Computer PSUs do not have a transformer input- they have a rectifier/ capacitor input which has quite different inrush characteristics to the OPs circuit.
I would say most PSUs today are switchers and have no mains transformer.
I have several DELL laptops powered by external brick-type PSUs and they have no inrush protection and will blow fuses and trip breakers like crazy. About a year ago, in a hotel in London, it blew the fuse of the plug/adapter and I had to repair the fuse with a strand of wire. All this with no tools to speak of.
So now all my bricks are fitted with a cord which is as thin as I can get it. This adds a certain resistance and the heat is dissipated away from the PSU. This is a very good way of limiting inrush current and also even out the spikes of current which go through the diodes in normal use. And a very light cable is a plus when traveling.
I also add a NTC in the cable itself. It looks like a tiny wart.
So I solve the inrush problem without even touching the PSU itself, only by replacing the main power cable.
Yes, it is amazing the components you can get from junk, and computer PSUs are a rich source. One of my favorite sources of components are the bases of failed EL ceiling lights: capacitors solid and electrolytic, transistors, inverter transformer.
I have crates and crates of electronic junk which I use as source for simple basic components. A basic line filter and inrush limiter is something I would not even consider designing or buying as I can get it from my junk pile. Heat sinks, diodes, transistors, caps, etc.
And when I feel like killing some time and relieving some stress I will spend a while removing components from boards. Sometimes slowly and carefully with a soldering iron. Sometimes I will hold a board over an open flame and remove the components much faster.
I have crates with dozens of transformers and have built countless linear power supplies pretty much with recycled junk.
I really need to stop collecting junk.
