[SOLVED] PSU required for graphics card upgrade

[Gro10]

My son has brought the following system for gaming. PALICOMP Gaming PC INTEL Coffee Lake Core i7 8700 3.2Ghz - 4.6Ghz Turbo 6 Core - 16GB DDR4 2133Mhz RAM - 1TB Sata3 HDD - NO OS - INTEL HD Graphics - C
ASIN: B07B53BBH4
Unfortunately it's not as good as he thought (graphics card).
He has just brought the geforce gtx 1660 super graphics card to replace the onboard one, but needs to know what size PSU he would need. I haven't a clue I'm afraid and would really appreciate help. He plays fortnight and has a 144hz monitor, connected through Xbox and elgato? and streams aswell. Many thanks in advance. Glyn
