Question / Help Is 600w psu good enough for this setup when streaming 720/1080p?

[Dontjudge]

Hello everyone, i am planning on buying a new GPU for my pc. I am currently streaming on 720p with the following setup:
16gb RAM
Ryzen 7 1700x
GTX 1050ti.
My PSU is LCPower 600w.
Mobo: Asus Prime A320m-k
My question is, will this PSU be able to handle a Gigabyte GeForce RTX 2060 Mini ITX OC 6GB while streaming on 720p or even 1080?
I've been told that a 600w PSU is a sweet spot for this setup, but i'm not sure if it's the same thing while streaming. Thanks in advance!

Depends on the PSU quality (amount of 12V rails and more).
Just from a max. power perspective, it's definitely enough. My old 1700x + Vega56 and my new 3700x + Vega 56 are more power hungry than your setup and while streaming+gaming I usually need 250-350W (depending on the game).

The 1050 Ti has a TDP of 75W. The RTX 2060 has a TDP of 160W. Therefore, your new setup needs 85W more power.

But since a 600W power supply is vastly overpowered for your previous system, it will be enough for your new system.
Even a 500W power supply would be enough for your new system.

I'm not making the numbers up - I designed my machine a few years ago and computed all the TDP values of all the components and ended up with a net requirement of about 400W for a system that contains a CPU with the same TDP as your system, less RAM, and a GPU with the same TDP as a RTX 2060. I rounded up and bought a 500W PSU and made sure the power lanes that come out of the PSU are actually used and not overloaded. So you would be fine with even a 500W PSU.

You know, it's not that the whole 500W can be pulled from any one connector of a PSU. There are multiple lanes with their own circuits that have their own power limit, and it's only 500W because all circuits add up to 500W. If you don't connect some connector, for example because you got a PSU that has double the connectors to connect two GPU cards, you might not be able to use the full power of a PSU if you only connect one GPU. Because of that you don't buy exactly the W-count you know your machine needs, but 50-100W more. But 200W more is a bit excessive. You waste money and energy, since the efficiency of a PSU is less if it is only partially used. The most efficient use of a PSU is at about 80%, as far as I know.

Thanks for a detailed response! Would this PSU be fine even on stream with 1080p settings?
