What customers say
The Corsair SF750 Platinum is highly regarded in the Small Form Factor community for its exceptional power delivery within a compact SFX design. Customers consistently praise its outstanding build quality and reliable, stable performance, even when systems are heavily loaded. The Platinum efficiency rating is valued for reducing heat and energy use inside tight enclosures. A major benefit is the fully modular cabling, which greatly simplifies management and improves airflow. Furthermore, its quiet operation, often utilizing a Zero RPM fan mode, contributes to a silent computing experience. Despite a premium cost, users feel the unparalleled performance and reliability for its size make the investment worthwhile, cementing its status as a top choice for compact, high-performance builds.
Know before you buy
Yes, the SF750 is an SFX-sized power supply, but it includes an ATX adapter bracket in the box. This allows you to mount it securely in standard ATX cases if you prefer a more compact power unit.
The SF750 is designed for low-noise operation, featuring a 120mm fan that stays quiet under moderate loads. Its 80 Plus Platinum efficiency also helps reduce heat, meaning the fan doesn't have to work as hard to keep the unit cool.
These cables are specifically tailored for Small Form Factor (SFF) builds, meaning they are shorter than standard cables to reduce clutter. If you are using a mid-tower or full-tower case, you may find the cables too short to route comfortably.
With 750 watts of power and multiple 6+2 pin PCI Express connectors, the SF750 is capable of supporting most modern high-performance GPUs. Always check your specific graphics card's power requirements to ensure it falls within the 750W limit.
Being fully modular means every cable can be detached from the power supply unit. This is a significant advantage in compact builds, as you only need to plug in the specific cables your components require, which drastically improves airflow and makes cable management much easier.
