Help a noob. Are voltages between an laptop and desktop too different?

In the room there is only one wall plug and i have two long w/triple outlets across the floor to use a tv, tv indoor antenna, heat fan, then on the second long tripe outlet for laptop and for cellphones chargers.
The thing is im thinking into getting a desktop and i know there'll need at least two outlets for the desktop, but as far as i know the wall plug doesn't seem to hold on so many heavy things on if in this case desktop and monitor pull so much v that it might shutdown the eletric board, like it did like one time i tried to connect more things than those listed.

Sorry if i described it wrongly but i'm not tech savvy :/

First thing First, the wall outlets are going to be amp limited. Each breaker could go to many more than one outlet. Atypical home breaker in the US is ~1800W or 15 amps if i remember. You can install 20 amp and even 30 amp fuses but the wiring to the outlets from the breaker needs to be rated up to the fuse limit to be safe.


What this means for you:

the TV, phones, laptop charger, etc are all low amperage devices in the grand scheme of things. However, the heater is going to be an extremely high amperage device. The heater should definitely be separated from the computer on your home circuit.

another thing to consider is that sometimes a large room can have 2 fuses for it. MY basement has 2 fuses basically splitting the 2 halves of the floor space. I have all of my entertainment equipment on one fuse (TV, surround system, 2 12" subs and a computer) and have no problems. But when i turn the heaters on in the winter, they need to be on the other fuse. I know the layout of the fuse box so this is easy for me.


so, one fuse should old everything (desktop monitor TV laptop phones etc.) except the heater. The heater should be put on a separate fuse as it is likely the main contributor to tripping the fuse.


Maybe run an extension cord form another outlet (and make sure its a separate fuse) just for the heater? You might also be surprised how much a desktop can heat a room, maybe you dont need the heater once you get the desktop running :)

Hi there, so i really don't understand the things labeled on the circuit box mean but i can describe to you there is this large box where you can see the consumed kwh and at right this rounded switch that turns off etc where there is a power outage like in storms etc.. then there is the switches at left only three of them (idk if that makes sense since it a 4 rooms + kitchen, bathroom apt ??) at each of those switches it says "250v 400v~" so idk what this means would the entire house support only that or each room..?

But i think it can support a pc because i checked my heater consumption and i was quite shocked that it says 1800w to 2000w, maybe that's why during winter i couldn't turn on 2 of them for long or the power went off on the entire house.
So i think i can turn a pc here, probably i can't use both pc and heater like you said or it will go off.

And yes i already have to use a power strip to plug the things described above, but i already and since ever do that daisy chain thing you pointed out not to de, because it's the only way i can reach the things along this room, since there only 1 wall plug, i have two power strips connected to each other from the wall plug (each of them with 3 extra plugs - that i can fully use without having a power outage, but never things like 2 heaters).
Is this a no? The daisy chain? It's the only way i canmanage to connect stuff around the furniture arrange.

I use like that since ever the only problem that comes to me with that is using "heavy" things like two heaters in that daisy chain but i never need or use two heaters. Would it be problematic using a pc? The pc would go on the first power strip. Sorry for such long reply but i'm trying to sort this out.
