I got a pc with Ryzen 5 4650g without a GPU and the case came with this PSU:



This is the case http://www.gtt-cn.com/product-info.php?ptid=1315, and I don't think there's any more info on this PSU. I won't be using a GPU (though I intend to game) and I calculated my load wattage to be 134W, at first I thought I'll change the PSU if I decide to add a GPU, but after reading about PSUs, I wonder if it's safe to use, or I shouldn't risk and change it sooner?
 
With a GPU that's listed as recommended for a game I'd play, I get a recommended wattage of ~370W and I wonder if I should choose a 400, 450 or 500W supply, or more? Should I have a starting point price? So far I looked for 80+, active PFC, at least a 6 pin PCIe, and 5 protection types. These are the cheaper ones, ~20-30 euro:

Also I was checking 80+ certifications here (I'm in EU so I believe it's 230V EU internal?). The cheapest ones from Seasonic and EVGA for ~50 euro are https://seasonic.com/s12iii and https://www.evga.com/products/product.aspx?pn=100-W1-0500-KR, they're also marked as 80+ but I can't find them in said website and Seasonic doesn't even appear, but maybe it doesn't matter or I'm doing something wrong?
Of all the units listed, the Seasonic looks the best - note that 80+ isn't the same as 80+ Bronze certification (with Silver, Gold and Platinum being higher than that) - I would go for the Bronze unit. 50 Euro sounds like a sensible price point, if you are looking at less than that they usually cut corners on basic components.

In terms of power required - personally I would always go for 500W for any build as it gives you head room to add to the system later (extra drives, a faster processor or add a graphics card). That would be enough for pretty much any cpu at stock clocks and should handle mid tier graphics cards fine (probably up to an RTX 3060).

That looks to be a pretty cheap unit - it will probably work with a 4650g as that apu doesn't use much power but honestly you are probably better off replacing it with something better for long term use.
