Best PSU for RTX 3070 Ti Buying Guide:

The RTX 3070 Ti is the most recent graphics card in Nvidia’s Ampere series of cards. However, it needs a power supply of at least 750 watts, and it needs 290 watts to operate on its own. Therefore, we recommend that you buy a power supply unit with at least 750 watts of power to make sure your RTX 3070 Ti is sufficiently powered. 

Here are some basic specifications you’ll want to make sure your PSU has before purchasing one for this particular model.

80 Plus Certification:

The 80 PLUS certification program is a voluntary one that manufacturers can utilize to provide consumers with some assurances. The company rates power supplies and guarantees their efficiency levels with various labels ranging from basic, gold, silver, etc. The efficiency rating of your power supply is the key factor in determining how much energy will be consumed. A higher number indicates a more efficient and environmentally friendly product, but you should also consider other factors like wattage before making any final decisions on which to buy.


A modern power supply is required to output 18A (amps) on the +12V rail(s), and more than 24A if a single enthusiast-class graphics card, or no less than 34. Therefore, if you want your computer system to run smoothly with all of its components powered up at once, then it’s important that you make sure that there are enough amps available for each component from the rails in your PC’sPC’s PSU.

Form Factor:

Your power supply size is a critical decision, but one that will ultimately come down to personal preference. There are three main factors you’ll need to consider: the kind of case you’re using, what motherboard type it has (ATX or Micro ATX), and how many graphics cards or hard drives do you want? Of course, the most important point in this process is making sure the PSU matches those requirements, so take note before buying! 


Power supplies generate heat, which means they require fans to stay cool. You’llYou’ll want to give some thought to how quiet you want your PC running, and this will be determined a lot by the environment that it is in. If operating in a quieter space, then larger fans with slower blades may result in less noise, but loudness won’t matter if there’s already an ambient level of sound around. As long as the power supply keeps up its performance efficiency levels for high-quality gaming or streaming video content without overheating itself.
