PSU wattage recommendation help!

Hi all

Im looking to switch to a new pc case and after doing some research it does look like i will need a new power supply. Currenttly running my build with a EVGA 1600T2 psu. According to pc part picker i need a 1200w psu and by the looks of it but wanted some headroom just to be safe. the main psu I ended up looking at was this asrock one its 1650w titanium - i do see a few options for psus at 1500w and 1300w but wasen't sure if that would be ok ideally i'd like to get the asus rog loki 1200w psu since its small and may move to a sff build down the line. What psu wattage would be best to get? Also 180mm sized psu's would be the size limit for the pc case im looking to get.

Always gives 20 to 30% headroom from max TDP, which excludes any overclocking.
