Who it fits
Good fit for
This unit suits users with high-end multi-GPU setups or extreme overclocking needs. The 1300W rating provides ample headroom for future upgrades. The 8x4x6 inch size fits most standard mid-tower and full-tower cases. If you need reliable power for a workstation or a gaming rig with many components, this spec sheet supports that choice. The internal design is standard for desktop PCs.
Who should skip it
Skip this model if your case has a small form factor constraint. The 8x4x6 inch dimensions may not fit in compact chassis designed for lower profile units. Users with low-power builds do not need 1300W capacity. You would be paying for unused power headroom. Consider a lower wattage unit if your system draws less than 800W. This product is not for mini-ITX builds with tight space limits.
Verdict: The EVGA Supernova G2 1300W is a high-capacity unit for demanding builds. Its specs support heavy workloads and future expansion.

Ensure your case layout can handle the 8 by 4 by 6-inch form factor for optimal airflow and installation ease.
Setup and Daily Use Guide
Setting up this EVGA Supernova G2 requires careful planning due to its physical footprint. The unit measures 8 inches wide, 4 inches high, and 6 inches long. You must verify that your computer case has sufficient internal volume to accommodate these dimensions. A cramped chassis may not provide the necessary clearance for installation. The power supply weighs 7 pounds. This mass suggests a sturdy internal construction, which can help stabilize the unit within your system frame during operation.
This 1300W power supply is designed for high-end builds. It delivers 3.3 V DC at 24 A and 5 V DC at 24 A. These voltage rails support demanding components. You should connect high-performance graphics cards and multiple processors to this unit. The 1300W rating ensures that your system receives consistent power even under heavy load. This capacity prevents strain on individual components during intensive tasks.
Everyday use involves connecting compatible cables to your motherboard and peripherals. The model number 120-G2-1300-X identifies this specific revision. You should ensure your case supports the input voltage range of 110 V AC or 220 V AC. Proper airflow around the 8-inch width is essential for thermal management. The design prioritizes stability and power delivery for enthusiast systems. You will need to route cables carefully to maintain the 6-inch depth clearance. This setup process ensures reliable performance for your high-wattage components.
Before You Buy This Unit
You need to verify case compatibility before ordering. The EVGA Supernova G2 1300W Power Supply measures 8 inches wide, 4 inches high, and 6 inches long. Your chassis must have enough internal volume to fit these dimensions. A cramped case will block airflow or prevent installation. You should also check your power cables. This unit requires appropriate connectors for your high-end graphics cards and processors. Ensure your motherboard and components support the input voltage of 110 V AC or 220 V AC. Regular upkeep involves keeping the unit free of dust. Dust buildup can reduce efficiency and increase noise. This power supply fits alongside other high-wattage options in our guide. It suits users who need maximum continuous power. If your system draws less power, a lower wattage unit may be more cost-effective. Always compare the physical size against your specific case model.
