PSU recommendations.

Thinking of upgrading my current Silverstone SST-SX650-G SFX 650W 80 Plus Gold Modular Power Supply to accommodate a possible CPU upgrade, I currently have a AMD 2600X and a 3070/80 GPU.
What do you suggest or am I fine with what I have?

If its going in the case in your sig, then no. I'd keep it. Silverstone make pretty good SFX PSU's & you'd have to pay a fair bit of cash to get a better one, at least 3 figures.

650w should be fine for a 3070 and 2600X.
Might be pushing it on a 3080 though if your planning to overclock.

- But if you are in any doubt just buy a cheap inline watt meter and see what your pulling under various gaming loads from the wall (that's what I do).
As long as your about 100w off the maximum limit of your PSU rating your good.

Cheers mate, my limited research suggested the same.

I have one of those somewhere will see if I can find it. Thanks.

With lack of VRM quality in board of your sig I would suggest staying in 65W TDP CPUs.
Or at least making sure case cooling is good.
