Question Will 550w PSU be sufficient for 3900x x570 5700xt and... ?

[raydeon]

trying to put together a new build (last one was 2500k in 2011). I am looking at getting at least the following: 3900x , x570 mobo (aorus elite), 5700xt, and of course, rams, couple of my old SSDs and a new m.2 pcie nvme ssd.

there is this EVGA 550w PSU from my old system that runs perfectly fine. can i get away with it? or i need more juice to power the new techs?

thx !!

Replace it, it's 8 years old now.

And a good quality 650W would be better.

Wants all new parts except PSU. People have an interesting mind set about power supplies.

"Can't bench mark it -- Can't be better."

"Still works -- Must be fine."

You know how it is.

People telling people things like that and this:

"I still have PSU's that I have been using for 20 years"

"PSU's last forever"

And so on with other very bad advice.....

You didn't say that. You said your build was from 2011 and that your "old system" (which we assumed was the 2011 build) had an EVGA 550W.

For the record: "BRONZE" is not a model name. EVGA has a varying range of Bronze products from crappy to great. And each one has a model name. Please refrain from calling a PSU "BRONZE" just because it has Bronze efficiency.

Looks like I got even the bronze part wrong lol. Here, it's a EVGA SuperNOVA 550 G3 550W 80 Plus Gold Modular Power Supply.

Thanks a lot for helping!

The G3 is still pretty new so you should be fine.

That's a pretty significant difference from your first post.

Kudos. Use the G3. You're fine.
