The Cooling Master V850 Sfx is a high-performance power supply unit designed for gamers and PC enthusiasts. Its compact size and robust features make it a popular choice for small form factor builds. In this review, we explore its performance under load and stress conditions to determine its reliability and efficiency.
Overview of Cooling Master V850 Sfx
The V850 Sfx offers 850 watts of power, supporting the latest hardware components. Its fully modular design allows for easy cable management, improving airflow and aesthetics. The unit is 80 Plus Gold certified, promising high energy efficiency and reduced heat output.
Performance Testing Methodology
To evaluate the V850 Sfx, we conducted a series of tests simulating real-world gaming and rendering workloads. We used Prime95 for CPU stress testing, FurMark for GPU load, and monitored voltages, temperatures, and noise levels throughout. The tests aimed to assess stability, efficiency, and thermal performance under sustained heavy loads.
Stress Test Setup
- CPU: Intel Core i7-13700K overclocked to 5.2 GHz
- GPU: NVIDIA RTX 4090
- Memory: 32GB DDR5 at 6000 MHz
- Motherboard: ASUS ROG Strix Z790-E
- Cooling: Custom liquid cooling loop
Load Performance Results
During stress testing, the V850 Sfx maintained stable voltages and efficient power delivery. The +12V rail provided consistent power within ±3% tolerance, even under maximum load. Temperatures of the power supply remained within safe limits, with the fan operating quietly at high loads, thanks to its high-quality bearings and smart fan control.
Stress Testing Outcomes
Under continuous load for over two hours, the V850 Sfx demonstrated excellent thermal management and stability. No voltage fluctuations or shutdowns occurred. The power supply’s efficiency stayed above 90%, confirming its 80 Plus Gold certification. Noise levels remained low, making it suitable for quiet PC builds.
Key Features Supporting Performance
- High-quality capacitors for durability and stability
- Smart fan control with zero RPM mode at low loads
- Over-voltage and over-current protection
- Compact SFX form factor for versatile builds
Conclusion
The Cooling Master V850 Sfx proves to be a reliable and efficient power supply, capable of handling demanding workloads with ease. Its stable voltages, thermal management, and quiet operation make it an excellent choice for high-performance gaming and professional PCs.
