Corsair has been in the gaming space for a while now and it is a company that I trust. The Corsair RM750x is a great power supply for the Nvidia RTX 3070 and even the RTX 3080 if you are not running an extremely power-hungry CPU.
This is an 80 Plus Gold power supply so you are going to get that efficiency and reliability. This is also a fully modular power supply unit so cable management is going to be much easier as you are only going to use the cables that you need. The others can be kept in the box and packed away.
While this is not a PSU for extreme power users. It does get the job done and keeps silent when doing its job. For the price this is a great PSU that we can recommend for the RTX 3070 and 3080.

This is another 650W PSU but this one costs lower and is available right now at a discounted price. It has a 60 Plus Bronze rater and is semi-modular which means that you are going to have to deal with the basic cables but then again you are going to use them anyways.
While it is not as cool as a Gold rating or being fully modular but then against, it does not cost as much either. This is an affordable and silent PSU that we can recommend for the RTX 3070 and even 3080 depending on your CPU.
The EVGA Super Nova 750 Ga is ideal for all the Nvidia RTX 30 series graphics cards but for the 3090 you should definitely check the CPU that you are using and how much power the GPU and CPU combo is going to use when under load.
The EVGA Super Nova 750 Ga is a fully modular power supply with 80 Plus Gold rating. It has an eco mode for when the system is not using a lot of power. It comes in a sleek black color scheme and should blend in well with the rest of your build.
