The fully modular design of the EVGA SuperNOVA 1300 GT was a key factor in my decision. I required a reliable power supply for my powerful system but didn’t want a complicated setup. Here’s my take on the modular design:

  • Less clutter: Only cables that are necessary are connected, leaving more open space inside the case.

  • Improved Airflow: With fewer cables, there’s better air circulation, thus reducing the overall temperature of my system.

  • Improved cable organization: Managing cables is now a more straightforward process.

  • Versatile use of space: The additional room allows for more flexibility in component placement or even future upgrades.

When unboxing the SuperNOVA 1300 GT, I appreciated the minimal cabling right away. The clearly labeled and black cables were orderly arranged, enabling me to select only the necessary ones for my setup. This customization reduced clutter inside the case, enhancing airflow noticeably.

However, even with its advantages, building a PC using separate components comes with challenges. You must be cautious not to lose any cables as they could be necessary later on. Additionally, determining which cables go where during the initial setup can be confusing if you’re new to PC construction.

Installing the PSU was fairly straightforward. Each port on the power supply is clearly marked, so I had confidence in where to plug everything. This clarity sped up the installation process and made it less prone to errors. In my case, it was a breeze to set up, and it fit perfectly in my ATX case form factor.

I appreciate the design’s role in creating a neater appearance. My internal components now look organized and appealing, which is significant since my case features a transparent side panel. The advantages extend beyond looks; temperatures within the case have improved due to the enhanced airflow of a modular layout.

The fully modular setup is, thus, a double-edged sword. On one hand, it’s a dream for clean builds and efficient cooling. On the other, it commands some organization and responsibility in cable management. For me, the positives far outweigh any negatives, and the improvement in airflow is noticeable. The SuperNOVA 1300 GT is a testament to how a thoughtfully designed PSU can contribute to not just the power, but also the overall health and maintenance of your PC.
