PIGLINE

Hey all! I'm moving soon, and am planning on starting from scratch with my network at the new place. Currently I'm using an ancient modem/router combo that I should've ditched a while ago. I want to make sure I'm not missing anything or going overkill for my needs, and ask for general advice I may have missed in my own research.

We're moving to a townhouse that has a small footprint, but three levels: basement, main floor, upper floor. The basement is going to be used as our living room, and the upper floor has the bedrooms and office. There are three of us living together, and I'd say typical internet usage for us would be a 4k streaming connection, a 1080p stream, two gaming connections,

I've got a 650w G+ PSU in my build, and I was looking for new cables to get for it. All I'm seeing is options for the G2/G3/etc, but no G+. Do they share the same pinout? I know the G+ is a refinement of the G1, and I've seen a few people say they should be comparable, but I wanted to make sure before spending the money, and potentially shorting my system if I get something incompatible.
