Review

The Corsair SF750 is a power-packed performer in the world of compact power supply units. Boasting a formidable 750 Watts output, this SFX PSU is designed to cater to both the high-performance requirements and spatial constraints of modern computing systems. Its attributes resonate well with enthusiasts who aspire to build compact yet powerful setups, ideal for mini-ITX builds. Let's delve into a detailed examination of this PSU's features, performance, and design, as informed by various reviews and our technical insights.

Design and Features

• Form Factor and Efficiency: The Corsair SF750 occupies a standard SFX form-factor chassis, making it a space-efficient option for compact systems. It is accredited with an 80 Plus Platinum efficiency rating, which is a testament to its cost-effective energy consumption and support for robust operations.
• Modular Design: A standout feature is its fully modular design, allowing users to connect only the cables they need, thus improving cable management and airflow within the system.
• Cable Configuration: It offers a generous assortment of connectors, including two EPS, four PCIe, and eight SATA connectors, catering to a wide range of high-performance components (TechPowerUp).
• Zero RPM Mode: The PSU is equipped with a Zero RPM Fan Mode which ensures noiseless operation during low to medium loads, enhancing user experience (PC Perspective).

Performance

The Corsair SF750 excels in performance metrics, maintaining excellent voltage regulation and AC ripple suppression even under full load. This makes it an ideal choice for those pushing their systems to the limits with power-intensive applications and gaming (PC Perspective). Impressively, its efficiency reaches up to 95% at 400-watt loads, which underscores its prowess in energy management (Tweak Reviews).

Heat management is proficiently handled by a 92mm fan with a rifle-bearing system. Despite being compact, it effectively dissipates heat, although it becomes slightly audible under intense load beyond 600 watts. The use of high-quality Japanese capacitors rated at 105°C further ensures reliability and longevity.

Pros and Cons

• Pros:
  • Impressive power density in a small package
  • 80 Plus Platinum efficiency rating
  • Fully modular with individually sleeved cables
  • Excellent build quality and reliability backed by a 7-year warranty
  • Includes SFX-to-ATX mounting bracket for flexible case compatibility (PC Perspective)
• Cons:
  • High cost compared to other SFX PSUs, attributed to its specialized niche
  • Short cable length, which may fall short in larger ATX cases (TechPowerUp)

Conclusion

In summary, the Corsair SF750 SFX Power Supply strikes an exceptional balance between performance, efficiency, and compactness. While it commands a premium price point, its robust feature set and design innovations justify the investment, particularly for users demanding high efficiency and flexibility in small form-factor builds. Whether it's powering a sleek mini powerhouse or supporting demanding graphics and processing tasks, the SF750 stands as a formidable contender in the PSU market.
