At ~310 estimated usage you’d probably want at least a 450 to be safe I think.
With only 350 you’d probably need to undervolt or set power limits, which beyond obviously limiting performance (but at least something the Steam Machine suffers from too) isn’t exactly “it just works.”

another thing is that PSUs slowly lose capacity over time. eventually the system might turn really unstable and eventually unusable.
