Just two cents here, and I figured it's time for another stupid experiment.

Videos Brought to YOU by Kim Rod and the cable Wad configuration.

If you want custom cables for your computer, you want them custom made with your colors and your choices, and your config is you can do that on the cable mud configuration.

The support All major brands of PS use both modular and semi modular, and you can have cable extensions made.

But the best part is previously they offered aluminum cable combs and only black and white.

But now you can get them in various colors.

So if you want to take your system to the next step and really make it pop, get some custom cables and make him your way.

But the cable mod configuration You could start playing around that by using the link in the Description Bluff.

Today we're doing another experiment that could quite honestly end up bad and is dangerous, and you shouldn't try it at home.

Why does it seem like we're always doing things that like could literally cause damage and harm?

I'm not gonna deny that, but this is one that quite honestly could end in fire.

That's why our fire extinguishers are handy.

And you should not try this at home if you do again, your bad, not mine.

So I've attended a few land parties in the day and it's always kind of made me like You know what?

There's an awful lot of computers and stuff plugged into this extension cords.

So I'm kind of curious as to what happens if, like, a where the diminishing return, in terms of like power turns dirty with extension cords comes in.

So what I've got right here is 325 feet of the cheapest, most unreliable least amount of insulated harbor Frayed ish extension cords.

And what we're gonna do is we're gonna use our test bench here, which has 8700 k over clocked five gigahertz and a 28 e t i.

I gaming ex trio graphics card, which is a custom car that could pull an awful lot of power.

We've got hooked up here to our kilowatt, so I can at least keep an eye of how much watts are pulling through this now for a little caveat.

Lot of you guys are in other parts of the world.

We like to call things miles and inches and all that sort of stuff.

But we also use the 120 volt system here, where a lot of other like special, like European countries use, like to 10 or 20 or something different than what we use to 40 isn't to 40.

That also means that you guys get much more efficient power and you get, like, cleaner power to your power supplies and stuff, which we don't get.

So we're gonna kind of do some testing here to see exactly where we find instabilities with this.

Where I had to make a choice of hardware I wanted to use because this one I want kind of to be indicative of what the mainstream consumer would probably be using.

But what I'm saying is, now that you can get 32 core 64 thread, thread, rippers and like nebula over there, which has got to 20 t eyes and, uh, 1980 xy and uses a lot of power.

I wanted something that's a little bit more realistic, and there's another reason why I'm doing this video.

If you guys remember the season that I was on scrap yard wars, we when we were building the systems and we had our own little workbench and I was doomed by quick over clocking because we were really running late on time, which is always the case in those texts competitions I performed in over clock in disability testing on our 47 70 k.

But then for the final shots, they brought in extension cords and push the tables together so that we could be next to each other for the final reveal.

And suddenly my over clock was no longer stable.

And Linus is like, Oh, I thought you knew how to over clock.

Ah, and then suddenly he got unstable and he's like, I want a ups and he went and got a ups and then started being doing the carny cry baby stuff that he normally doesn't Scripture at worst.

And what we realized is both systems went completely unstable when we were running on, like, 100 foot extension cords across studio.

Once we went into a UPS extension cord to the ups to the computer, which conditions and basically load line balances the power going into the system, our stability came back.

So that's kind of one of the reasons why I'm doing this as well.

This extension court right here is one that I actually made.

Um, this is made with, like, a construction grade cord.

Made it myself because I couldn't actually buy one.

This was in response, everyone that was like, Oh, my God, You're using Rome X on the ground.

And you guys yelled at me, so I changed it.

So this is what we have going straight to our fuse box over there.

So this is a short cable that is of the highest quality.

Okay, so, um, try the sea the baseline test 10 minutes, if it'll do it, not crash.

So it's been running for 10 minutes and 30 seconds absolutely no problems, no hiccups, no stutters, no nothing.

I could see what we also decided we want take a look at is volts.

So right now with the extension cord, it's pulling 118.3 volts.

Remember, this is a 120 volts system here.

So what we're looking at here, too, is as we had extension cords.

How much dis drops cause what's gonna happen is as this goes down, it still needs 120 volts.

So it's going to start pulling more amps to get the votes it needs to provide the wattage that it's being that's asking for.

So that's sort of how the math works there.

And the reason why I'm even pulling this out is it dawned on me that when I hooked up the first extension quarter, I saw that say 1 17 So that may not seem like a lot, but you start dropping that down like 1 16 1 15 then that starts to have a big discrepancy in terms of the cleanliness of the power coming because of the resistance that re adding with the extension cord.

Now, the reason why we're getting that resistance is because we're using a 16 gauge wire.

If we did a 14 gauge or a 12 gauge with the lower the number, the thicker the wire, the less the resistance.

So I'm using this cheap extension cord because this seems to be more so what?

I think an average person would run out to like the hardware store and pick up.

It's just all the deeper one, and we'll go with that.

And I'm not thinking about these other things.

So the 100 foot cables plugged in It says 118.6 bolts don't want to see if that drops when I turn the system on 1 17.51 17.31 71 So we were probably start monitoring.

Now that we know what the what is going to be exact, why just give me the same.

The system's calling for the water just like a PS.

So is great dissertation in the comments why we're here.

That 1 17 1 it just dropped 1 16 51 14 1 13 because Cinna Ben's just started.

So we're clearly getting resistance through one wire.

So if we look at the voltage here, it actually came up slightly.

1 14.4 So now we're going to add, Oh, I got the wrong end.

All right, so it's pulling 108.108 0 too.

So it's definitely pulling about five more volts.

Or I should say, there's about five volts extra resistance, uh, with the 2nd 100 foot cable and we have with the ones we were at, like, 1 13 before now.
