This is one SKETCHY 2000W Power Supply

David: "You have life insurance right?" Dell: "Yes, We sold him multiple warranties"

I love how they arbitrarily labeled it with 95 Plus Gold because 95 > 80 therefore better; but not 100, of course, because that would just be silly.

You can tell Kyle is an engineer by the way he refers to parts. Also the bit about why he hasn't sent a product yet hits home.

In three wire 220/240 volt(or four wire for that matter) where the two hots go doesn't matter since they are completely opposite phases and are indistinguishable on the device side, it also doesn't have a neutral because it creates a phantom neutral at the center point of the two phases

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.

I love how the least sketchy part of this video is probably the 2000W power supply itself

I think I would've just made a resistor out of nichrome heater elements to test rather than plug it into all that juicy hardware.

15:55 not all cables are actually copper, especially in cheap PSUs. Some use copper clad aluminum, or even just straight up aluminum

Alex: "Don't touch these" Kyle: immediate physical contact

It’s funny that PSU testing setup for 6160 USD was missing the device measuring power draw for 30 USD.

i love how they treat the 240 v cable like high tension or something, when almost everywhere in the world you use it to power your blender at home.

Kyle: points out the tool cabinets full of tools Alex and Linus: still yolo with whatever tool is closest to their hands

I miss these types of "Don't ever do anything you see in this video, but here's some detailed instructions on how to do it" videos. It reminds me of an old video where Linus showed us how to make our own 7v fan speed reducer out of extra molex adapters.

okay, I actually jumped at the point where they pranked Linus when he put his head against the PSU. Send this to GN as a gift to see if they can blow it up with their tester.

the 13:36 "hey stop" i felt that lmao

@Linus Tech Tips - You would be much saver when fixing a German / Korean style (recessed earthed) outlet to the output of your modified cable , because Germany has 230 Volts ( + 16 Amps) & there are plenty o IEC computer power supply cables for German / Korean outlets ... the 2x 110 Volts in Canada / USA are no problem at all because the German plug / outlet is not polarized anyway & some regions use 2x 110 Volts with German style outlets (50 or 60 Hz) ... 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) ... Trust me I know what I tell you , I'm a German & I did serval plugs / outlets my self & even connected a 3 phase stove ( 400 Volts) without ANY incidents over the years

I test car and home amplifiers to show their actual power output because this has gotten so out of hand! Many use “MAX” ratings we call “ILS” ratings (if lightening strikes) 😬

13:35 is one of the best jokes this channel has ever seen

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. Unplug when not in use.

I really love the chemistry between all of the LMG employees. It's like they've all been friends since childhood lol. Get yourself friends, colleagues and family that you can smack-talk and roast for fun, that's where true happiness is, in my opinion.
