Best PSU for Nvidia RTX 4080 Super – overall, premium, and more
- Full power at higher temperatures
- Quiet operation
- Fully modular with ample connectors
- Large size may not fit compact cases
- High OCP on minor rails
- Close peripheral connector spacing
The Corsair RM850x SHIFT is an ideal choice for users seeking a balanced power supply unit for their RTX 4080 Super. This 850W PSU brings together a combination of high-quality components and practical features. It maintains full power output even at 47 degrees Celsius, ensuring reliable performance under heavy loads.
What sets the RM850x SHIFT apart is its combination of efficiency, quiet operation, and robust power delivery. The Zero RPM Fan Mode, which turns off the fan at low and medium loads, contributes to its near-silent operation, a feature especially appreciated in quiet workspaces or gaming setups. Additionally, its compliance with the ATX 3.0 standard and support for the PCIe Gen 5 platform make it, ready to handle next-generation hardware.
One potential downside is the PSU’s size, which might be a concern for compact case enthusiasts. However, this can be managed in most cases by removing the bottom hot-swap bay, which provides additional space. While the RM850x SHIFT might require some adjustment in smaller builds, its performance and feature set justify the space it occupies, making it a solid choice for those who prioritize a feature-rich and balanced PSU.
- 80 plus gold efficiency
- 1000W ample power
- PCIe 5.0 and ATX 3.0 support
- Lower efficiency under light loads
- Notably audible operation
- Bulky for compact builds
With the rise of ATX 3.0, high Wattage is a must nowadays, and MSI enters the high-end high-wattage competition with their MSI MPG A1000G. This is a perfect companion for the RTX 4080 Super mainly due to its ample power. Furthermore, the 1000W is a great choice for those looking to get the most out of the rig. Whether you’re looking to play high-end games, overclock your PC, or machine learning, this will help you out completing those tasks efficiently.
The PSU features 100% Japanese 105°C capacitors, emphasizing its focus on long-term reliability and stability. Moreover, its fully modular design is not only practical for cable management but also adds to the overall aesthetics of the build, making it an appealing choice for users who have a windowed case and care about the visual aspect of their setup.
A point to consider is the PSU’s noise level, as it falls within the 30-35 dBA range according to the Cybernetics Standard++. While this may be noticeable in very quiet environments, it is a trade-off for its high power output and efficiency. Users prioritizing a silent build might need to look at additional noise-dampening solutions or consider the noise level as part of the overall high-performance package that the A1000G offers.
- Extremely high power output
- Very low noise operation
- Excellent voltage regulation
- Less effective filtering
- Premium price point
- Large size for compact setups
For our premium pick, we decided to go with power. The RTX 4080 Super is moving the bar up for power needs, and although it’s a very efficient GPU, the type of tasks users will be able to do will require a good deed of power. Here comes the be quiet! Dark Power Pro 13 1300W. The special thing about this PSU is that it offers 1300W of power more than enough for any tasks you put it against
The Dark Power Pro 13 stands out not just for its power but also for its exceptionally quiet operation and excellent thermal performance. This makes it an ideal choice for users who prioritize a silent working environment. This along with the PSU’s fully modular design adds to a clean and organized build. Lastly, the PSU is also ATX 3.0 compliant and fully supports PCIe 5.0, making it future-proof for upcoming hardware upgrades.
While the Dark Power Pro 13 excels in many areas, its filtering capabilities might not be as robust as some other models. However, for most users and typical use cases, this should not pose a significant issue. The PSU’s overall performance, efficiency, and quiet operation far outweigh this minor shortcoming, especially considering the power it provides.
- Affordable price
- Maintains full power at high temperatures
- Ample connectivity options
- High inrush current
- Audible noise levels
- Fixed cable design limits versatility
The RTX 4080 Super is an expensive GPU, and you may have used almost all the budget on it. If that’s the case, EVGA has a great choice for you: the EVGA 850 BQ 850W. This PSU provides 850 watts of power, more than enough to support the 4080 Super, and does so at a price point that’s attractive for budget-conscious users.
The EVGA 850 BQ stands out in the budget category with features typically seen in more expensive models. It offers full power at 46°C and includes a generous array of connectors, with six PCIe and two EPS connectors, making it versatile for various builds. The PSU also excels in delivering stable power, with a good response on the +12V rail to transient loads, which is commendable for its price range.
One aspect to be mindful of is the PSU’s inrush current, which is high under both 115V and 230V inputs. While this might not be a significant concern for most users, it’s something to be aware of, especially in regions with unstable power. Despite this, the EVGA 850 BQ remains a solid choice for those looking to power a high-end GPU like the RTX 4080 Super without overspending.
Features and considerations
Given the combined TDP of the GPU and a high-end CPU like the Intel i7-13700, a PSU with at least 750W is essential. However, it’s prudent to consider PSUs that offer a bit more headroom, especially for users who plan to overclock, add additional components, or future-proof their system.
Also, look for PSUs with an 80 PLUS Gold or higher certification, as these are more efficient, converting a higher percentage of the electrical energy into power for the PC while wasting less heat. This efficiency not only saves on energy costs but also contributes to the longevity of the PSU and system components by reducing heat output.
How much power does a 4080 Super Power consume?
The NVIDIA RTX 4080 Super typically consumes around 320 watts of power. This power consumption can vary based on the specific tasks being performed and any additional overclocking. When planning a build with this GPU, it’s important to factor in the power requirements of other components as well, particularly a high-performance CPU and any other peripherals.
The Corsair RM850x SHIFT, with its balance of power and quiet operation, is an excellent all-rounder and our top pick for the Nvidia RTX 4080 Super. The MSI MPG A1000G offers a hefty 1000W for those who need extra headroom for demanding tasks. For users who prioritize premium performance and efficiency, the be quiet!
