The NVIDIA GeForce RTX 1660 Super is a popular mid-range graphics card that packs a punch when it comes to gaming performance. However, to get the most out of this powerful GPU, you’ll need a power supply unit (PSU) that can deliver clean and stable power. The question on many gamers’ minds is: is 400W enough to power the RTX 1660 Super?
Understanding Power Requirements
Before we dive into the specifics of the RTX 1660 Super’s power requirements, it’s essential to understand how power supply units work. A PSU’s wattage rating indicates its maximum power output, but that doesn’t mean it’s always drawing that amount of power. The power consumption of a system depends on various factors, including the GPU, CPU, RAM, and storage.
The RTX 1660 Super has a TDP (thermal design power) of 125W, which is relatively low compared to higher-end graphics cards. However, this doesn’t mean you can get away with a low-wattage PSU. The TDP only accounts for the GPU’s power consumption, not the entire system.
Calculating System Power Requirements
To determine the minimum PSU wattage required for your system, you’ll need to calculate the total power draw of your components. Here’s a rough estimate of the power consumption of typical system components:
- CPU: 65W (mid-range)
- Motherboard: 10W
- RAM: 10W (16GB)
- Storage: 10W (SSD)
- GPU (RTX 1660 Super): 125W
- Case fans: 10W (2 fans)
- Total power draw: 230W
As you can see, the total power draw is already above 200W, and this doesn’t account for any additional components like hard drives, fans, or peripherals. A 400W PSU may seem sufficient, but it’s essential to leave some headroom for power spikes and overclocking.
Headroom and Overhead
When choosing a PSU, it’s crucial to consider headroom and overhead. Headroom refers to the amount of power available above the system’s total power draw. This ensures that your PSU can handle power spikes and overclocking without shutting down or causing instability.
A general rule of thumb is to have at least 10-20% headroom above the system’s total power draw. Based on our previous calculation, this would mean:
- Total power draw: 230W
- Headroom: 23-46W (10-20% of 230W)
- Minimum PSU wattage: 253-276W
As you can see, a 400W PSU barely meets the minimum requirement, leaving little room for overhead. Overhead refers to the PSU’s ability to handle sudden power spikes or increased power draw during intense gaming sessions or overclocking.
Power Quality and Efficiency
Power quality and efficiency are also critical factors to consider when choosing a PSU. A high-quality PSU with a high efficiency rating (e.g., 80 PLUS Gold or higher) will waste less energy as heat and provide a more stable power output.
Look for a PSU with a high PF (power factor) rating, which indicates its ability to handle AC power and provide a stable DC output. A high PF rating ensures that your PSU can handle the power requirements of your system without compromising on efficiency.
Conclusion: Is 400W Enough for the RTX 1660 Super?
In conclusion, while a 400W PSU may be sufficient for the RTX 1660 Super, it’s essential to consider the total power draw of your system and leave some headroom for power spikes and overclocking. A 550W or higher PSU would provide a safer margin and ensure that your system remains stable even during intense gaming sessions.
Remember, a PSU’s wattage rating is not the only factor to consider. Look for a high-quality PSU with a high efficiency rating, high PF rating, and sufficient headroom to ensure a stable and reliable power output.
Recommendations
If you’re building a system around the RTX 1660 Super, we recommend the following PSUs:
- EVGA 550 GS, 80+ Gold 550W
- Corsair CX550M, 80+ Bronze 550W
- Seasonic FOCUS GX-550, 80+ Gold 550W
These PSUs offer a good balance of power, efficiency, and quality, ensuring that your system receives a stable and reliable power output.
Final Thoughts
When it comes to powering the RTX 1660 Super, it’s essential to prioritize power quality, efficiency, and headroom. While a 400W PSU may seem sufficient, it’s better to err on the side of caution and opt for a higher-wattage PSU to ensure a stable and reliable power output.
By considering the total power draw of your system, headroom, overhead, power quality, and efficiency, you can make an informed decision when choosing a PSU for your RTX 1660 Super-powered build.
