Will it work with RTX 4000 16-pin connector?

Yes it will. Look on corsairs website, they have the adapters their you can order for this psu, or you can order one from cablemods or somewhere else that makes cables for psus.

If I order now, will you take the money now or when will the goods be?

I ordered 2/14, hasn't shipped yet as of 03/07.

What are the dimensions of this PSU? and how much space in front of the modular connections would you say you needed to plug everything in?

The dimensions are 200mm (7.87 in.) L x 150mm (5.91) W x 86 mm (3.89) H. Not sure about the space in front requirement because I haven't assembled the PC yet.
