As an electrician its totally fine to draw 3500w on a 230v circuit. You should get outlets that are rated for 16A continuesly and not just 16A Peak (10A continuesly), but other than that you are fine. A 16A circuit breaker wont even do anything unless you draw at least 14% more which is just slightly above 18A

[@aaronlucas8162]

I love how Linus points out the input voltage rating, but totally ignores the input current limit of 10 amps right next to it. I was hoping to see some kind of generator like tony starks ark reactor inside, as that 10 A input limit gives a max output of 2400w at perfect efficiency on 240, so at a minimum it needs to pull 1050W out of thin air to attain rated capacity. If you were the low end of the input rating, it would need to probably draw near on double the rated input, if not more.

[@UsmanSiddiq1]

Chinese translation is bad and I am pretty sure it was saying 10Amps X2 or per unit but you gotta understand one thing. Asia uses an open air cable system and power reaches each house after 2-3 freaking block lvl transformers and countries have something known as Nation wide grid, where if one producing unit is faulty it is compensated by other units. So Yep our voltage is usually very very stable.

[@craigape]

That must be an issue with the labeling then, as they achieved over 2400w in their limited testing.

[@ichbinla.aa.ngweilig]

@@UsmanSiddiq1 The 10A is the rated power of the C13 connector. The PSU only has one. Its power rating suggests that it draws more than 10A. It does not matter how stable the power grid is

[@RJ-wx3fh]

Even in the UK, where we have 240v wall power, the max rated from one socket (unless you run a fresh breaker at higher rating) tends to be 13A . Now it's nice getting 3120W, but still a few watts short of this power supply's advertised rating

For those who doubt the danger of a power supply... Even as a kid, I had the sense to not plug things in before testing sketch stuff. It was a REALLY old power supply, where you had to plug the leads into the power supply... but the sticker was gone so I didn't know which side to have the different pairs. So, I plugged it into the wall and used a stick to flip the power switch, and it promptly exploded. Fortunately, it was not a big enough explosion to break the steel casing but it definitely set off the smoke detector.

[@Darklight171]

[@riothero313]

I had one go bad. It would shoot a arc of voltage out of the hdmi cable every time you tried to plug it into the tv. Weirdest thing ever. It wasn't just a quick spark either, a full solid arc like a stungun that would jump from the cable to the tv's socket lol.

[@wachocs16]

I see linus has a lot of fear against live wires, even more at 220v. I used to use a soldering iron with a lot of spots in the cable burned from the soldering itself. One time I got shocker in the leg while simultaneously touching with my hand a metal cage connected to earth. I received a shock (220v), moved a bit scared out of surprice and continued soldering. Nothing too bad. The problem is when you grab the cable with out hand while earth connected, but touching it with a finger it wont kill you

[@draconpost]

haha, that was just a blown cap. it's fun when you just connect them directly to 230v and watch em blow, or use a small torch on the side of them (they are supposed to blow at the top) and shoot the hot blown insides at people XD they stink tho (like toxic gasses should) so do it outside

[@mattbennion779]

To clarify this was a catastrophic failure. I couldn't even pick up the box for some time because it was so hot. It was a lot more than a blown cap. This was a supply that hadn't been plugged in for a decade that had power flowing the wrong way through it, probably shorting as it flipped the breaker as well.

6:54 that is an PTC (Positive Temperature Coefficient) that is used to limit in-rush currents and not an NTC. As a high current passes through it and it warms up, it's resistance increases (hence Positive Temperature Coefficient) and it therefore limits the current, after the capacitors have charged up, the current decreases, the PTC cools does and it's resistance goes down and it has done it's job. a NTC would let more current through as it heats up, which is not what we want in in-rush current protection application.

[@someguy4915]

That is exactly what you want in in-rush current protection?... Small start current, increasing to full capacity after the capacitor is filled... What you're describing is full in-rush current (instantly trips the breaker) followed by lower current (too low to run the full 3KW psu)...

[@antecboy]

@@someguy4915 I believe you're more correct on this one actually after I rechecked the use cases for the input protection cases for the NTC and PTC. PTC is more suited for possible short-circuit events, so they limit in those cases the more sustained current draw times. And I might have also mixed them with polyfuses, which share the PTC characteristic thermal-resistance behavior with current. Both can be used in current limiting applications.

[@reptarien]

@@Zombified- I think you have some fundamental misunderstandings about the difference between LTT and GNN... They are very different tech channels. LTT does more experience and power oriented content, with a bunch of whacky shit inbetween, while GNN does more results, raw power, and usability of devices, and have always been way more technical than LTT. LTT is branching into more technical content, which does mean that of course there will be some overlap in the technologies they use, but I really doubt Labs will be stepping all over GNN's feet. The scale Linus is trying to take Labs to is on another level entirely, if he succeeds. GNN will always have a place on this platform, Linus and the team wouldn't want to erase them entirely. They're all good friends. Alright sorry for the couple of paragraphs, I'm just passionate about the content they both create.

Fun fact, in the US and Canada, we don't have only 120V. Most homes also have 250V. Everyone knows the = and the =o plug but we also have a 3 prong circular one (2321 plug) which tends to run on 20A circuits, and 3 phase 4 prong circular one (3P4W plug) that runs on 50A circuits, which can push 5000W and 12500W respectively. In our homes, not workshops or something. It's weird they don't get talked about ever. It's for heaters and AC and such, most older washers also ran on one of these. But theoretically they could be installed for any purpose if your appliance was wired for it.

[@DJRaffa1000]

@@kaldo_kaldo yeah, i saw a video from technology connections about the US electrical system. Kind of weird to have a ground point in the middle of the transformer to get "2x 120V" from your 240V supply line and then use double breakers if you need the full 240V. Here in Germany basically all (stationary) devices that use 3phase innately are wired up directly without a plug (like literal wires into the deevice) but we also have 3 phase plugs/sockets for construction equipment etc. which can push 11kW or 22kW respectively. I'm sure there are alot bigger connectors around but those are pretty easy to find, especially the 11kW one which makes charging an EV a breeze if the on-board charger and charging brick support it.

[@fvckyoutubescensorshipandt2718]

5:00 LOL at the switch wiring. That was done so a cheap 12vdc 1A switch could be used rather than a 240vac 15A one. Penny pinching, just like the missing components that says let the EMI be damned (probably a FCC fine waiting to happen, surprised they are not import banned).

[@HappyBeezerStudios]

Obviously it wouldn't be able to work with a 240V 14A switch anyway. 3450W on 240V with less than 100% efficiency.... from their claimed "90 plus" That would be 3833W, which on 240V would require a 16A fuse.

[@fvckyoutubescensorshipandt2718]

@@HappyBeezerStudios eh 15A can be overdriven an amp or 2 and never trip due to breaker manufacturing tolerances if you really push it and bin the breakers (usually 10% tolerances for cheap ones). The wiring can actually carry 2-3x rated current fine (ie insulation just getting warm, not melting) if the run is short. Most ampacity tables are for keeping voltage drop under 3% at stated amps rather than for temperature rise. Apparently the PSU won't mind if the voltage drops to as low as 180 (25% drop), but the breaker and wiring would with the amperage required to do that. It would be very difficult to run 3450W at 100% load anyway if using it for it's intended purpose (presumably a mining rack, and most mobos for those only have 8 gpu slots with each underlcocked = maybe 3kW).

[@WouterVerbruggen]

"How could you possibly expect to get 3450 watts out of one c13 power connector?" Simple, by neglecting its 10A max current rating. XD They work fine at the full 16 A of a breaker circuit giving a plentiful 3600 watt. The actual limiting factor is the cabling, which often is too thin to carry such amounts of current without melting its insulation. Also actually the EMI filtering is for keeping EMI originating from the PSU itself from going into the rest of the grid.

[@chrisakaschulbus4903]

So you could build a little circuit that puts EMI into the grid to ruin it for everyone else?

[@RJ-wx3fh]

Really efficient, if single use, house heater if you do that...

[@GuusKlaas]

I love how the "how do you get 3kW from a single power connector" question is a very north-American thing. Large parts of the world actually run 240V rather than 120V (it's also more efficient, heck, it makes EV a lot more manageable as well). 3.4kW is only 14.2Amps, usually groups are secured to 16A here. Lot of stuff such as electric hobs and car chargers even sometimes do multi-stage, such as an 11kW home car charger using 3 stages at 16A each. I'm not saying you should "just" put a 14A load on any random outlet, but honestly it's not much different from a laundry dryer or an oven. Lot of houses have 3x25A total nowadays (some still on 1x40), and you can get (but it's more pricey) 3x35 easily (more is possible but it involves a bit more work), so typically this kind of power is 'no biggy'. Is it smart? Nah. By no means. Entertaining video though, nonetheless (@Linus Tech Tips: perhaps an interesting subject as a journalistic piece: explore the challenges of power grids in electrification, I do as if 3x25A 240V is a nice thing here but honestly we struggle as well even with load balancers because our PV, our heatpumps, and our cars otherwise would... blow fuses, can NOT imagine how that would work on 120V...).

Note, the US is 240 volts, we just split the 240 into 2 120 volt phases. An electric car charger in a US home can easily,(and regularly) be 240 volt

[@ReyMysterioX]

Quite a lot of word for missing the fact that C13 is only rated for 10 A, regardless of voltage. So even here in sensible 230 V country, you're not supposed to be getting more than 2300 W over a C13. If you want more, you need to go C19.
