Am I going wrong with a 550W PSU for this build?

Obbama

For my build which kind of PSU should I get? 
I'm about to buy Seasonic Focus Plus Gold 550W Full Modular (since its at a discounted price at my local shop), would 550W be enough for my build or would I be better with a 650W one? Thank you!

550 is fine

 

tho there have been some problems with seasonic the last while, but that only really applies to the v64 and 2080 ti

What does PCPartPicker tell you when you load up those parts?  It does have an estimated full-watt draw calculator built in when you make a build.  It's likely saying something barely over 300W for that.  You're fine.

edit: put it in partpicker, I was that close, neat.

That's a good choice for the PSU.

 

But what about the motherboard choice? I wouldn't go with that B450-A board with a Ryzen 7 2700X because of the rather weak VRM-s.

550W is absolutely plenty, but the Focus is known to have issues with some GPUs. Might want to check out some other options

It looks like it was limited to an ASUS GTX 970 Strix, and Vega 56/64, so with an RTX 2060 he's likely fine.  It was limited to few GPUs and shielded PCIe power cables fixed it for those that did have it.  No reason to spread FUD about buying an otherwise perfectly good PSU (when GPU's ripple stays in spec and doesn't exceed standards)

It is confirmed to have issues with those GPUs. That doesn't mean it's guaranteed to work with all the others. And if there are other options that don't have that issue, but are otherwise equal, why get the Focus?
