Whats going on guys

my 480s take my Strider 1500 to the limit so I want to run 2x Antec 1200 with dual psu 24 pin adapter.
What is the best way to connect everything safely?
PSU 1
2x 8pin for cpu
24pin to mobo
2x 480 (2x 8pin & 2x 6pin)

PSU 2 with adapter to mobo
PCIe Molex 4 pin
2x 480 (2x 8pin & 2x 6pin)
