Depends, do you like your PC sounding like an airplane from all the fans spinning up?

Nope, the triple fan setup in a big case is fine - if anything, the 3xxx gen cards are quieter than previous ones.

Running games that put my GPU (rtx 3080) usage at 90-100% doesn't even make my PC audible when having (open back) headphones on with ingame sound a normal levels. If you invest in good components and focus on quietness you can get great performance without much noise. In my case, without any watercooling.

With watercooling and a big rad, it can get even quieter.

imo people get a bit too worked up over the peak power draw of parts that are going to be fully loaded only a couple hours per day.

the bigger issue is where all that additional heat is going and how. I'll be paying close attention to the SPL metrics for this generation.

What is SPL? "Sound Pressure Level"? Of the cooling fan?

yes, there are limits to how much heat can be removed by a dual-slot blower without making it extremely loud. open coolers can do a bit better, with the trade-off that they dump most of the heat inside your chassis rather than out the back.

If you're on 110V you should care about the current limits

I have bigger things to worry about personally as far as my energy consumption is concerned, but the main way this impacts me is that my wife and I probably need to get some electrical work done in order to support our devices being in the same room. Our two gaming computer towers theoretically have a maximum combined power draw of 1800 Watts, which is well above the 1450 W which I think is the maximum sustained (not burst) load for a 15 A residential circuit in the US. This is ignoring the few hundred extra watts for monitors, speakers, laptops, and a couple lamps.

Your 15A circuit will support 15A * 125V = 1875W

My understanding is that the maximum should only be used for short periods of time, like for microwaves and hair dryers, rather than for sustained loads like a heater or computer. I think sustained loads are supposed to be 80% of the maximum load the breaker can handle.

Some people might need to upgrade the PSU
