David Benjamin Laliberte says:

Brilliant thanks! So if the fan turns on then there’s something wrong with the motherboard?

Carlos Gomez says:

Nice and crisp information. Can’t make a mistake.

LopsidedEdits says:

What do I do, I have the 24 pin cable from my psu, but it is split into 20+4 pin, and the 4 pin is too short to reach the mobo, so it can’t go in all the way. Any recommendations?

JBaciJ says:

Say .. hypothetically one forgets to unplug the 4 pin connector and other components from the PSU, but one still happened to paper clip and turn on the PSU. Would this cause any potential damage?

Mark Heitz says:

I have tried this and I can only get the PSU to run fan at low speed. The project I have is I want to link up 5/6 tops 12vdc fans so thought this would work , I also bought a driver 12/20v wondering now if would cook them or would it work as if used a transformer each fan would receive less voltage can anyone tell if the driver would work or would a simple 12 v driver be able to handle so many fans or what’s wrong with PSU please please anyone tell me Cheer’s

Seth Grubbs says:

my power supply works to an extent as in I turn on the pc and the fans spin as if booting up (mind that i have just built this pc) and then they just stop and nothing works? Any solutions?

Robert Knudson says:

very helpful random youtube thank you!

Abdullah waqas says:

i have no yellow wire in power suppy which is ised for 12v plzz tell me which wire is used to get 12v

Prickled Panda says:

i did this with my psu and green and black would turn on for a couple seconds then turn off but green and blue would leave it on.

i bought a new motherboard asrock fatal1ty h170 perhformance edition
just finished installing it to my pc and plug everything

now my pc wont powering on from the power button
i already checked the cables and the ram and the cpu and everything

no leds light no fan spining while pressing the power button

so can i do this trick or no ?

Penny Ripoffs says:

My cpu doesnt work, i plugged all the wires correctly, even the fan doesnt spin. Is my psu damaged?

Georgie Thumbs says:

What do you mean “jump”? To test if the power supply works or jump it because it locked up? I was just at my computer and all of a sudden it shut off and it wont turn on again. I took the power supply out but the cables are still connected and nothing happens when i turn it on, the fan doesnt move or anything. Nothing looks burned out. Is is locked up?

BuddyIsSavage says:

Welp I got a dead mobo

bringthedarth says:

Thanks for teaching me that a nice jumper adapter came with one of my old EVGA cards. I never realized that’s what it was for! Feel like an idiot now! lol

James Stinnette says:

I just finished putting my new build together and I want to test my psu because the computer will not power on at all. Do I need to completely disconnect the psu from my mobo in order to test it or is it safe to simply disconnect the 24 pin and test?

Vinsof Isaac says:

Can I use this to run a graphics card ??
I ask this ques bcuz I think if I shut down the pc the card would not !!! is it safe ?

George Negrici says:

by doing this could it mess up de psu when using it for a longer time lets say 4-5 hours?

Nazri Usham says:

Thanks a lot bro 🙂

Michael Street says:

Thanks for killing me.

ѕρeαк fαcтѕ says:

I’m to scared to do this i value my life lol.

Daniel Birx says:

Aaaaaannnnnndddddd I wasn’t paying attention the second time I did this and did the reverse side. But nothing really seemed to happen, hopefully everything is all good lol

Great video, short and to the pint. Kudos!

OneShot Gaming says:

Thanks so much for counting over the wires because my psu is not color coated and their all black! This video help me a lot! lol Its my first build and i am kinda a nervous nanny! I am really nervous it will not turn on! Any tips?

Victor Renan Covalski Junes says:

thanks man! cheers

R. Sergi says:

A very great video, and a question emerges: Can a single ordinary PC (say, gaming PC) have 2 PSU then? For example, I use the first PSU to connect motherboard 24-pin, and then I want my HDD, fans, etc connected to the other PSU with a jump start.

Zfast4y0u says:


is this 1000000% safe to do? i mean does every manufacturer of PSU has same order of this wires ( not expert )??? i have corsair rm1000x, it has all black wires, i will have to drain my luube for repaste and i will have to do leak test, so jumping PSU will be needed, i really dont wanna fuck up my psu by jumping wrong wires!!!

Paul Rahe says:

Thank you. You solved my problem.

Abaasi Abbie. K says:

Thanx Buddy.. Very Helpful 🙂

Roman Ruiz says:

I did this with a 650w PSU and, after several trys, a cap exploded leaving a very nasty smell behind. Fortunately for me, since I farted almost right after the explosion (because of the distress), I didn’t have to deal with the smell for long.

You should probably indicate that this process isn’t safe for every PSU. Thank you for helping me fuck mine (and yeah, I did short the correct pins).

Joshua Albuen Secoya says:

How about it runs during paper clip diagnosing then it won’t if you put it back on to your pc

shadow10hunter says:

Can i use a jumped psu to do non-computer related stuff like a high power water-splitter or something?
Will extensive use of the jumped psu damage it?
Useful video, by the way.

Ferryanto Gunadi says:

thank you!

Reddix1993 says:

So, by using a power supply jumper, could you run this long term with no issues?

George Anastasopoulos says:

A very good video on testing a power supply unit!

Kyliou 301 says:

is it safe?


sir,can i keep this jum starter wire all times in the supply!anything ill happen??ill it blast if i keep all time the wire in the supply??sir and also i can feel a small shock on the wire if i touch thm

DSM Dallas says:

I turn it on, and off it goes! no sir, you turn it on and on it goes! LOL

Rick Mateo says:

Hi I just bought a lenovo m92p desktop and want to use my 500w psu,but issue is psu has 24 pins & mboard has ony 14 pins,it fits halfway,half of the pins are out of this ok to turn it on.

shiva kumar says:

love you

Carlos Gomez says:

Here is a silly question. Could I use an LED as the mechanism to short it? That way I could see a light too. I read that the voltage of the green wire is 0.06 volts.

Absolute Zero says:

Thanks! But mine appears to be DOA since it came as a bundle with the case.

Brandon Wright says:

Thanks bro GENIUS!

Papadi Baba Latisha says:

Thanks broo..
Nice and work for me.. but fan running slow.. can i use for 2 vga 1070? Is it save??

Duncan Wallace says:

This does not work for the Thermaltake G1600 and 1500 psu’s because 1) they don’t have a power button and 2) the cpu cable needs to be plugged in (at least that’s the only way I could get either of these psu’s to power on).

Jason Voorhees says:

My 24pin has 1pin missing is that ok?
