When it comes to power supply units for gaming, two popular options stand out among enthusiasts: the EVGA SuperNOVA 1000 G5 and the Seasonic FOCUS GX-750. Both of these high-performance power supplies are designed to deliver reliable, efficient, and quiet operation, making them ideal for powering demanding gaming systems. In this in-depth comparison, we'll delve into the key features, specifications, and differences between these two powerhouses.

Output Capacity and Efficiency

The EVGA SuperNOVA 1000 G5 boasts a maximum output capacity of 1000 watts, with an 80 PLUS Gold certification, indicating an efficiency rating of up to 90%. This means that the power supply can convert up to 90% of the input power into usable output power, minimizing energy waste and reducing heat generation.

In contrast, the Seasonic FOCUS GX-750 has a maximum output capacity of 750 watts, also with an 80 PLUS Gold certification. While it may not match the EVGA's output capacity, the Seasonic's lower wattage makes it more suitable for systems with moderate power requirements.

Modular Cabling and Connectors

Both power supplies feature modular cabling, which allows users to connect only the necessary cables to their components, reducing clutter and improving airflow within the case. The EVGA SuperNOVA 1000 G5 has a total of 10 connectors, including:

• 1 x 24-pin ATX
• 2 x 8-pin EPS
• 4 x 6+2-pin PCIe
• 3 x SATA
• 3 x Molex

The Seasonic FOCUS GX-750 has a slightly more limited connector set, with:

• 1 x 24-pin ATX
• 1 x 8-pin EPS
• 3 x 6+2-pin PCIe
• 5 x SATA
• 2 x Molex

While the EVGA has more connectors, the Seasonic's connector layout is more optimized for smaller systems, with a focus on providing ample SATA and PCIe connections.

Cooling and Noise Levels

The EVGA SuperNOVA 1000 G5 employs a 135mm fan with a hydraulic bearing, which provides quiet operation and a long lifespan. The fan operates at a maximum speed of 2400 RPM, generating a noise level of up to 25 dBA.

In comparison, the Seasonic FOCUS GX-750 uses a smaller 120mm fan with a fluid dynamic bearing, which is designed for even quieter operation. The fan has a maximum speed of 1500 RPM and generates a noise level of up to 22 dBA. While both power supplies are relatively quiet, the Seasonic's smaller fan and optimized airflow design make it slightly more whisper-quiet.

Reliability and Warranty

Both power supplies have a reputation for reliability, with high-quality components and robust designs. The EVGA SuperNOVA 1000 G5 is backed by a 10-year warranty, while the Seasonic FOCUS GX-750 comes with a 10-year warranty as well.

Conclusion

In conclusion, both the EVGA SuperNOVA 1000 G5 and the Seasonic FOCUS GX-750 are excellent power supply units for gaming, offering high efficiency, reliable operation, and quiet performance. The EVGA's higher output capacity makes it more suitable for demanding systems with multiple graphics cards or high-wattage CPUs.

On the other hand, the Seasonic FOCUS GX-750 is a great option for those with more moderate power requirements, offering a slightly more compact design and optimized connector layout. While both power supplies are 80 PLUS Gold certified, the EVGA's higher wattage and more extensive connector set make it a better choice for enthusiasts who require maximum power and flexibility.

Ultimately, when selecting between these two power supply units for gaming, consider your system's specific power requirements, case size, and desired level of future upgradability. Whether you choose the EVGA SuperNOVA 1000 G5 or the Seasonic FOCUS GX-750, rest assured that you'll be getting a high-quality power supply that will deliver reliable performance and quiet operation for years to come.
