@realimad12,
Are those the only two video cards you want to upgrade to ? Between those 2 GPUs, I would recommend going for the
GTX 1650, if you don't have the budget to upgrade to a more powerful GPU. It's more power efficient, and the minimum PSU required is 300 Watts. That's what Nvidia claims on their website though.
Even though some of the 1650 models GTX 1650 do not require any additional power connector, and its power draw is rated at 75 W maximum, few TECH sites are mentioning a 350~400 Watt power supply unit, as the minimum.
I think some AIB custom GPUs
might require a SINGLE 6-PIN PCI-e cable though, but I'm not fully sure. But I checked TechPowerUp's database, and some models do require a 6-PIN connector..
