There is more than one way to buy "affordable" hardware. You can buy new budget hardware or you can buy older used hardware. Imagine someone trying to decide between a new 2060 or a used 1080. The 1080 is actually faster in almost all cases. If someone buys a 3080 or 3090 a few years from now, used, it's not going to use any less power than it does today. All these mining cards will get dumped on the market eventually, and it will be an affordable hardware Christmas. But if you want to limit your options, again, more power to you. Not sure how many posts you need to make here claiming that your limited budget makes you prescient about the power consumption of future hardware.
I was just letting the other guy know the sucks thing was just a joke and I'm also using 550W. Not sure why you need to make so many posts shitting on other people's choices.
