PSU questions

I have been googling a lot trying to find a answer and its kind of hit and miss.

The short: I have a new/used pc with a PIA Asrock x99 extreme 3 Motherboard, i75930, 32gb ram, gpu 1050ti, gpu radeon r9 2070x.

Currently everything works with a 750psu, but I know I am at the limit and want to add more HD's/ssd's

I am going to add a second 1000w PSU for the Gpu's only, and power everything else with with the 750w.

I have a 24 connector cable thing for the two PSU's, so everything will power on well. Do not really want to change the 750w psu from the motherboard because asrock is so touchy.

Am I crazy doing this? or open to better suggestions.
