Today we take a look at one of the newest power supplies from market leader Corsair – their new SF750 SFX Platinum. Previously the SF Platinum series shipped in only 450W and 650W capacities, so this new high model will appeal to the hard core enthusiast user looking for a high wattage small form factor supply. This supply also features a larger 92mm fan, rather than 80mm and it has a ‘Zero RPM Fan mode' to reduce noise output under lower load situations.

Corsair are keen to point out that lowering noise is one of their key focus points with the SF750. Many small form factor power supplies are equipped with a tiny 80mm fan, which are typically known to generate a lot of noise. By moving to a 90mm fan, they are able to spin the fan slower while producing good levels of airflow – all while reducing noise emissions. They also state that due to careful component selection that coil whine will not be a problem. I will test this out later.

Additionally, as we would expect in this price point, the SF750 is a fully modular power supply featuring very high Platinum efficiency certification. This is a standard sized SFX chassis too – its not one of the extended length versions we see from time to time from other companies.
