EVGA SuperNOVA 750 GT review

When people talk about PC components, conversation usually revolves around the central processing unit (CPU), random access memory (RAM), and the graphics processing unit (GPU). One of the most important components to a PC is the power supply unit (PSU) however it is often one of the last things people think about in their PC. Often people assume that all you need is a high wattage PSU to provide power to the PC components. While this is true, there is much more to consider when looking at a PSU that will run quietly, efficiently, and have a long life. Today I will be reviewing the EVGA SuperNOVA 750 GT. 

Why you need a new power supply

Before beginning the review, let’s talk about why you might need a new PSU. There are a few reasons why you might need a new power supply. First, you may be upgrading PC components which require more power to function. For example, the EVGA GeForce RTX 3080 graphics card requires a minimum of a 750w PSU. If your current PSU is lower than 750w you will need to purchase a new unit. Second, you may be adding more components to your PC. An example of this could be adding more storage space, RGB LEDs, cooling systems, and USB peripherals. The addition of more components will draw more power and may require a higher wattage PSU. Third, you may be building a new PC and are looking for a PSU to match your PC’s needs.

In my case, a combination of reasons 1 and 2 meant that I needed a higher wattage PSU. To breathe new life into my aging PC I decided to do a few things. In order to boost the raw power of my PC I decided to overclock my CPU and at the same I purchased a new RTX 3070 GPU. In addition to this I also added more RAM and storage space. To keep my computer running cool I installed 3 additional RGB case fans. All of these changes meant that my old 650w PSU would not be able to provide enough power for the PC to run quietly and effectively.

Testing of the EVGA SuperNOVA 750 GT was done on my personal PC which includes the following specs.

• 1x CPU i7-7700k overclocked
• 2x GPUs Asus Dual RTX 3070 and EVGA GeForce GT710
• 2x solid state storage
• 1x hard drive
• 1x optical drive
• 6x 120mm RGB case fans
• 6x USB connected devices

What’s inside the box

EVGA kept the packaging simple with the SuperNOVA 750 GT. Inside the box you will find the EVGA 750 GT PSU, instruction manuals, mounting screws, and power cables. The 750 GT’s body is a hefty 6lbs. EVGA made sure to protect the 750 GT from bumps and bruises by encasing it in sturdy foam. 

Easy installation and organization

Installing the EVGA SuperNOVA 750 GT was simple and straightforward. I was pleasantly surprised to find that EVGA had printed the name of the matching component on the cable and on the PSU body. This was helpful in reducing confusion and making sure that cables were connected properly. For example, to the casual observer the six pin CPU and GPU cables can easily be confused. However, EVGA clears this confusion by printing the label “CPU” on the power cable as well as on the PSU body.

The 750 GT’s completely modular design also makes installation and organization simple. When selecting cables, I only needed to set aside the power cables that would be used. Any cables that I didn’t need were stored away. A benefit of the 750 GT’s modular design is that you can connect the power cables to the PC components first before finally connecting them to the 6lb PSU body. This makes it easier to maneuver the cables within the PC case. Additionally, having the cables free from the PSU body makes organizing and routing the cables within the PC case easier.

After attaching the power cables to the PC components the next step is connecting the power cables to the 750 GT body. Again this was simple to do, connecting the power cables to the PSU body is just a matter of matching up the labels. The final step in the installation of the 750 GT is securing the unit to the PC case using the included philips head screws.

Quiet and efficient operation

The EVGA SuperNOVA 750 GT has a 80 plus certification with a gold rating. Let’s do a quick review of the 80 plus certification. To receive the 80 PLUS certification a PSU needs to have a minimum of 80% power efficiency while under various operating loads. Because  PSU’s use different components they have varying levels of efficiency. In order to categorize the levels of power efficiency a rating system is used. This rating system categorizes a PSU’s efficiency as bronze, silver, gold, platinum, or titanium. In the case of the EVGA SuperNOVA 750 GT, the gold rating means that it is 87% efficient. This makes it more efficient than the basic 80% required to receive a 80 plus certification.

During operation the EVGA SuperNOVA 750 GT is quiet with little to no noise. This is due to the auto eco control system and the large 150mm fluid dynamic bearing (FDB) fan. The auto eco control system monitors the 750 GT’s operational load and temperatures. During times of low or moderate operational loads the auto eco control system will shut off the fan.This results in less noise, reduced wear on the fan bearing, and reduced power consumption. Likewise, if temperatures rise or operational loads increase the 750 GT’s fan will start up. Even though the fan is running the 750 GT remains silent due to its FDB design. In addition to FDB fan designs running silently, they are able to push more air, and have longer life spans than other fan designs. 

Another benefit of the EVGA SuperNova 750 GT is its large fan size. While other PSU’s may use a 120mm size fan the 750 GT is equipped with a 150mm fan. Due to its larger size the 150mm fan is able to move more air into the PSU keeping the 750 GT cooler and more quiet. In my stress tests I had my PC running Call of Duty Warzone at medium to high settings with multiple applications open. Even at high loads I was still unable to hear the 750 GT operating even when I stood right beside the PC case.

Final thoughts on the EVGA SuperNOVA 750 GT

I was pleasantly surprised at how much I liked the EVGA SuperNOVA 750 GT. Installation was enjoyable and straightforward due to the clear labelling and fully modular design. I was also very surprised at the 750 GT’s silent operation even under high loads. For anyone considering upgrading or purchasing a new PSU I would strongly recommend looking at the EVGA SuperNOVA 750 GT. For those of you who need a PSU with slightly higher wattage you should also consider the 850w EVGA SuperNOVA 850 GT.
