NVIDIA’s latest release, the RTX 4090, has become the talk of the town due to its powerful 76.3 million transistors and 450W TDP. To run this graphics card smoothly, you need a power supply that can handle its demands. NVIDIA recommends at least an 850W power supply, but some third-party models suggest even higher wattage for GPUs with the same clock speed as the Founder’s Edition (FE) 4090.
Best PSU For NVIDIA
The EVGA Supernova 1600W Platinum is one of the best PSUs on the market today, making it an ideal choice for the RTX 4090. With 100% Japanese capacitors and a DC-DC Converter design, it provides stable 3.3V/5V. The PSU also has up to nine VGA connectors that provide more than enough space for six cables for up to two PCI-e Gen 5, 12+4 pin connectors. A 1600W power supply unit is more than enough to run an RTX 4090, and you’ll have enough headroom for other high-end requirements like CPUs, fans, cooling systems, and more.
Seasonic FOCUS GX-1000
Seasonic’s Focus GX is a budget-friendly option for the RTX 4090. It leverages extremely high-performance metrics on top of a super compact design that utilises several interesting features, like load regulation, ripple suppression, and selective semi-passive operation. The PSU also boasts a Gold certification and a 10-year warranty.

EVGA SuperNOVA 850 (P2 Series)
Nvidia recommends at least a 750W PSU for the RTX 3080, which is where the EVGA SuperNOVA P2 750W comes in. With an 80 Plus Platinum efficiency certification, it should run at about 92% efficiency when at half load. It comes at a competitive price for what you’re getting, making it an ideal choice for the RTX 3090 Ti.
Conclusion
When selecting a PSU, keep in mind that the GPU is not the only component drawing power from the PSU. You need to consider the total power your CPU needs in tandem with lighting, fans, cooling, and more. While the RTX 4090 has some intense standards, the best PSUs we have discussed will help you run it smoothly and efficiently.
In conclusion, with the help of a robust and reliable PSU, you can get the most out of your NVIDIA RTX 4090 or RTX 3090 Ti. These PSUs will provide stable power output and headroom for other high-end components, ensuring a smooth operation while gaming, streaming, or consuming casual entertainment on your computer.
