Hi, I'm currently looking into upgrading my GPU and I don't understand what psu I should get next to it. I'm changing my GTX 970(145W) to a asus strix 2080 super (250W) and currently I have a 550W psu, does this mean I need to get a 650W one?
My other specs if it matters:
I7-6700
16GB of DDR5
Asrock B250M Pro4

yes a new unit. a quality 550 or larger. the new CX are much better than the unit you have, look for the grey label.
15W, is not enough overhead on such an old platform the unit will be running at or near max and that is assuming you had 430W to start with that is a 336W unit.

I made a huge mistake, I looked at a wrong box and I don't have 550W but this
Corsair 430W CX430 CP-9020046 EU
Sadly I might not be right with this one either, but what I know is that my current computer was assembled by professionals so this plus 100W of usage should make me get a new PSU, so what do you recommend?

So something like this:
Corsair CX Series CX550M 550W Bronze (CP-9020102)
