I strongly disagree.
Counter argument, if you need one: there are motherboards of the same age out there and requirements for the power quality VRMs produce for the CPU are much higher — and yet, they work for ages just fine.
Do capacitors age out, esr drift, capacitance change? Yes. Does it matter? No.
You can remove 80% of those capacitors from the PSU and it will continue working as if nothing happened. Most of that capacitance is for EMC compatibility, power factor corrections, and other irrelevant for most people needs. Those that are revenant — are driven by regulation with negative feedback. Even if envelope exceeded — 5 and 12V rails are not picky to power quality. The picky ones are served by just as aged out VRM on the motherboard.
So no, that objection is not valid.
And on the 2kw PSU which is happened to be first result — don’t buy it obviously if your power consumption is not 200W. I bought 960W one. Works as advertised. I also bought old motherboard with capacitors, old backplane with capacitors, or CPU with capacitors, and wait until you learn under what environmental conditions do capacitors in the ECU in my car work for past two decades.
The reason for the pricing has absolutely nothing to do with their viability.
