The first PSU on our list is the EVGA SuperNOVA 1000 G+, 80 Plus Gold 1000W.

It’s 80 Plus Gold rated, so you don’t have to worry about energy efficiency, this one delivers. It has a 135mm Fluid Dynamic Bearing fan and it comes with a 10-year warranty.

Another great option for a PSU for the RTX 3070 is the Thermaltake Toughpower GF1 850W 80+ Gold. This power supply is also 80 Plus Gold rated, ensuring high energy efficiency, and it has a 140mm Hydraulic Bearing Smart Zero Fan it offers superior cooling performance and it operates in near silence. The smart zero feature is basically an auto-regulator. It regulates fan speed based on power consumption. The fan only works when the PSU load goes over 30%. And this is fully modular as well, so you can disconnect any cables you don’t use. Overall, the EVGA SuperNOVA 1000 G+ and the Thermaltake Toughpower GF1 are both excellent choices for a PSU for the RTX 3070, and you can’t go wrong with either one.
