XPS 8300, upgrade MSI GTX 1660?

Hi all,

I've got a family pc which is a XPS 8300, it's had a SSD upgrade and RAM upgraded to 32GB.

I've been trying to find out if it will handle a new graphics card a GTX 1660 from MSI.

Does anyone know if the stock PSU would be enough and if the Motherboard & BIOS would be ok with it?
My son did contact the manufacturer for me, but they told him to go to the PC manufacturer.

Thanks
