Upgrading a Dell 3030 Power supply to ATX (need compatible ATX connector)

I'm trying to upgrade the power supply on my 3030 Dell Inspiron to run a 5060 ti graphics card. The power supply I have is a 750W ATX power supply that will be external. What connectors are compatible with the 8 pin 3030 connector? Optiplex 3020, 7020 9020?I'm looking at the following connector on Amazon.

OP can not use the Amazon 8 pin adapter.  that adapter for was for old Inspiron 3650 and Optiplex 7040/9020.

user had validated Dell oem 500w psu for Inspiron 3910 which has same pinout as 3030.
