Power supply comparison.

I am getting a GIGABYTE X570 AORUS Master with a Ryzen 9 3950X and a AMD Radeon RX 5700 XT or a
Nvidia GeForce RTX 2070 Super and I am looking at theise units brands what do you like best.

All of those models are outstanding products and you should not experience issues with any of them. If you find one of them on sale, that's the one you want.

As blay said, all are top-notch (outside of the original supernova) and you cannot go wrong.

As far as wattage, there is no need to go over 750W with your listed specs including heavy overclocking. You can easily use a 650W model for just about any single CPU and GPU setup and still have adequate headroom for overclocking and silent operations.

what^^^^^^^^ those guys said.
Just make sure that the one you choose has all the connectors you need native to the unit and the cables are long enough for your needs.

Pretty sure the OP could get away with a quality 550 watt PSU. I've had no problems with mine.

more than likely, yes. But even I prefer a bit more headroom for overclocking and quiet operation.

 

[Alaric]

Quiet is good. I don't have a headroom problem with my PSU, most of (if not all?) my limits are mobo related. My RAM tops out right where Gigabyte says it should, and I've seen a lot of Skylakes go over 4.7 GHz.

Not sure of your point here in is regards to overclocking limits... a PSU has little to do with what it can achieve. So long as the PSU has enough power, using one with more wattage doesn't increase the overclock or clock things where 'so and so says it should'.

You also have a 6700K (91W stock), and a GTX 1070 HOF (150W). Let's assume 130W and 200W for overclocking... there is 330W... another 50-75W for the board, etc... and yeah, makes sense for you. Remember the OP has a 3950x (~140W all core load @ stock), and a 5700 XT (225W, reference/stock). If he is stock, absolutely. Otherwise, it can get close and why I said 650W in order to maintain quiet operations.

 

[Alaric]

True. I don't know why I assumed "newer chip=lower power". That's a lot of cores.
