Nvidia suggests a 350-400W PSU for the GTX 1650. However different manufacturers have their own standards when it comes to setting the minimum wattage but the difference usually isn't that much. 350W should theoretically work if you don't have any other power hungry components in your tower (Aftermarket coolers etc) then it should be okay as the PSU you mentioned seems to have a 6pin PCI connector as well.
You don't necessarily have to go with a low profile model but it does have the benefits JasoNs__ mentioned. But the 1650 isn't that power hungry of a card so you should be able to go with a standard one.
As for heat, a exhaust fan should be good enough, but I would suggest adding an intake fan to the front (if the case has the option for it) or any other place that an intake fan could be mounted. 1650 isn't really a toaster when it comes to heat management but an intake fan goes a long way.
I wouldn't worry too much about it. But do consider upgrading that PSU sooner than later, it's kinda pushing it at this point.
