New Build, What Size PSU

[captkirk]

Greetings

It's been awhile since I've posted on these forums and would like opinions on what size PSU I should use. The build will look something like this.

Corsair Obsidian 450D case
Rysen 7 1800x processor
Asrock X370 Taichi motherboard
Corsair Hydro Series H115i water cooling
Corsair Dominator Platinum DDR4-3200 ( 16GB)
Asus Strix Radeon RX-580 (8 GB)
Sound Blaster AE-5 sound card
Samsung SSD 850 Evo 1TB (3x)

That's pretty much it. I apologize if I've left something out. I was considering a 1000w psu, but am wondering if I could manage with an 850w psu?

Just thought I'd stop by and let you know that I decided to go with the 1000w PSU. I remembered that the old adage "more is always better than not enough."

While more certainly doesn't hurt, I think the days of 1000W PSU (even 850W) are numbered. CPUs are not as power hungry, and neither are GPUs. On top of that, multi-GPU setups are less and less supported, and that greatly reduces the need for large PSUs.

As to a PSU calculator, I've used eXtreme PSU Calculator in the past: https://outervision.com/power-supply-calculator

But you can probably use one from a reliable manufacturer:

MSi: https://www.msi.com/power-supply-calculator/


IMHO, a 650W PSU is probably more than what most people will need going forward.

Have fun with your new build. When you're done, be sure to post some pics - I love seeing what other people are building. And if you run into some roadblocks you overcome, be sure to discuss those, too. Hopefully, it will help someone else later on.

The for the reply, btdog. I will do my best to take some pictures of my new build.
