Marketing propaganda by big tech companies has brainwashed a majority of users. There are tons of 850W and 1000W power supplies, as if that were normal.
The truth is, 90% of PC users never ever need more than 650W. And that’s still generous. Not only that, it gets even better! Most of the time, it’s even worse to get a PSU with a too high wattage, because of efficiency problems and unnecessary higher power consumption leading to higher PC running costs, without any reason but corporate propaganda.
If you run a normal PC with medium specs, it’s perfectly fine to run with 450W to 550W PSUs. There is even enough overhead in those. If you want to be extra safe and have extra room, you can go for 650W or maximum 750W. But even that is too much.
Nobody needs 850W or more, except they are running some huge setup with a million LEDs, 20 HDDs, 2 graphics card, etc. Then you actually need those 850W. If you just run a fairly normal PC, even with a fairly new graphics card, you will never ever need more than 650W.
The only way you are really in need of 1000W or more is when you are running 3 graphics cards and a huge RGB lightshow. Otherwise, every PC user is far away from that need. As described above, the case is very similar to 850W supplies. You just need to substract a graphics card from that example setup.
I know someone who runs a low mid-spec PC on a cheap 200W power supply and it never had power problems.
