
+12V / 37.5A
-12V / 0.3A
+5Vb / 2.5A
