The RTX 3060 might not be the strongest addition to Nvidia’s Geforce RTX 30 series, but it’s certainly powerful enough to satisfy those who are looking for a mid-range build. Designed to compete with the top GPUs from the RTX 20 series, the RTX 3060 becomes one of the most affordable mid-range graphics cards out there if you can get it at MSRP. Now, the question is- what does it take to power it? Will an older PSU still work? Let’s find out by exploring the 8 best PSUs for RTX 3060.
RTX 3060 PSU Requirements
According to Nvidia, the RTX 3060 has a TDP of 170W, which is 30W less than its TI variant. This translates to lower power requirements than what we’ve seen with the previous generations of Nvidia GPUs as well as the rest of the RTX 30 series.
As far as power supplies are concerned, Nvidia recommends a minimum of 550W. However, if you plan to overclock the GPU or pair it with a demanding CPU, you should consider a 600-650W PSU instead with a good efficiency rating. It all depends on your overall PC configuration, so make sure to take each component into account and leave some headroom for safety. We’re going to explore a series of 600-650W power supplies since the RTX 3060 is best suited for a midrange system.
1. EVGA SuperNOVA 650 P2Form factor: ATX | Capacity: 650W | Efficiency rating: 80 Plus Platinum | Modularity: Full | Warranty: 10 years

The P2 series from EVGA is known as the Mercedes class of power supplies. It offers Platinum-rated performance and it’s built to last. This is a luxury PSU. It is powerful and it will have no trouble handling an RTX 3060, however, you probably won’t notice that platinum efficiency. Theoretically, that translates to a 3% increase in efficiency compared to a standard gold-rated power supply. If all you care about is power, you’ll find cheaper alternatives on our list.
On the other hand, EVGA packed several valuable features into the design of the P2 series and they offer a hard-to-beat 10-year warranty. This 650W PSU is fully modular, thus eliminating clutter as much as possible and improving the airflow inside the case. This feature alone justifies the price tag because it has a significant impact on your overall setup. After all, you don’t want to run every piece of hardware hotter than necessary just because there are entangled cables everywhere.
Like any other premium power supply, the P2 is also equipped with an ECO fan system that keeps the PSU operating with zero fan noise under low to medium loads. This feature combined with the sizable 140mm double ball-bearing fan will guarantee quiet operation. Furthermore, the package includes a free 24-pin power tester, velcro cable ties, and a bag to store all the extra cables you don’t need for your setup.
All in all, the P2 offers a lot of value and reliable performance. It’s one of the best power supplies for those who are looking for a hassle-free solution.
