It is also compatible with ATX PC cases but you need to buy an original SFX to ATX reduction.Key featuresPrecisely manufactured power supply with due reliability for the smallest computersHigh energy efficiency - 80 Plus Gold certificationSilent and powerful cooling with a 92mm fanFully modular cable setSuperior performanceThe 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 designThe 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
