Question nvidia 1650

[sanumax2]

I am looking to buy a new graphic card to replace my earlier amd 7850.since buying a new smps will cost more than 5k lookng at options that can work in current setup normal 1650 doesnt require smps.In Amazon only the 1650 overclock versions are available .its on sale today. In card review it’s written that overclocked card requires smps and wont run on only power from motherboard.is it true?
will then running with my smps will be risky ?

also my motherboard shows pci 2.0 compaitable while card shows 3.0.

does it matter?

hoping someone can clarify these too?

You seem to be overthinking this. Whether the GPU is getting power from only the motherboard, or the motherboard and the PSU, it's the same 12V power. It should run fine.

PCIE 3.0 GPUs will work with PCIE 2.0 motherboards. Only the very high-end GPUs will notice any performance loss.
