Review CORSAIR Power Supply Pulled From One Pro

The Corsair SF400 Watt Gold Certified Fully Modular SFX Power Supply is a compact yet powerful solution for small form factor PC builds. This power supply delivers an impressive 400 watts of power and boasts 80 Plus Gold certification, ensuring high efficiency levels of up to 92%.

The SF400's fully modular design allows users to connect only the cables they need, reducing clutter and improving airflow within the case. Each cable is individually sleeved, adding a touch of sophistication to any build.

This power supply utilizes a single 12V rail, delivering a steady power output of up to 33.3A. It also features a silent 135mm magnetic levitation fan, which effectively cools the power supply while producing minimal noise. This fan only starts spinning when the power supply reaches 40 C (104 F), ensuring quiet operation under normal conditions.

The SF400 Gold also comes with a 7-year warranty, offering peace of mind to builders and enthusiasts. Its compact size (3.5 inches deep) and high power density make it an excellent choice for small form factor cases, while its gold certification and fully modular design make it a reliable and flexible power solution.

In summary, the Corsair SF400 Gold Certified Fully Modular SFX Power Supply is a high-performance and efficient power source for small form factor PC builds. Its fully modular design, quiet operation, and long warranty make it a smart investment for any builder seeking a reliable and versatile power solution.

Corsair SF400 is a compact, high-performance power supply unit (PSU) designed for small form factor (SFF) PC builds. Here are some pros and cons that might help you decide if this PSU is the right choice for you.

1. High Wattage Density: The SF400 offers an impressive 400 watts of power in a 140mm form factor, making it an excellent choice for power-hungry SFF systems.

2. Fully Modular: This PSU features fully modular cables, allowing you to use only the cables you need, reducing clutter and improving airflow in your case.

3. High Efficiency: The SF400 has an 80 Gold efficiency rating, meaning it converts up to 90% of the input power into output power, reducing energy waste and improving system performance.

4. Quiet Operation: The SF400 utilizes a Zero RPM fan mode, which means the fan doesn't spin at low loads, providing near-silent operation.

5. Compact Size: The SF400's small form factor makes it an ideal choice for small cases, allowing for better cable management and improved airflow.

1. Limited Cable Length: While the modular design is a pro, the cable lengths for some of the connectors might be too short for some cases, requiring extensions.

2. Expensive: Compared to some other PSUs in its wattage range, the SF400 can be more expensive.

3. Limited Overclocking: This PSU might not be the best choice for extreme overclocking due to its limited wattage and efficiency at high loads.

In conclusion, the Corsair SF400 is an excellent choice for those building SFF systems that require a high-performance, compact PSU. Its modular design, high efficiency, quiet operation, and impressive wattage density make it a top pick for many builders. However, its limited cable lengths, higher price point, and potential lack of overclocking capabilities are worth considering before making a purchase.

Recommendation: If you're building a small form factor PC and require a high-performance, compact PSU, the Corsair SF400 is an excellent choice. Its modular design, quiet operation, and high efficiency make it a top pick for many builders, despite its higher price point and potential limitations for extreme overclocking.
