If the goal is to get as efficient system as possible, that is noble, saves you electric bill and green for the planet.
But platinum and gold start differ only in certain ranges of use. What is typical wattage range your pc operates?
For example I have a EVGA 210-GQ-0650-V1 (650W 80+ Gold) I got in 2019. It would be nice to plug in my specs and compare to other PSU to see what the wattage differences would be from the wall.
Best investment.
You need to know what is your PC uses (advise: invest in kill-a-watt or similar meter for 20$ and just measure).
Let’s say you game on your PC 3 hr a day, and it uses 400W. Other time PC is off.
Look at the efficiency curve of the PSU (they provide it with the specs). A Platinum is 92% efficient at 400W, this Gold model is 91% at 400W. 1% difference = 4Watt. 4W x 3hr x 365 days = 4380 Watt-hours you will save per year with Platinum compared to this Gold. At 0.15$ per kWhr 4.38x0.15 = 0.65$
65 cent a year in savings - i doubt it is worth the price premium of Platinum over Gold.
Now, assume your other PC uses 700W 24/7.
At 700W, platinum is still 92% while Gold is 88%. 4% of 700W is 28Watt. 28W x 24hr x 365days = 245280 or 245 kWh that the Platinum will save you in that scenario. 245 x 0.15$ = 36$ a year. If Platinum cost 100$ more than a Gold, you will earn this price difference back in 3 years. For that scenario it definetly makes sense to consider Platinum - it will pay itself back.
Now this is just an example, use your own data in calculations, it is very simple.
