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 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 its 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.

Best Budget PSU – Gigabyte P650B

Gigabyte P650B

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 the 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.

For this case, we have the Super Flower Leadex III. This power supply has a 80 PLUS Gold rating (translating to an efficiency level of 87% to 90%) and a high power +12V rail that can output 649.2 watts, or 54.1 amps. Like the aforementioned Gigabyte model, it also has 105-degree Celsius certified Japanese capacitors, and the power supply has been tested to not faulter even after 2,000 on/off switches.

The Leadex III is cooled by a 130 mm fan that makes use of contactless hydro-dynamic bearings and PWM controls, so temperatures and noise levels will be low no matter how busy the PSU is. Also note, the Leadex III is fully modular, so all cables can be removed and attached according to your needs.

Lest we forget, the Leadex III has two ARGB displays: A illuminated I/O crystal-designed panel and an ARGB illuminated fan with translucent blades. These RGB displays can be synchronized using any motherboard manufacturer synchronization software.

Seasonic’s FOCUS SGX-650 offers amazing performance and versatility in a small form factor – and a very reasonable price.

Firstly, it has a single +12V rail that can output 54 Amps (or 648 Watts) with an 80 Plus Gold certification; similar to the Leadex III. Also, it includes a 120 mm fan (which is huge for a SFX PSU) that makes use of premium fluid dynamic fan bearings, for low noise use and optimal durability, as well as PWM controls. The SGX-650 also has gold plated connecters, a cable-free internal connection design, a SFX to ATX bracket (for those that need a small PSU for a full ATX case), un-sleeved cables for better flexibility (fully modular), and a MTBF of 100,000 hours that is backed by an impressive 10-year warranty.

So, if you need a small form factor PSU, the Seasonic FOCUS GSX-650 is the way to go, and you can currently find it for $121.99 – down from its original $169.99 price-tag.
