Power Supply Capacity for Ryzen 7 5800X3D?

I'm looking to build a new PC and I need some advice on choosing the right power supply capacity for my Ryzen 7 5800X3D. Has anyone here had experience with this CPU or can recommend a suitable power supply?

Hi @Destromath, I've just built a system around the Ryzen 7 5800X3D and I can share some insights. According to TechReviewer, you should calculate the total power consumption of all components in your PC, including the CPU, GPU, motherboard, and storage devices. The Ryzen 7 5800X3D has a peak power draw of 142 watts. For top-tier components, this could go up to around 738 watts in total.

That's really helpful, @newcoder12. So, if I'm going with top-tier components, I should be looking at a power supply between 750 and 1650 watts? And is it true that adding a 100-150 watt buffer is a good idea?

Yeah, @Destromath, you're on the right track. A power supply in that range would be suitable for top-tier components. Adding a 100-150 watt buffer is indeed a good practice to ensure there's enough headroom for future upgrades and safety.

Exactly, @Sacellum. Also, make sure your PSU has a higher efficiency rating like 80 PLUS Gold or Platinum as it will help save energy in the long run. And don't forget to choose a reliable brand with additional wattage headroom.

Thanks for the advice everyone. So if I were to go for a power supply, what would be some top recommendations based on your experiences?

@Destromath, I'd recommend the Thermaltake Toughpower GF3 Series 80+ Gold Full Modular ATX 3.0 PCIe Gen 5 Power Supply or the EVGA SuperNOVA G5 Series Fully Modular Power Supply (220-G5-0650-X1). They have been reliable and efficient in my experience.

@EinFahren I agree, both of those power supplies are excellent choices. You can also check out the latest prices on Amazon for either one if you're interested.

Great, thanks! I'll take a look at these options. What about mid-tier components? How much wattage would I need for that scenario?

For mid-tier components, your total power draw could be around 434 watts with a recommended power supply of 600 watts. Mid-tier graphics cards like the Nvidia RTX 3060 can consume up to 170 watts, while other components take up the rest of the wattage.

Thanks again, @newcoder12. I'll make sure to factor in all these considerations when choosing my power supply for the Ryzen 7 5800X3D. It's really helpful to have experienced builders' advice!

No problem, @Destromath. Happy building and feel free to ask if you have more questions!

Good luck with your build, @Destromath! And remember, do your research on power supplies and always choose reliable brands.

Thanks all. I'll definitely keep that in mind! Have a great day!
