now touch the clip for extra fun
☠️
It's always more fun when it's almost free!
Well... it's only 5 volts, so...
Nothing would happen, there will be no voltage flowing through your body
@@SuperAbsolute1 You just made me go recheck what voltage it is, and guess what, it's 5V. xD
*touches paper clip*
Jesus: hello.
Me: oh hi
nothing happens, touched it a million times so far :)
@@alphadurk9483 Hey guys this is me after dying for some reason he let me send one more comment or something like that to you guys so you’re actually wrong I didn’t go to Ohio
@@Gaming_Assassin_ 🤓
The voltage is low, i touched it already
@@kyria_kous really
Dead ass thought you were gonna end it after using the paper clip on the switch lmao
Lol
its too low voltage, pretty sure that even if the psu was on, and you touched the clip, you wouldn't even feel it
@@mathdantastav2496 yup, 12v dc output of the psu is nothing dangerous. Whats more dangerous is the 120v or even 240v ac input and processing inside the psu
@@mathdantastav2496 that's not what the comment meant
@@mathdantastav2496 they meant when they turned it on by pressing the paper clip into the power switch
This video needs a disclaimer, homie. 💀
Why?
@@64bittz93 to fucking isolate the paperclip to not get zapped ffs
@@profesorstevabakmaz4822 or simply dont be anywhere near the paperclip and only handling that part with non steel objects/tools
@@profesorstevabakmaz4822 the paperclip wont do crap anyways, the voltage is too low
Electrician here: 5V DC isn't deadly. It might hurt a little but that's it.
Thanks! Now I can use my psu without my pc!
(Edit: My house burned down)
Have you tried turning on and off?
Maybe some rice will help.
😂
But at least your psu is running
The power suply cannot explode if you put the cables in wrong pins

Nice
@@WolfyRed wow thnx guys 😀😀
Don't be sad it's over, be happy that it happened, God I miss my childhood, but we all have to move on. Hard to do though.
@@Shuruii yeah true that🙂
i forgot to turn it off 💀
You ok?
@@ballsuckervr ye im fine
That’s fine. Why are you people acting like it would shock you??
I just did it and no shock at all 🤦♂️
@@Acidburn3141 it was meant to be a joke i know that it wont shock you because its 12volts but it still isnt safe
@@slappi6979 its 0v
If it’s a psu with all the wires the same color you’ll have to count them carefully to find the right one
Or just look up a pin out diagram.
Hey, I remember using that trick when testing a old motherboard two years ago, unfortunately it was not working
You were supposed to touch the clip 💀
Some power supplies are not dumb and know what your doing
This is super helpfull for buying used powersupplyes!
This is like making the heart beating without the brain
That's actually a very apt description.
My brains heart is pretty small, I want to take the body to a gym but the heart is not strong enough. Will a second heart make the body go to the gym?
It's actually pretty common in society now
true
I found this out when disassembling an old PSU, which you absolutely should always take proper electrical safety precautions on, as it has high voltage capacitors.
Never take appart psu without knowledge
For example dischargeimg capacitors @@309electronics5
Back when I was in electronics class in highschool and we ran out of proper power supplies for projects in the lab we used to do this to get 5 and 12 volt power, we ended up burning up so many components all the time lmao
But why?
@@dimka11ggg too much current
This is a good way of powering your water pump when filling your custom loop.
Fun fact switch mode power supplies (the kind you find in PC's) need a few ohm load to output the correct voltage. So if you have it connected to something that isn't powered on you want to use a resistor to make sure the voltage doesn't spike too high
In any high quality supply there will be internal resistors to do just that
All modern PSUs have smart monitoring that automatically detects output load and adjusts the voltage accordingly
Holy Shit youtube just trolled me because the video bugged and went black right as u hit the switch I wish I could have screen recorded it istg this is real I'm actually shocked
Reminded me of the struggles I had back in the day.
I had a GPU which required a 6-pin connector, but the motherboard I had lacked a 24-pin connector (it was one of those dell optiplex/hp prebuilts)
So I had one PSU powering the PC, and another PSU only powering the GPU. I had to start the GPU supply first otherwise I wouldn't get a display
oh the struggles haha
Nice lmao I'm at that point ATM hopefully will get a proper motherboard soon lol
I had a similar situation tonight and I managed to get everything running with this video 😁
I tried that to check if my PSU is working and it worked. But the path will depend on the PSU that you have bought. Some PSUs have all black cords so make sure that you are getting the right port
I needed this thanks
Damn the amount of clueless people here with lack of knowledge is insane. Touching the clip when it's connected is NOT dangerous at all, because, 1. Its a signal. Ground to green wire needs to be connected in order to turn the psu on. And 2. Its only 3.3, 5 and 12 volts. That wont hurt you. Even if its ac.
Though there something I did learn, don't do it at work when your having to test tech for them just let them stay confused. (I was banned from testing technology for them to sell for months)
That gravity falls theme is epic 🗿
I had a broken PSU when building the PC and this test helped me know it wasn't the motherboard but the PSU
Going thru the same thing. Been looking for some way of testing out the psu. Glad i landed here
Hmm what happens if I to-

What happens if you use Bacon Grease instead of thermal paste: day 8 of asking
Dont cook yourself 🥺
Omg he doing it
even more dedication
I'm honestly surprised he hasn't done bacon grease by this point
Ah yess !! the gravity falls theme in the back.
My dad did this once, I still use that power supply
famous last words Nothing but a paperclip
Day 1, : 1.What if u use whipping cream as thermal paste
2.What if u use cpu as thermal paste (cpu placed on cpu)
3. What if u use ice cream as thermal paste
4. What if u use concrete as thermal paste
5.what if u use cement as thermal paste
6. Chocolate as thermal paste
7. Cloth as thermal paste
8. What if u run cooler on 1.5v battery
9. What if u use coca cola as thermal paste

nope
Thanks! It functioned!
God putting that 24 pin together together sucks ass, looks like some pristine work man
Day eighty five of asking mr yeester to use ink as a thermal paste alternative
thanks, I got electrocuted
Me: chilling to the gravity falls background music
It worked for me, thanks 🙏
Great strategy, using a resistive wire shorting a power supply!! No fire hazards here.
... do you not know how a psu works? Black and green wire needs to be "shorted" in order to turn on pc, as a signal...
@@breezetix and is that wire resistive? What happens if someone touches that wire and they are grounded? I think it’s too hazardous. Besides what is the point of turning it on without using it?
@Chriss4123 you made no sense. Yes the clip is resistive obviously. It's connecting green wire to ground to SIMPLY turn the psu on. If it shorts 3.3n 5 or 12v then psu simply turns off because they have short circuit protection.
@@breezetix Ah, forgot about anti short protection, although that might not be triggered with a resistive wire which would limit the current flowing through it. So based on what you said those wires produce a very low voltage and when they are shorted the power supply turns on?
it doesn't work that way, the PS_ON wire which is green needs to have its voltage level at 0V to be able to turn on the PSU, aka shorting it to ground is the way, but for the rest of the wires, yes it's a hazard
Bro at least put a disclaimer or something to not do this 💀💀 what if a kid did this and touched the clip??
The clip doesn’t have voltage, nothing will happen if you touch it
@@zacharietelles7626 it’s shorted to ground 💀, it doesn’t have any voltage
when my motherboard wont boot normally, I used a folded aluminum foil to short psu from back of the wires(it was from 2013) and replugged the cable in the 24 pin while its on. It worked flawlessly for 2 years and still working
Thanks so much...now I can check voltages before I chance hooking up another MotherBoard. The original MB burned out (Capacitors burned out).
Hey lads am watching this from heaven
yeah screw all the risk, free fan to cool at when my house went blackout
Instructions Unclear: I now appear to be 6ft underground in a wooden box
Gravity falls theme *instantly likes*
' Instruction unclear ' power supply flown away
Thanks brother you help me alot❤
Bro you know too much . Thank you ×77. It work ❤
Thanks for this extremely useful tip that will make my pc definitely work
Thanks for this video
I will save it for future
You Can Also Do This To Check That If Your Smps Is Working Or Not In Case If Your PC Is Not Turning On Or Something Else Happe
The music in the background is from Gravity Falls, if anyone is wondering.
We did this at school in our "Introduction to computing systems and networks" class
yep, really useful
I designed a little printed circuit board to let me easily toggle on and off a power supply for use with building electronic projects
how are you going to disable the over current protection? or are you using it for low current electronics?
@@electronnuclear overcurrent protection is a very desired property, as it protects me from being a stupid idiot and shorting out my circuits for too long
it's really low current applications, maybe like 1A at most, so a 500W PSU with a 17A limit on 5V is *plenty*
@@catgirlQueer well I've used computer PSUs for the same but they turned off as my load increased and I had to restart it. So I ended up buying a 12v 10amp smps. Obviously it was a cheap Chinese one.The output current can extend upto 13amps at 16v(has a variable voltage range from 11.9-16.4v) max load. For protection I'm using a dc-dc converter as it can automatically regulates output during short circuits
@@electronnuclear that's fair, but for my purposes I really don't need anything more than a few amps at 5v
Instructions unclear i poked the capcitors, now im typing with one hand.
When he stayed turned on I feel like there is some idiot who just died 😂
clippy was a paid actor
super charged clippie
Lol my rig has 2 psu, 1 just for graphics card and i have it set up like he showed. And one psu for the motherboard....this not a joke works quite well actually

The forbidden solder gun
wait! mryeester does video without ads? no wayyyy
Bro just invented a infinite power cheat code
I remember doing this in my Cisco class to find out if psus gave off the correct voltage
Bro is gonna run cyberpunk on that paper vlip

This is actually a really good way if you want a solid 12 volt source if you take the positive and negative leads off
Ahh yes, gravity falls theme song in the background
Yes a paperclip needs power
I learned about the paper clip test in my computer maintenance class, since I want to be a PC technician, I think it is very useful if you don't have a power supply tester.
Instructions unclear i now have pipebomb
I had to do this when I was testing a car head unit
Just a fan* dangerous can explode*
It would have been better if he added an explosion at the end 😂😂
On older PSUs, the pin you should use is the green and gray pins (PS_ON & GND)
This is very safe to do. Its common practice to do this method to turn on the PSU as it then supplies power to other devices, notably a pump for a watercooling loop to prime a loop without powering up your entire rig, ensuring minimal risk during leak testing! Nowadays many higher end power supplies come with a 24pin female port with the earth and psu on leads pre linked so you dont need to go scrounging for a paperclip like this.
I've been doing this for years. Computer power supplies make good high current 12 volt power supplies like car radios.
Tried this like 2 months ago with tweezers when my pc wasn’t turning on just to make sure my psu wasn’t dead. Then I measured the voltage form the separate pins with a voltmeter
Uhh, my hands went kaboom
Try to connect the grey wire too with both green and black and now you can put some load on it
this is a common method for testing PSUs by shorting the 5V PS_ON wire (green) to ground to turn on the PSU without involving a motherboard, but is also a dangerous method to use if there's a short on anywhere, i burned quite a few capacitors forcing the PSU to turn on this way before noticing shorts
Instructions unclear I'm now dead
You could probably use this for troubleshooting to check if it works
that boi just created the most powerful paper clip the word has seen
recommended for do tests in your PSU after build an pc.
Only works on some power supplies. Some motherboards won't output 12v until there is a load on the 5v rail. Usually this is on more expensive power supplies.
I did this will a dell power brick to power my gtx 970 on my old hp prebuilt gaming pc. Worked flawlessly.
Also can use a safety pin with head cut off. Spring loaded positive contact
Instructions unclear I accidentally burnt my house down
Commenting from heaven, instructions unclear, I touched the paper clip and suddenly i'm in heaven, probably a teleport error. please fix
i touched the paperclip and i lived. (it's only a lil warm my guy)
Thx is working 💪
The 8 bit guy
Use the yellow and black for 12V while shorting out the green and black.
paperclips are probably responsible for the majority of computer hobbyist deaths and this is why
Lmao Gravity Falls Theme Song
Beware, running a high power PSU without load (i.e. the mainboard) can lead to overhearting and damage the unit.
