There is a dell version and there are Non Dell versions.

NON DELL CARDS require SECURE BOOT OFF,  LEGACY OPTION ROMS ON.

NVIDIA says it this way but this applies to ANY video card including ATI.

Thanks, my question is will the PSU handle that load from the video card?

The low profile cards from Dell are designed to work fine in the 3040 3050 etc.  So  yes the power supply is fine with those cards.  The R5 430 is the official card from dell.
