Vostro 3470: how to upgrade the 200w power supply?
I bought a Vostro 3470, i5-9400, 8GB Ram, 256 SSD. It comes with a power supply of only 200w, which is very low and doesn't let me even think of upgrading the machine with a decent video card (GPU). I would like to know if there is any other power supply with a bigger wattage (best would be at least 300w, but from 240w on it's already fine) compatible with this tiny version of PC.
Thank you!!

I actually found a PSU which fits dimensionally. It is a 275w 24 PSU which can be found here. The only thing i would have to do is to buy the adapter you hinted, and that's it. What do you think? I will keep looking for a 300w one, but this 275w seems to solve the problem (at least 75w gain from 200 in a very efficient setting as the 3470 SFF seems enough to me).

Totally proprietary no upgrades. Power connectors totally proprietary.
3650 is shown for reference but the 3470 uses 6 pin not 8 pin power

The power supply is a stick its not even full size.
removing the internal power supply and using a moddiy 24 to 6 pin adapter might work with EPS12v PFC power supply.
You run the wires thru the hole left behind by the removed power supply.
YMMV however as I don't own this model and never will.
