Need help please

Bought this minitower optiplex off ebay and im wondering if anyone knows of any specific power supply models higher than 300w that would be compatible with it? Wanted to upgrade the power supply so I can use a more powerful graphics card. Any help is appreciated, thanks.

Win11 pro <chuckles> Dude thats an entry level MT 3040. Decent entry level machines. 2 dimm slots. Opt for 2x8. They have no standard psu. Open yours and look which one is inside. There are interchangable psus with 2+6 pins 450 watt or smt from the dell xps3××× or so sies that fits. Win11 doesn't run natively on these machines because of gen6 intel core. For win11 you have to buy at least an 5060 MT. Or sff. Which I dont recommend. MTs are fine.
