Is 550 watt power supply good enough?

550 Watt PSU enough?

I want to upgrade my GPU from a rtx 2060 super to a rx 6700 xt in this summer, but i heard you should have a 650 watt psu, what do you mean? Is this a risk if i try it with my thermaltake 550 watt psu?

I’m pretty much gonna upgrade my entire pc next month and I’m now wondering if my current PSU is good enough for the new setup (according to

i9-9900k cpu
Freezer 34 esports duo cpu cooler
Nvidia rtx 3070 gpu
4x DDR4 8gb RAM
Gigabyte z390 aorus pro motherboard
Samsung PCIe 512gb SSD
3x 120mm rgb fans
And then a bunch of USB’s such as gaming mouse and keyboard, webcam, speakers, headset and then my monitor which is a 35” LED using a display port cable.

I don’t know how much of that info you really needed but I thought I’d include all of it just in case.

Thanks in advance

The current PSU is 550W max.

It's Very risky here. There are people running 700watt PSU getting crashes on a 3080 , and it wasn't until they get a bigger 850 or 1000 that the problem goes away. If you input your config into one of those PSU calculator such as
Do a Google for Ampere power requirement. At the end of the day. you're building a new system, 750watt PSU it's not a lot of money for a bit of assurance is it? you need to consider future proofing as well as efficiency , a PSU Running full capacity is never efficient. a 50-60% draw is the best.
if you buy something >750watt, you should be able to keep it for your next upgrade, Think about the time and stress you'd go through if the 550 is crashing your system.

If you input your config into one of those PSU calculator such as https://seasonic.com/wattage-calculator , you're drawing about 500watt and Seasonic recommends a 650 PSU. When you load a 550 watt PSU with that much load, the power isn't gonna be stable and it's gonna run Hot. Nvidia recommends a Min of 750watt.Do a Google for Ampere power requirement.
