Between this and the ridiculous TDP expectations for this generations latest graphic cards people are going to have to start thinking about using dedicated circuits per gaming computer.
- fartsucker69 4y agowho cares about these russian gas problems. I will have to throttle my cpu so it doesn't get too hot in winter
- imdsm 4y agofeeling a bit cold, gonna turn on my gaming pc for an hour
- thegagne 4y agoWater cooled? More like water heated, amirite?
- cameronh90 4y agoMy office gets about 5c warmer when I play games on my PC, despite being poorly insulated with the window open. And I've only got a 3900X+2070 Super...
- izzydata 4y agoAnd also use the heat from their PC to boil water and then spin a turbine to generate electricity to sell back to the grid.
- Nextgrid 4y agoFor people who use resistive electric heating I've recommended them to run crypto miners on their computer. Same efficiency with regards to heating, but you can earn some extra money as a bonus.
- undersuit 4y agoI lived in a little apartment with resistive wall heaters and I did just that in the 2018 period. Even had some Raspberry Pis mining Aeon, a lightweight offshoot of Monero.
- nibbleshifter 4y agoI've done this to heat the small room I use as an office, its far more efficient than the shit electric radiator in there. Rented house so can't do much about the absolutely useless heating setup.
- JustFinishedBSG 4y agoAlready there in Europe... I actually prefer getting the Steamdeck out than turning the main computer on for "light" games.
- rjbwork 4y agoI actually did this...I got two dedicated circuits put into my room - one for the window unit AC (no point in cooling the whole house when I really just need to cool this room most of the time), and one for my gaming computer. My work laptop, lights, etc. are all on the original main circuit of the house. A friend of mine is an electrician so the price was very reasonable, and it has been worth it, especially during this hot summer.
- nerpderp82 4y agoAre you exhausting the gaming computer to the outside or into the room you are cooling?
- rjbwork 4y agoInto the room I'm cooling. I suppose it would be possible in theory to do so, but the particular layout of the room makes it difficult to impossible to exhaust both the AC and computer, I think.
- Arrath 4y agoIn previous heat waves I've seriously considered venting my PC through the wall straight to the outside, but alas I currently rent.
- nerpderp82 4y agoDo you have an inroom AC unit? You could run a dryer hose from the back of your computer to the same window vent.
- tristor 4y agoI did something similar for my home lab setup in my previous house. It was pretty reasonable having two dedicated 20A circuits run w/ surge protected hospital-grade outlets and dual function breakers. Each circuit fed a different UPS which fed a different PDU so everything had redundant power back to the breaker panel, which was all I could reasonably do residentially, and it meant none of the servers/network gear impacted the rest of my office circuits. It was reasonably cheap, and in my next house I'll do the same again. Running additional circuits is pretty easy if you have an attic or crawl space.
- PragmaticPulp 4y agoNot really even close. Even with a 235W CPU and a theoretical 600W GPU you wouldn’t actually exceed even half the capacity of a single 15A circuit in synthetic benchmarks that stress the system beyond real-world loads.
- mlindner 4y agoPeople often use power strips for their computer. So you also have your dual 4K LCD monitor system, as well as maybe plugging in a phone to charge as well which can have high peak power draws over USB 3.0.
- ip26 4y agoFor sustained loads you are only supposed to draw 12A, and the PSU has a conversion loss, dropping you to perhaps 10A of power for it all. Plus, then you can’t run anything else on the circuit.
- zrail 4y ago10A is ~1200 watts. That's quite a lot.
- dagmx 4y agoIt’s easy to go over when you start factoring in other things like monitors etc A beefy CPU, GPU and a couple of high end monitors can take you to the edge of that and over.
- tristor 4y ago> It’s easy to go over when you start factoring in other things like monitors etc Why would monitors even be factored in? They shouldn't be on the same circuit anyway.
- collinvandyck76 4y agoWhy wouldn't they be on the same circuit? The monitor and computer are in the same room and would generally be plugged into the same outlet. I think this would be the rule rather than the exception.
- 404mm 4y agoThis is the definition of “working smart vs. working hard”. Not everything about the CPU needs to be solved by pushing it to the limits of physics. TDP is not linear relative to CPU freq.
- hotpotamus 4y agoI had a LAN party at my house in 2012 and one lunatic brought his 1KW+ PC and tripped a breaker which has seemed really twitchy ever since.
- UseStrict 4y agoCircuit breakers do degrade after being tripped. Once usually isn't enough, but repeated tripping will wear them out.
- hinkley 4y agoYou should have an electrician check the wiring too. You might be leaking a little current due to decaying insulation. If you have to wire a room, ask for a larger gauge of wire so have the option of a larger breaker if you want it.

- pentae 4y agoIt certainly makes building Mini ITX a lot more interesting when you're trying to get the sweet spot for performance to thermals/noise ratio. I did a nCase M1 build recently and my objective for the build was small as possible, quiet as possible, and as powerful as possible in that order. I still ended up with a pretty powerful machine by going with an i3-12100 instead of an i5/i7 which uses much less power and puts out less heat. The RTX 3080 reference card was the biggest card that could fit into the case which I undervolted. A lot of people are undervolting their RTX GPU's because for an only about a ~3% performance loss you get about 10C less temp which translates to far less fan noise. I don't know why Nvidia doesn't just have a one click button for people. nCase unfortunately have discontinued this case based on 'market factors' which I suspect means that they don't anticipate things to be getting smaller and cooler any time soon.
- plasticchris 4y agoUndervolting actually let me over clock my 3070 higher, presumably due to extra thermal headroom? I noticed two peaks in the timespy results and undrrvolting moved me between them, so this must be pretty well known.
- ChuckNorris89 4y agoMini ITX is also insanely more expensive than building a regula tower. Sure, if you're only putting the most expensive CPU and GPU in it then probably it doesn't matter to you but for value oriented builds, miniITX case, Mobo, PSU and cooler add up a lot.
- pentae 4y agoYou can get a great cheap ITX cases these days for about $50 (Cougar), A 650w SFX Power Supply for about $70 (Evga), ITX motherboards start at $110... then just make sure you choose a sensible CPU/GPU from there based on your power supply. And if you're using entry level cpu/gpu then you don't need to go crazy with cooling either. Certainly not much more expensive than a regular mATX build imho.

- mox1 4y agoFor those of you unaware, most households in the USA have 15amp circuits for their wall plugs. With that you can safely pull about 1200Watts constantly. I am unsure what the normal household circuit amperage is in the EU or elsewhere...
- quickthrowman 4y agoMax sustained load on a 15A breaker is not 10A/1200w, it’s 80% of 15A at 120v, or 12A/1440w.
- kuschku 4y agoThe normal amperage in Germany is 16A at 230V, with a peak load of 3500W and a sustained load of 3000W.
- Teknoman117 4y agoI popped the breaker when I accidentally connected my gaming computer and my car charger (plug-in hybrid) to the same circuit. Probably would've been fine if it were a 20A circuit and not a 15A, but it did remind me how much power these things draw... Or with power in SF averaging 40-ish cents per kWh a standard evening gaming session can easily cost a non-negligible amount of money.
- gwbas1c 4y agoIronically, I have a printer that really needs a dedicated circuit. When it warms up the toner, it draws 12 amps for 1-2 seconds. Printing often pops the breaker. I had to move the printer out of my home office into a bedroom, but even then we've popped the breaker when printing while vacuuming. (It's not a case of bad wiring, either.)
- thehappypm 4y agoThere are types of fuses that have a time delay on them for this purpose. A lot of electrical appliances have that kind of startup burst of energy. An electrician can tell you more
- Marsymars 4y agoIt's not an AFCI breaker, is it? My last house had sensitive AFCI breakers that my laser printer would trip about a quarter of time when warming up.
- gwbas1c 4y agoYes, my electrician was going to change it for me; but then I plugged my printer into a kill-o-watt and learned that it was pulling 12 amps. I've been assuming it was current, because if it has the circuit to itself, nothing trips. (My office only has one circuit, which is dedicated to the room. I could have asked for 20 amps, but it didn't occur to me.)
- zerocrates 4y agoWarming up the laser printer (and its a small one) reliably causes the lights throughout my apartment to flicker.
- birdyrooster 4y agoI used to own a brother laser printer and it did this, I switched to HP LaserJet and this no longer occurs.
- thehappypm 4y ago253W is only 2 amps in the US, thats like 10-20% of a breaker’s capacity
- simlevesque 4y agoWith the GPU it's going to reach 51% at this rate. That's all it takes to require one per computer.
- hnuser123456 4y agoJust realized everyone's gonna have to turn their power targets down when running a LAN party. I gave my brother my old 2080ti, something would coil whine when he played Battlefield. We turned the card's power target down until the whine went away. We found at 35%, the whine stopped, and the performance difference was not easily discernable with a basic FPS counter just flying around a MP game. Opportunity for software that dynamically adjusts CPU and GPU power targets in the middle of various games, learns the game's power/performance profile and whether it's CPU/GPU bottlenecked, and optimizes perf/watt while maintaining a given FPS target?
- dralley 4y agoThat's what Radeon Chill is.
- xeromal 4y agoI believe the new 4x nvidia series uses 450-500W. Throw in 2 monitors and a speaker system and you're coming close to overloading your 15amp breaker.
- alasdair_ 4y agoPeak draw for even a current-gen graphics card is well over 500W. There are rumors that a 4090 will need as much as a 1500W power supply to run it. That's almost a complete 15A circuit just for the PC once you factor in cooling, speakers, monitor etc. I already have issues where the breaker would pop with my current gaming PC if it fully spins up and I had to get a 20A circuit put in to handle it (mostly because there is more than one computer on the circuit).
- xani_ 4y ago...no. Average EU circuit is 230V/16A, that's 3.6kW Even if you ran 1kW (...somehow) you could still connect 3 of them and still have 600W left for audio/monitors.
- SketchySeaBeast 4y agoYou're right, I was being North American-centric, which is 120V/15A and could only run a single 1000W machine.
- FieryTransition 4y agoWe usually only use that high amperage fuses on high power appliances, like ovens or workshop equipment from my part of Europe. I would say it's more normal to be fused to 10A for most indoor things, anything else is not normal, as most home appliance power cables are not even thick enough to carry the 16A 230V power safely.
