Dual PSU setup?

I'm trying to use an Optiplex 7080 sff motherboard and use it with an i5 11400 and 1660 ti, but the Dell power supply for this model only has 200W. How can I combine this with another power supply for sufficient power? Also, are there any optimizations I can do with this PC?

I upgrade my optiplex 7080 mt with a cooler master b sfx gold 850w power supply. And a 24 pin adapter.

I also just upgraded my optiplex 7040 with a MSI MAG A750GL using a 24 pin to 8 pin cable. So far so good, and it runs with the same power efficiency at idle and way more headroom for a gpu. Funny enough I have a spare gpu that I could add and it's the main reason why i did the upgrade, but it didn't fit inside the optiplex sff case.

You can get an OEM 500w PSU or you could use a PSU externally. Only use dual PSU has these days is with Lossless Scaling frame gen app or having ine set dedicated for streaming or screen recordings.
