PSU Upgrade

[Cooners]

I've (hopefully) got a 5080 coming tomorrow but in all the choas I kinda forgot I only have a 650W PSU. Can anyone recommend a good new PSU (I think 850W will be enough) without going mad as I'm going to get murdered for spending so much money as it is.
I have a a 3900X cpu (going to grab a 5700X3D once I sell my old GPU) on a X570 mobo, a few fans and a couple of NVME's (no HDD's as they are all in my NAS).

What model is your 650? If it is a good one you'd likely get away with it, especially if you tweak the power usage.

Asus TUF Gold has been on offer a lot lately. At the higher end, maybe Antec's HCG Pro which is derived from a Seaonic Vertex.

It's a Seasonic core gold 650W psu
