EVGA G3 850W Efficiency and Noise Levels
Two of the most important factors in power supplies are efficiency and noise levels. The EVGA SuperNOVA G3 850W power supply stands out in both areas, but let’s break down exactly what you can expect.
Efficiency
The EVGA G3 850W power supply is 80 Plus Gold certified, a mark of high efficiency. Here’s what that means in practical terms:
At 20% Load: The G3 850W delivers at least 87% efficiency. This means that when your system runs light tasks, only 13% of the power drawn is lost as heat, making it quite energy-efficient.
At 50% Load: Efficiency peaks at 90%. This is typically where most gaming and high-performance systems operate during normal use, so you’re getting the best performance with minimal wasted energy.
At 100% Load: The G3 850W maintains 87% efficiency even under full load. This ensures that the power supply remains highly efficient even when your system is pushed to its limits.
Specific Efficiency Ratings: Under typical loads, the power supply achieves 90% efficiency at 115V and an impressive 92% at 220-240V. This benefits users in regions with higher voltage standards, ensuring consistent performance.
Professional reviews have consistently praised the G3 850W for its outstanding voltage regulation. The power supply manages to keep voltage fluctuations within ±1%, even under full load, which is crucial for the stability and longevity of your components.
Noise Levels
While efficiency is a strong point, the noise levels of the EVGA G3 850W are a bit more complex. Here’s what you need to know:
ECO Mode: The G3 850W has an ECO mode that reduces fan noise by turning off the fan at low to medium loads. While this can be effective in quieter operations during light tasks, it has some drawbacks.
Fan Noise: When ECO mode is enabled, many users have reported that it can become quite loud when it kicks in. The fan tends to ramp up to high RPMs quickly and with little warning, which can be quite jarring.
User Recommendations: If you prioritize a quieter system, many users and reviewers suggest disabling the ECO mode. This allows the fan to run continuously at lower RPMs, providing a more consistent, less intrusive noise level. This way, the noise is more predictable and generally quieter than the abrupt spin-ups when ECO mode is on.
EVGA G3 850W Performance Under Heavy Load
When it comes to powering high-end gaming PCs and workstations, the EVGA G3 850W power supply stands out. Here’s a closer look at its performance under heavy load.
Continuous Output
The EVGA G3 850W is designed for a continuous output of 850W on the 12V rail. This makes it ideal for powering demanding systems with powerful GPUs and CPUs, ensuring they get the consistent power they need for optimal performance.
High-Quality Components
Equipped with high-quality Japanese capacitors rated for high temperatures, the G3 850W ensures reliability even under sustained heavy loads. These capacitors are crucial for maintaining stability and longevity in demanding conditions.
Over-Power Protection (OPP)
While there have been some concerns about the OPP settings being slightly high, the G3 850W is generally praised for handling its maximum rated load without issues. Most reviews highlight its ability to maintain performance and efficiency under heavy loads.
