True. It's been about 5 years since I built a new computer and so my information apparently is a little but outdated, but a quick search through newegg's cheapest power supplies shows things like this:
650 watt, no-name non-80+ power supply for $40. That's the sort of thing I'm talking about. There are 80+ rated power supplies in the same price range or 80+ from reputable companies for $10 more but it's still a thing worth looking for when you're a newish builder or if you have any concern for the overall efficiency of your computer.
After all, base 80+ rating still means that for every watt your PC actually gets to use you're converting .2 watts directly into heat. That's not a big deal for a workstation that may only draw 100 watts under load but if you have a beefy PC with 3090s and an overclocked 12 series i9 processor with a lot of fans, you could be burning 100 watts or more just to power the thing, so it would definitely be worth it to go for gold or platinum 80+ rating just to save the money in waste heat and in cooling that waste heat after the fact.
