Adjuster, you need to check out the AMD Ryzen CPU thread that is a few threads below this one, and follow Pudgie's build
yes a good seasonic 650 watt PSU as obeo posted... and me personally will never bother with another MSI board again, having had 4 to 5 of them fail, due to pour Quality Control
Do more research on this before you pull the Trigger and buy the wrong stuff
hope this helps
TC
edit: Pudgie, if you got time and see this, please help Adjuster out on what he needs for a good quality component build, I personally don't like most of what he has posted on his list for an AMD build, and he did not even include a CPU heatsink/cooler....
