Best PSUs for the Nvidia GeForce RTX 3060 Ti and AMD Ryzen 5 5600X Build

Perhaps one of the best combinations, for a pure-gaming PC build, is AMD’s Ryzen 5 5600X CPU together with Nvidia’s GeForce RTX 3060 Ti. These two components can offer excellent 1080p gaming with high framerates at just a fraction of the cost of what such performance used to be valued at just a few months ago.

Given that the GeForce RTX 3060 Ti has only a 200-Watt Thermal Design Power (TDP) requirement, and Ryzen 5 5600X’s 65 W TDP, a Power Supply Unit (PSU) capable of outputting 650 Watts will work just fine for providing energy to a build that features these two components. In fact, one may argue that 650 W may be a bit too much, but it’s always better to have more power output capability, rather than less, as a PSU will operate at optimal efficiency at around 50% loads.

Hence why we’ve chosen the best 650 Watt PSUs for you to pair with the GeForce RTX 3060 Ti and Ryzen 5 5600X, depending on your needs and preferences.

Gigabyte P650B

Best Budget PSU

Output Wattage650 Watts
Item Dimensions LxWxH5.91 x 5.51 x 3.39 inches
Fan Size120 Millimeters

Whether you’ve appropriated most of your budget for this new CPU and GPU pairing, or simply won’t be using your PC for several hours a day, an 80 PLUS Bronze-rated PSU will suit your needs perfectly well. For this case, we have the Gigabyte P650B which has all the specifications of a premium PSU, at a budget price.

Firstly, it has a single +12V rail that can output nearly all of its wattage: 648 W (54 amps) to be precise, so both the R5 5600X and the RTX 3060 Ti will have sufficient energy to operate optimally. The P650B also has all-Japanese Nippon Chemi-Con, 105-degree C certified capacitors, sleeved cables (non-modular), and a 120 mm fan that uses high-end hydraulic bearings. Having these bearings not only means that the PSU is more durable, but also that it will operate quietly, no matter what load it is under. In fact, the P650B has a Mean Time Between Failures (MTBF) of 100,000 hours, and this is backed by Gigabyte’s 3-year warranty.

The Gigabyte P650 can currently be found for only $69.99, down slightly from its original $74.99 MSRP.
