Introduction and Features
750W of Platinum power in a small SFX package.
The latest entry in the power density race to cross our test bench is the SF750 power supply from Corsair. The SF750 is housed in a standard SFX small form-factor chassis and can deliver up to 750W of combined DC power. Note we said standard SFX chassis – not an extended or lengthened version.
SFX SFX-L ATX
As you can see in the photo above there is quite a difference in size between the three form-factors.
In addition to their compact size all three Corsair SFX Platinum Series SFX power supplies feature fully modular cables and are 80 Plus Platinum certified for high efficiency. They feature a Zero RPM Fan Mode for silent operation at low to medium power and come backed by a 7-year warranty. And an SFX-to-ATX mounting bracket is included. We will be taking a detailed look at the Corsair SF750 Platinum power supply in this review.

Here is what Corsair has to say about their new SF Platinum Series:
The SF Platinum Series comes in three models: 450W, 600W and 750W. “CORSAIR SF Platinum Series SFX (small form factor) power supplies are fully modular and optimized for silence and high efficiency. Zero RPM Fan Mode means that the fan doesn’t even spin until the power supply is under heavy load, and the fan is custom-designed for low noise operation even at high loads.
And unlike other SFX power supplies, the SF Platinum Series features a 92mm fan, as opposed to an 80mm fan. This allows the fan to move the same volume of air at a lower RPM.
The 80 Plus Platinum rated efficiency saves money on your power bill, and the flat black cables are fully modular, so you can enjoy fast, neat builds. And, like all CORSAIR power supplies, SF Platinum Series is built with high-quality components, such as 105°C rated Japanese capacitors, and is guaranteed to deliver clean, stable, continuous power.”
