The "Warnung" is the actual German word for "warning." You can tell it's meant to be one of those multi-language labels because of the Spanish "peligro" below it and the French "attention" to the lower-left. The issue is they didn't put a single other German word on it.

AND don't forget to crimp the fine strands of the flex ! Also the German / Koren system does not let you touch live contacts (in opposite to the literally shocking Canada / USA system) ...

He changed the outlet, didn't mention he wired it wrong, and he "borrowed" our bedroom AC unit (a $700 Friedrich 12000BTU unit that worked flawlessly and had a digital display, remote, all sorts of nice features) to test it and promptly let the smoke out. Of course they fired him over this, but offered to replace the AC unit. When the property manager showed up all smiles with a 5000BTU $98 Walmart unit thinking that was a perfectly adequate replacement, we filed that away and when it came time, chose not to renew our lease.

The probable reason the PSU case is getting hot: The internal transformer works at high frequency above 20,000 HZ and is working way above it's Ampereage capacity, as a result, it's High Frequency magnetic field expands beyond it's physical core structure, as a result, the AC magnetic fields bombard the external steel case, heating it like an induction cooker. I've seen the same phenomenon when a high frequency transformer is overdriven. The more you know. A few things to look for: The extension cord modified for 240 volt: I see a fire risk because the indicator light on the business end is now dissipating 4x the power. they are neon lamps with a series resistor.

I think the 3.3V and 5V rails together are not supposed to exceed a combined 150 watts and that is why they are stuck together in the table. It is a quirk of how some multi-rail power supplies are designed, usually because there is a tap on a secondary winding of the transformer that causes this where if they were separate secondary windings altogether it would not have that limitation. That leaves 150 + 1800 + 6 + 10 = 1966 watts total which is close enough. They may have just mislabeled the 12v rail.

@KABAKOKSEK Often times consumer PSUs are built to offer options on how you want to distribute the total wattage.

This in essence is a problem for all older type of devices like washing machines and frigdes that used pretty simple 3-phase motors to drive them. Difference between 60hz and 50hz is about 20% so it basically means that your fridge/washing machine either runs too fast and can be damaged because of 20% boost (if it runs on 60hz but was designed on 50hz). Or the other way it runs 20% slower and basically is less powerful in comparison to what is should be.

Even easier yet, as well as more flexible, would just be to buy a North American 240 V extension cord and put their 240 V connector directly on the IEC cord, so you'd still have just one plug to replace and it would be utterly clear (because of the short cable length) that the IEC cable was 240 V.

Sorry just a correction on the video... The MOV section is totally wrong, although the silverstone showed a MOV. The parts in the "2000w psu" are actually NTC parts, more specifically ICL devices (inrush current limiters), completely different from MOV parts. They are resistors that are temperature sensitive, helping to reducethe initial rush of current (due to charging capacitors). This initial high current load causes them to heat up and therefore lower their resistance making their effect on the circuit more irrelevant due to lower resistance at higher temperatures.

8:15 NTC thermistors is used for inrush-current limiting. When the capacitors on the input side of the PSU are fully empty and the NTC is cool to the touch the NTC thermistor adds resistance to the AC circuit to gradually charge up the capacitors over a longer period of time instead of trying to charge them up very quickly all at once. As power starts to flow through the NTC thermistor it begins to heat up and the negative temperature coefficient (NTC) means as it heats up the resistance gets lower making the NTC thermistor look more like a direct wire in circuit instead of a resistor. So it might start at like 18 or 20 ohms but as it warms up it changes to less than 1 ohm over a fairly short period of time. It basically makes sure you don't blow the mains breaker when you first plug in the PSU...
