Key specs explained for EVGA
Wattage: 1300W
This value indicates the maximum continuous power the unit can supply to your components. A 1300W rating provides significant headroom for high-end graphics cards and multi-core processors. You benefit from stable voltage delivery even during peak loads. When shopping, compare this against your system’s total power draw to ensure you have enough capacity for future upgrades without risking instability.
Efficiency Rating: 80 PLUS Gold
This certification means the power supply converts at least 90% of AC input power to DC output under typical loads. Higher efficiency reduces wasted energy as heat, lowering your electricity costs. You get a cooler-running system with less strain on your cooling fans. Compare this against 80 PLUS Bronze or Platinum units to balance performance needs with energy savings in your build.
Modularity: Fully Modular
This feature allows you to detach all cables from the power supply unit. You only connect the cables your specific components require, which reduces cable clutter inside your case. Better airflow results from fewer obstructing wires. You benefit from easier installation and cleaner aesthetics. When comparing, choose fully modular units for tight cases or builds where cable management is a priority over fixed-cable simplicity.
Warranty: 10 Year
This duration represents the manufacturer’s commitment to replace or repair the unit if it fails within ten years. A longer warranty often reflects higher component quality and reliability. You gain peace of mind for long-term use without worrying about early failure. Compare this against standard five-year warranties to assess the manufacturer’s confidence in their product’s durability and lifespan for your investment.
Build Quality and Physical Design
The listing describes this unit as fully modular. This design choice allows you to connect only the cables you need. It reduces cable clutter inside your case. This improves airflow and makes cable management easier. The internal construction uses 100% Japanese capacitors. It also features a DC-DC converter design. These components aim to improve stability on the 3.3V and 5V rails. This is important for sensitive peripherals.
According to the listing, the dimensions are 5.9 inches wide, 7.87 inches high, and 3.4 inches long. The unit weighs 5 pounds. These measurements fit standard ATX cases. The 3.4-inch depth is compact. It helps when installing the unit in smaller chassis. You should verify your case supports this length before purchasing.
The fan uses a fluid dynamic bearing. This design supports ultra-quiet operation and increased lifespan. The unit includes EVGA ECO Mode. This feature reduces noise under light loads. The operating temperature range is 0° to 50° C. This allows use in moderately warm environments. The finish and materials are not detailed beyond these internal components. The modular design remains the primary physical feature you will notice during installation.
Setup And Daily Operation Guide
Setting up this EVGA Supernova 1300 G+ begins with selecting the correct cables. Because the unit is fully modular, you only need to connect the cables required for your specific build. This approach reduces internal clutter and improves airflow within your case. The physical dimensions are 7.87 inches in height, 5.9 inches in width, and 3.4 inches in length. You should verify that your PC case has sufficient space for these measurements before installation. The unit weighs five pounds, which is typical for high-capacity power supplies. Once installed, the power-on self-tester included with the package allows you to verify basic functionality before connecting it to your main system components. This feature helps confirm the unit is operational without requiring a full system boot. Daily operation is influenced by the fluid dynamic bearing fan and the ECO Mode. The ECO Mode enables ultra-quiet operation by stopping the fan under low loads. This design choice increases the lifespan of the fan bearing. The operating temperature range is specified as 0° to 50° C. You must ensure your case provides adequate ventilation to keep the internal temperature within this range. The 80 PLUS Gold certification indicates that the unit maintains 90% efficiency or higher under typical loads. This efficiency reduces heat generation during normal use. The DC-DC converter design improves stability for the 3.3V and 5V rails. This stability is crucial for supporting modern motherboards and peripherals. The 10-year warranty provides long-term coverage for your investment. You can rely on this support if issues arise during the product's lifecycle.
Before You Buy This Unit
You need a case with enough space for this 1300W unit. The dimensions are 5.9 inches wide, 7.87 inches high, and 3.4 inches long. Verify your chassis can accommodate this size. The 1300W rating suits high-end builds. You should ensure your motherboard and GPU connectors match the included cables. The unit includes a free power-on self-tester. You can use this tool to verify functionality before final installation. Keep the area around the fan clear for airflow. The operating temperature range is 0° to 50° C. Avoid placing it in enclosed spaces without ventilation. This model sits alongside the 1600W variation. Choose based on your actual power needs. The fully modular design helps manage cable clutter. Regular dust cleaning maintains efficiency. Check your component power requirements against the 1300W limit. This ensures stable performance under load.
Check before you buy
- Verify your case fits the 5.9 by 7.87 by 3.4 inch dimensions.
- Confirm your components stay within the 1300W total power limit.
- Ensure you have enough modular cables for all required connections.
- Check that your case allows airflow for the 0 to 50 C range.
