I just got a Ryzen 5800X and a new mobo, and my current PSU (Supernova G3 650W) does not have an extra CPU header to satisfy this new mobo's demands (It's an 8 + 4 pin CPU header). PC part picker estimates my new wattage will be ~ 410W, and I do intend to do an amateur overclock. Right now the two PSUs I'm looking at are on sale. G+ 650W and MSI 750W.
Do I a) go with the G+, b) go with the MSI PSU (+100W, but more expensive), or c) there's magic I can do with my existing cables.
I should mention that I am using both VGA cables to power a 2070 in case some magic could be done there.
