RTX 3090 Ti PSU Requirements

Nvidia’s RTX 3090 Ti has some hefty power requirements, and you’ll need a powerful PSU to keep it running at optimal performance. Nvidia recommends a minimum of 750W, but you can’t go wrong with a more powerful one especially if you have other high-powered components like a CPU in your build. In this article, we’ll take a look at some of the best rtx 3090 ti psu requirements.

If you’re building a mid-range PC with the RTX 3090 Ti and an i9-12900k then you can easily run it with a 750W PSU if you have no other power-hungry drives or LED lighting. However, make sure that the power supply has a good continuous power rating and doesn’t just advertise its peak ratings. The better ones will provide a much more stable stream of power throughout the system. You’ll also want a PSU with overvoltage protection and short circuit protection to protect your expensive components from damage or failure.

The i5-12400 and Ryzen 5 5600X are the appropriate CPUs for this GPU, and both can pull momentary peaks of 140W for a fraction of a second during particularly demanding sections of a game but won’t do so consistently or frequently. Using these estimates as a guideline, a 550W or higher power supply is more than enough for the combo and should leave you with plenty of headroom for any future upgrades. In fact, it’s a good idea to aim higher than this amount so that you have a buffer for errors or unexpected power consumption spikes.
