AC wattage is voltage times amps times the power factor.
Most of the decent PSUs people should be using for mining have 99% PF

No, I forgot to read that article I linked, but I found another that you might like.
I'm done.

Wattage is volts times amps
that 80% rule is for continuous draw... the breaker trips at the %100 value
Go back to school please

DC wattage is voltage times amps.
AC wattage is voltage times amps times the power factor.
The 80% thing is a design rule that an electrician has to follow if he wants the wiring to pass inspection.
The 80% rule has nothing to do with electricians or passing inspection
that is the design of a circuit breaker
electricians have rules as to wire size ... number of fixtures/outlets ... size of breakers
they must follow
yes ac wattage includes PF .. do you have any clue what power factor is
No, I have a bigger dick

Minor heads up, most 15A circuits aren't able to pull an 1800w load. 15A is not the continuous load that the wiring and cb are rated for. 12A is...meaning you get 1440 watts max on a continuous load.
Wtf?
If this was true, houses would burn down and need to be rebuilt every couple of months. Eventually, people would figure out the problem and start putting 12 amp breakers in, or wiring capable of actually handling 15 amps. Oh, wait, we picked option 2 decades ago.
Watts isn't a meaningful term for talking about AC circuits, except that it is usually sorta close. The real amount of power that a circuit can deliver is measured in Volt-Amps. A 15 amp circuit can handle 1800 VA nominally, but if your voltage it is amperage that trips the breaker, not power, so if your voltage is low, you won't get as much power.

16A, or 1920 watts...basically 80% of the trip rating of the breaker.

What about the 20A circuits?

Keep the Fire Dept number handy.
If you can plug something into your stove, do it.
I'm sorry but some of these threads make me LOL I am in apartment with two 100amp breakers linked together (the two breaker move together).
Found that all rooms are wired to those two breakers.
Separate circuits exist for AC and heating.
So, I should have 200amp x 120v = 24KWatt.
Here is something that gets interesting.
The voltage reading is 122-123V without any mining rig plugged in.
When I turn on all my rigs, which I estimate to consume about 2500W, the voltage drops significantly to 113V.
I think this is unacceptable, as the breakers are rated at 24,000watt max, how can the voltage drop so much with just 2500W power draw?

Voltage is directly proportional to resistance (of your wiring, which never changes) and the current going through the wires (which increases significantly when you turn on your rigs)
2500 watts is 20 amps at 120v.. that's a good chunk.
Also, your whole apartment being run off of two breakers is unsafe and probably illegal.
when you become an electrician let us know
he propably means the main brakers
and 100 amp service per apt is normal
outlets normally have 20amp breakers
lighting 15amp
stove/ dryer 30-50amp
just put half on each of two outlet breakers
and btw most plugs in the wall are not rated for 20amps that can amount to some of the voltage drop you are seeing if your pluging everything in one wall plug
Sorry, I guess the 'Found that all rooms are wired to those two breakers.' threw me off, douche.

Seriously...
How many rigs do you have...
If you can afford that many rigs...
You should not live in tiny appartment...
Put some in kitchen...
some in bathroom...
Turn them off when you need to use oven...
Or anything else that draws a lot of power...
Or sell some...
Or get bigger appartment...
Or get a generator...

Get a test light or a multimeter, learn how to use it, then flip breakers one at a time and test outlets to see which ones are now off. Then draw yourself a map of which outlets are connected to which breaker. Once you have that, connect your computers to different circuits (on different breakers) and you shouldn't have any issues.
