Is a 750W PSU Sufficient for a 5070 Ti and 7800X3D?

Not all 750W PSUs are created equal! The Gold certification helps with efficiency, but you also want to confirm the specific model you’re considering. Generally, if it’s from a reputable brand and ranks well on PSU tier lists, you should be fine. But if you're still uncertain, going for a solid 850W option would provide extra peace of mind.

Yes, a 750W PSU should work well with your setup. It's more than enough power for the 5070 Ti and 7800X3D, considering those components typically draw around 400W combined, plus minimal additional power for other system components. Just ensure your PSU is well-rated! You have about 300W of overhead, which is plenty unless you're planning to upgrade to a much more demanding GPU in the future.

Even if you're not planning to upgrade anytime soon, choosing an 850W PSU can be a smarter investment in the long run, especially for a setup like yours. And don’t forget to look for those A or B tier ratings in the PSU tier lists!

You might want to consider a higher wattage PSU if you're looking for some future-proofing. An 850W PSU is typically a safer bet. Plus, it won't cost much more than a good 750W, and it gives you more headroom, especially for future upgrades. Make sure to check the PSU tier lists to ensure you get a reliable one.
