The GTX 1660 Super is an excellent mid-range graphics card for gamers and video editors. But, there is a lot of confusion among the people about how many PSU watts they need for this 1660 GPU.
The 500 watts Power Supply would be sufficient for the GTX 1660 Super GPU when you pair all the budget-end PC components inside your system. But, if you pair top-tier CPUs or high-end PC components, then more than 500W is needed.
To estimate exactly how many PSU watts you need for this GPU, you have to calculate the other components that you will pair inside the PC with this 1660 Super GPU.
So, How Many PSU Watts Do You Need For 1660 Super?
The GTX 1660 Super consumes 175 watts from the PSU at maximum load, and many manufacturers like MSI recommend using at least a 450 watts Power Supply for this GPU.
But, it has been seen that if we pick a PSU based on the GPU specifications, then it can sometimes go wrong, and we may buy the wrong Power Supply with higher or lower wattage.
That’s why it is a good idea to calculate the required wattage of all our components and then pick the Power Supply.
According to our research,
The GTX 1660 Super requires a 450W to 500W Power Supply when you will pair this GPU with a budget-end CPU and other budget-range PC components.
The GTX 1660 Super with mid-tier CPUs and all the mid-range PC components needs a Power supply between 500W to 600W.
If you pair this GTX 1660 Super with top-tier CPUs and other high-end PC components, you need a Power Supply between 600W and 700w.
I know you are confused a little after getting this diversity of answers; that’s why checking the power consumption of all your components is important.
For your convenience, I make some lists below where you will get a clearcut idea about how many PSU watts you need when pairing the GTX 1660 Super GPU with Top-tier CPUs and high-end components, Mid-tier CPUs and mid-range components, and budget-tier CPUs and budget-range components.
But, before that, check what kind of PC components consumes how many PSU watts below-

This table would help you calculate the power consumption of all the PC components and then do the estimation.
Now, we will pair the GTX 1660 Super GPU with high-end, mid-range, and budget-end PC components and then do the estimation. So, let’s calculate the wattage-
The GTX 1660 Super With Budget-End PC Components
If you pair the GTX 1660 Super GPU with a budget-end CPU and other budget-level PC components, then the estimated power consumption would be like this-
| Components | Peak Power Consumptions |
| GTX 1660 Super | 175 watts |
| Budget-Level Intel CPUs (e.g., Intel Core i9 11900K) | 125 watts |
| Budget- Level Ryzen CPUs (e.g., Ryzen 5 3600X) | 95 watts |
| 1 SSD | 9 watts |
| 1 Hard Disk | 20 watts |
| Budget end Motherboard | 60 watts |
| 2 RAMs (8 GB) | 14 watts |
| 2 Case fans (120mm) | 12 watts |
| 1 CPU fan (120mm) | 6 watts |
| Total= 421 watts with Intel CPUs Total= 391 watts with Ryzen CPUs |
When we pair the GTX 1660 Super graphics card with the budget-end Intel CPUs and other budget-range components, our overall system’s power consumption goes up to 421 watts. In this scenario, 500 watts Power Supply is recommended. We add extra watts in case of any miscalculation happen.
Things would change when we pair this GTX 1660 Super GPU with budget-end Ryzen CPUs and other budget-range PC components; in this scenario, the overall Power consumptions go up to 391 watts, and 450 watts Power Supply would be sufficient enough for this.
GTX 1660 GPU With Mid-Range Components
If you pair the GTX 1660 Super GPU with the mid-tier CPUs and all the mid-level PC components, then the estimated power consumption would be like this-
| Components | Peak Power Consumptions |
| GTX 1660 Super | 175 watts |
| Mid-Tier Intel CPUs (e.g., Intel Core i5 13600K) | 181 watts |
| Mid- Tier Ryzen CPUs (e.g., Ryzen 7 7700X) | 105 watts |
| 1 SSD | 9 watts |
| 2 Hard Disk | 40 watts |
| Motherboard | 70 watts |
| 2 RAMs (16 GB) | 30 watts |
| 3 Case fans (120mm) | 18 watts |
| 1 CPU fan (120mm) | 6 watts |
| Total= 529 watts with Intel CPUs Total= 453 watts with Ryzen CPUs |
When we pair the GTX 1660 GPU with mid-tier CPUs and other mid-range PC components, our estimated power consumption goes up to 529 watts, and in this kind of scenario, the 600 watts Power Supply would be an excellent choice. We add extra watts in case of any miscalculation and by keeping the future upgrade factor in mind.
If we pair the GTX 1660 Super with the mid-tier Ryzen CPUs and other mid-range PC components, then the estimated power consumption would go up to 453 watts, and in this scenario, a 500 watts Power Supply would be great.
The GTX 1660 Super with High-End Components
If anyone pairs the GTX 1660 Super with a top-tier CPU and other high-end PC components, then the estimated Power Consumption would be like this-
| Components | Peak Power Consumptions |
| GTX 1660 Super | 175 watts |
| Top-Tier Intel CPUs (e.g., Intel Core i9 13900K) | 253 watts |
| Top-Tier Ryzen CPUs (e.g., Ryzen 7 7950X) | 170 watts |
| 2 SSDs | 18 watts |
| 2 Hard Disk | 40 watts |
| Motherboard | 80 watts |
| 4 RAMs (16 GB) | 60 watts |
| 3 Case fans (120mm) | 18 watts |
| 2 CPU fans (liquid cooler-120mm) | 12 watts |
| Total= 656 watts with Intel CPUs Total= 573 watts with Ryzen CPUs |
When we pair the GTX 1660 Super with top-tier CPUs and other high-end components, then the estimated power consumptions go up to 656 watts, and in this scenario, a 700 watts Power Supply would be sufficient. Of course, we add extra watts in case of any miscalculation happens.
If you pair the GTX 1660 Super with top-tier Ryzen CPUs and other high-end components, then the power consumption goes up to 573 watts, and in this kind of scenario, the 600 watts power supply is needed.
You Need More Power When You Overclock
Overclocking is the practice of increasing the clock rate of a computer to exceed that certified by the manufacturer. Many users overclock their components to maximize their PC’s performance. But, when you overclock, your components draw more power.
During overclocking, the motherboard consumes 20 to 50 watts more, the RAM consumes 2 to 3 watts more, and the SSDs and PC fans consume 1 to 2 watts more.
So, if you are going to pair this GTX 1660 Super GPU with any overclockable CPU on an overclockable motherboard, then you have to pick a Power Supply with 100 watts extra.
But you won’t need extra Power Supply watts if you are unwilling to overclock.
