thinking of a upgrade later on though, so want to safe guard this by going 650watt650W is fine, the rtx3090 has a 350W tdp, gpu manufacturers always spec the required psu way above what is required to cover their asses.
You say you have a 6gb gpu which means a gtx1060 for which a 450W psu would be plenty.
