Who it fits
Good fit for
This power supply suits users building high-performance workstations or gaming rigs that require substantial power. The 1300W capacity supports multiple GPUs, making it ideal for NVIDIA SLI or Crossfire setups. Its fully modular design benefits builders who value cable management and airflow. The 80 PLUS Gold rating ensures lower energy waste, which is helpful for systems running under heavy loads for extended periods. If you need a reliable, high-wattage unit with a long warranty, this model fits your needs.
Who should skip it
You should look at another option if you have a modest budget or a low-power system. The 1300W output is excessive for standard office PCs or entry-level gaming builds. Additionally, the large physical dimensions, measuring 12 inches in width and 11.2 inches in height, may not fit in smaller cases. If you prefer a non-modular design for simplicity, this fully modular unit adds unnecessary complexity. Users needing a compact form factor will find this unit too bulky for their chassis.
Verdict: The EVGA SuperNOVA G2 1300W is a robust, high-capacity power supply for demanding builds. Its gold efficiency and long warranty make it a solid choice for enthusiasts.
Key specs explained
Wattage: 1300W
This power supply delivers 1300 watts of continuous power. You need this capacity for systems with high-end graphics cards and multiple components. It ensures stable power delivery under heavy loads. If you build a workstation or gaming PC with top-tier hardware, this output prevents bottlenecks. Lower wattage units might struggle with such demanding setups.
Efficiency Rating: 80 PLUS Gold
The unit converts at least 90% of AC power to DC power under typical loads. This reduces electricity waste and heat generation. You benefit from lower energy bills and a cooler running system. This rating is higher than standard Bronze units. It is ideal for users who want efficient power conversion without paying for Platinum or Titanium tiers.
Modularity: Fully Modular
All cables are detachable from the power supply unit. You only connect the cables your system actually uses. This improves airflow inside your case by reducing cable clutter. It also makes installation easier and maintenance simpler. If you prefer clean builds or have limited space, this feature helps you manage wires effectively compared to non-modular designs.
Fan Size: 140mm
The cooling fan measures 140 millimeters in diameter. Larger fans can move more air at lower speeds than smaller fans. This results in quieter operation during normal use. You get effective cooling without high noise levels. This is preferable to units with smaller 120mm fans that must spin faster to dissipate the same amount of heat.
Warranty: 10 Year
EVGA provides a ten-year warranty for this power supply. This covers manufacturing defects and ensures long-term reliability. You have peace of mind for a decade of use. This duration is longer than many standard units. It signals confidence in the product's build quality and durability for users planning to keep their PC for many years.
Physical Design and Build Quality
The EVGA SuperNOVA G2 1300W is a fully modular power supply unit. According to the listing, it features a black finish and measures 12 inches in width, 11.2 inches in height, and 7.4 inches in length. This form factor is standard for ATX cases. It weighs 8 pounds, which suggests a solid internal construction using substantial materials. The size allows it to fit into most mid-tower and full-tower chassis without issue. However, you should verify your case dimensions before installation to ensure adequate clearance.
The unit uses a 140mm double ball bearing fan. This larger fan size typically allows for quieter operation at lower speeds compared to smaller fans. It is designed to handle the thermal output of a 1300W system efficiently. The 80 PLUS Gold certification indicates high energy efficiency, reaching up to 90% under typical loads. This reduces waste heat and power consumption during operation. You benefit from lower electricity costs and a cooler-running system.
Safety is addressed through heavy-duty protections. The listing specifies OVP, UVP, OCP, OPP, and SCP safeguards. These features protect your components from voltage spikes, overcurrent, and short circuits. The fully modular design lets you connect only the cables you need. This improves airflow and cable management inside your case. You should use only the included cables, as third-party options may cause power issues. The 10-year warranty provides long-term reliability assurance for your build.
Setup and Everyday Use Guide
Installing this fully modular unit requires careful cable management. You must use only the cables included with the product. Using third-party cables can lead to issues with not powering on. This strict requirement simplifies your setup process but limits customization options. The 140mm double ball bearing fan is a key component for daily operation. It helps manage heat while maintaining system stability. The unit delivers up to 90% efficiency under typical loads. This high efficiency rating means less wasted energy and lower heat output during everyday tasks. Heavy-duty protections are built into the design. These include over-voltage, under-voltage, over-current, over-power, and short-circuit protections. These features safeguard your components during unexpected power events. The 1300W capacity supports demanding builds. You can connect high-end graphics cards and multiple storage drives without worrying about insufficient power. The unit is ready for NVIDIA SLI and Crossfire configurations. This compatibility ensures you can run multi-GPU setups if your workflow requires it. The 10-year warranty provides long-term assurance. It reflects the manufacturer's confidence in the product's durability. For daily use, the fully modular design allows you to remove unused cables. This keeps your case interior clean and improves airflow. The black finish blends well with most modern PC cases. The physical dimensions fit standard ATX cases. You do not need special mounting hardware beyond what is typically included with your case. The unit operates quietly under normal loads. The double ball bearing fan is designed for longevity. It reduces the need for frequent maintenance. Overall, the setup is straightforward if you follow the included cable instructions. The daily performance is reliable and efficient.
Before You Buy This PSU
Before you finalize this purchase, verify your system’s physical constraints. The unit measures 12 inches wide, 11.2 inches high, and 7.4 inches long. Ensure your case accommodates these dimensions without blocking airflow. You must also confirm your motherboard supports the required connectors for a 1300W load. High-end graphics cards and multiple drives draw significant power. This supply handles that load efficiently thanks to its 80 PLUS Gold certification. You will benefit from reduced heat output and lower energy waste. Keep the area around the 140mm double ball bearing fan clear of dust. Regular cleaning maintains optimal airflow and prevents bearing wear. This model sits alongside other high-capacity options in the market. It offers robust protections against voltage spikes and short circuits. Choose this unit if you prioritize stability and efficiency for a demanding build.
