Opened the case and grabbed the cable... All wires are black. -.-'
Same problem with me :-(
AX860 - all wires are black and the connector is two separate ones of 18+10 pins, that is 28 pins, not 24 (even though the text on the back side of the power supply days ”24 pin ATX".
@@Mina_be 24 pin that plugs into MOBO is standardized. So that means manufacturers have to put PS ON wire on the same place no matter the brand/model/color of wires etc.
If we are looking at 24pin from back perspective (cables are leading into 24pin connector side) the PS ON wire is 4th from the left going toward right.
you can find a pinout of ATX power supplies on Google
Hold up so clip is on TOP and holes facing you. From the top left count 4th hole. THAT is your GREEN.
Why not ship a PSU tester with all your units like EVGA does. Not everyone wants to reenact scenes from MacGyver or Hurt Locker
this is truly a test just to test for it to "turn on" since there is really no load on it at all. I have had issues of really high end PSU's running just fine all the time, but when the power hammer comes down in full effect under massive load they crap out. No real way to test unless you have expensive equipment.....especially anything 1.5kw and beyond!
Cool, now I just need a paperclip... I'm serious.
Lmao why do I need such simple things no usb key to do a BIOS update and no paper clip to test my psu
Indigaming 3500$ build and I have no CD reader to install my drivers 😂😂
@@roflimjokes nobody uses cd drives anymore anyway haha
@@AdoptedPoo lmao I know now but it’s my first build in over a decade! I was panicked ready to go back to the store my cousin had a good laugh at me
@@krakata-na-fiki Wow, never expected that
Great quick test! My friend left me a TX850W and performed this test, and worked without a hitch! Thanks!
This was probably a great video 7 years ago. Corsair needs to do a newer one with the AX series PSU's. I'm seeing a lot of people - myself included - online in forums having problems using a bridging plug or jumping the motherboard plug with a paper clip to test fans, water loops, etc.
I'm using an AX1200i and I cannot get it to power up using a Bridge plug. I checked the PSU's specs online and the bridging plug is jumping the correct pins on the plug. None of the fans connected to will power up either when jumping. I plug it back into the motherboard, HDD's, etc. and it powers on.
ill swap you for my ax which does power on with the paperclip but wont run anything else 🤣
I was in contact with corsair about my faulty PSu to s
Do an RMA.. Once we verified the PSU was faulty he ghosted me... Great job standing behind your product corsair
Watching this in 2020 and still super helpful! I was taking apart an old custom PC, looking to upgrade the parts and whatnot. Tried this tip with the paperclip on my Corsair CX 430 and found out it worked like a charm. This was after trying to power on the PC when it was all together, so maybe the issue is with the motherboard or something else.
But after how long should you replace the power supply?
NOTE:
Your PSU fan will NOT turn on if you have a PSU that will perform silent (fanless) up to a certain load such as the AX1500i.
This is why it's always a good idea to hook up a fan to a molex connector.
(The AX1500i has a self-test button but that's beside this particular point.)
how would i connect a nzxt fan to a molex cable?
@@JustNotIt9927 You'd need a 3-/4-pin fan to molex adapter.
The spit swallow was way to clear to hear for comfort
Lol
It's just irritating😣
Better to swallow it. Spitters are quitters bro.
I have a modular one and all the wires are black 🤣💀. But i just remembered the positions where the wire was placed and boom it worked.! Thanks 🙏
This is my problem lol but idk the locations either 😅
This was a extremely helpful video. I disconnected everything (even all the RAM) from my motherboard except for the CPU, CPU cooler, and chassis fans. Then I unplugged the 24 pin connector did the paperclip trick. LEDs and fans started working whereas they didn't work before. The problem seems to be with my motherboard since it's very unlikely that CPUs go bad.
Why did you unplug RAM, etc if you anyways unplugged the PSU power connector? PSU anyways got disconnected from Motherboard no?
@@PuneetMehra I don't remember all the details, but I shared your concerns about disconnecting the PSU before everything else. The test regarding starting the PC with no RAM was just to see if it would post (or give any sort of different message through blinking lights). I forget if that is even a valid test for RAM or not.
Wow I tried this as a last resort before ordering a new PSU. Turns out it wasn't even the problem, thanks Corsair! Definitely have to pick up some Corsair products now.
All my wires are black on the RM850x :(
top row, pins 4 and 5 if your wires are all black. pin 4 is power and pin 5 ground. on atx standard.
Whoa! I was almost pissed! It worked and thanks a lot. U guys should incorporate test switch for paperclip free ppl.
He sure bent that paperclip back pretty fast.
Maybe the 12v+ rail is working but the 5v or 3.3v could not work :-" in this case you should get a multimetter at measure the output betwen a black and a red wire for 5v+ and a orange for 3,3v to see if it's ok :D
Yes bro, I have this issue. This check was fine, but the atx power was not received. The CPU fan spins but the USB and 3.3v / 5v on-board supply were not working.
is this safe to leave 24/7 if taped up? trying to power 8+ pc fans in my reptile hut
Thanks for putting this up. It's helpful to be able to verify my new CX 500 fails this test. The PSU fan spins for a fraction of a second and then stops. Will be contacting RMA.
I had this problem to. Do your sistem work properly after replacing the PSU?
thanks for this vid! first time builder, wanted to make sure my power supply worked and this test worked.
I have had a RM 650 for two weeks and it has already stopped working. Do you how much it sucks to have $1200 of PC parts sitting there doing nothing
Feel you man my rm750i stopped working 2 days ago.
same thing happen with my 4 month old CX550 and i just bought the CSGO Hydra access pass and now i can't even play it with my friends :(
I don't like my vs series mustard colored wires its ugly :( how does other people have black? do you not need color coding?
Yes I very much do.
I do
Hey I have issues rn with my cx650f rgb and all my cables on this 24 prong one are white so I don’t see how I can do this any help
Omg i was scared but now it’s working ✌️thanks a lot bro and merry Christmas 🎁🎄 😍
iwas trouble shooting for hours thanks to this video i figured out the motherboards 24 pin is the issue thanks
All the wires in my 24-pin connector are black ....
Thanks for posting this video, helped me figure what was wrong with a system that wouldn't start up
My corsair cs850m has failed unfortunately and this test has proved that.
this is a very intresting and useful tip for all pc users and especially for me that i am a new one, to find and propably fix (via replacement) my psu, one of the most basic pc parts, so thank you corsair !!!
To test the if it really supplies power, touch the paperclip?
👀
I learned something new today, thank you!
How did you plug the fan?
What happens if your PSU works, but is the cause of random restarts? Do power supplies lower output over time? Mines 9 years old but still works, kind of.
love you, the 850 m power supplies not starting whitout a minimal power consum.... thanks
i got a ax860i a couple years ago and still cant use it . keeps kicking off only way to get it to come back on is to unplug all the cables out of the back then plug them back in . might run a day or a week before you have to start over and do it again worth mentioning this thing was big $$$$
yes. connect it at places such as the molex.

oh hey thanks for showing me how to connect the power supply to a fan, ....
Use the fan on the psu
Edit: nvm 7 yrs ago
Hey man 7 years later😂
@@rafathamaan1201 nice :)
Fantastic test idea. All with just a paper clip!
Corsair , you are the best ! I have your memoty ram and i have that hx 1000 for 1 year and half , everything is running smooth.
Thank you.
All of the wires on my Corsair RMX Series RM650x, 650 Watt connector are black, there is no green wire.
Someone who works at Corsair should know that not all the cables on a power supply are colored. Mine are all black.
I did notice that it is the 4th wire from the left on the clip side with the pins facing you and the 7th wire.
My old TX550M not only has black cables. Also the pin layout is lacking in the manual. Thanks
Excellant. It worked perfectly with my Antec HCP-1200. Great video. Thank you.
@LAHrebirth
no this is actually a fairly standard procedure, it isn't stupid, and it isn't dangerous if you know what you are doing, dont just jam metal objects into any pc component, however testing a psu in such a way the video demonstrates.
however something that bothers me is that people put too much trust in "the guy who sold me the pc/parts" most of the time this guy is just a store clerk, he knows the name and price of pc parts, and sometimes a couple specs and requirements
Hey Jeff mine was destroyed by a brand new corsair Hydro 100iv2 pump hose explosion. I'm going to have you guys test it. If The RMA was expedient maybe my unit would be sitting at corsair already. getting some consumer love but I know I will be missed when I know longer support Corsair and their PR tech support, + the long delay in the RMA which leaves my new PC build of 2 months DOA.
Just ran the test and my PSU works. I'm scared now...Maybe my motherboard is blown...OH NOOOO.
Thanks. Test was very helpful though.
im kinda interested after 4 years of this comment... Do you remember how your PC actually was? What was actually wrong lol
@Voodoo Man so how was it?
@@kuzb2800 he died....
@@eddiejr3934 _last online 5 years ago_
Ok I have a major solution to your problem. My pc also did this and I fixed it by checking that i did not change the "reset"pin with the "power" pin, or they were not the wrong way or not pushed in properly. Please check this before replacing it!
@mkiv15 I doubt it. It's just the motherboard signal, probably just a few volts if that.
I followed your instructions but I don't have a fan so I connect it to the power supply, however the fan ran and again it stops moving.
When I first tested the power supply, the building was shut down
My Corsair RM650x does NOT have a green wire, all wires are black. So how am I supposed to do this test? thx☹😵💫
Why not put a PSU green light next to your off/on switch. Save me the trouble of buying another case fan.
I keep a 25 dollar Antec PSU in my tool box in case it looks like another spendy Unit won't power on.
Thanks Jeff, this helpful clip tip, I'm sure will also come in handy.
what if its a flat cable and they are all black? :D
+StaticFX yes why did they change the color coding rofl
The pin layout must be the same, no matter what PSU, since it has to plug in to various motherboards and they all have to work the same.
The video doesn't show the pins very well, but Corsair website does: 4th and 5th pin from the right, when you're looking at the connector, and the locking clip is on the bottom.
This video needs to add a diagram to show which pins to be shorted.
The green pin to any ground (black) should work
For the users that have the HX 1200, this PSU has 10+18 pins instead of 10+14. In order to jump start PSU's with this kind of layout: Have the 18 pin connector with the lock clip looking upwards, from the top row of the pins count from right to left, you need to put a wire or clip in the pins 4 and 5.
can you pls provide a link to where Corsair shows the gren and black pins well?
I just ran a similar test without a case fan attached. (I will have to get one for it). I have a brand new Corsair RM650i PSU. Anyway I started up the PSU with a paper clip. I measured all the pins outs of the PSU with a digital multi-meter, and only one +5V is working. (The PSU fan test works.) On the multimeter I get about 0.25V on the 12V line.
ax860 here. mobo argb lights are on ( 5v) but the 12v is deado. powers on, straight back off and wont turn on again without a reset (mobo lights stay on). paperclip same effect.
I got the vs650w and the light turn on, fans don't spin, nothing turns on on the screen.
Anyone have the same problem?
right i had help with my mate who knows how to build a PC i installed every component the way i need to safely. (I made sure i grounded myself) I finished my build to power up the computer. Nothing happened. I followed a check list to make sure everything was in right etc. Then i did this test with a 550w PSU which is more then enough to power up all my components. The test passed but the psu does not power up the motherboard at all.
So, now I need a video detailing how to connect the fan to one of the power supply dongles.
Hey man you got how to Hook up the case fan to the power supply?
Helpful, so helpful, thanks for posting.
A Fluke my voltmeter was enough load to get a CX600M going since getting a fan required standing up and a piece of coax cable core saved another trip for a paper clip...
Old, but still relevant. My PSU came with a self-tester, which basically takes the place of the paperclip. You just slide it on so the black cord curves onto the green cord (easy a pie, really) and then plug in the PSU and turn it on. Works like a charm.
I didn't have to plug in anything to it and the fan started up. I assume that's enough to know it works, but I'll likely talk to my uncle about it and find out for sure.
Great video.
...now if I could just figure out how to get these decals to stay on my metal case. I wonder if static electricity causes them to pop off in certain spots or if it's just that the adhesive is too weak. I don't know if it's even worth keeping, since I might want to remove them one day and anything permanent would prevent that or damage the case...
I am plugin the psu but my fan do go on also none cable are connected to nothing only the main Power cable for the psu no cable is connected to any fan or motherboard pleasee help
Just need metal that will conduct electricity. Any conductive metal is fine to use, so long as you can actually bend it and fit it in the holes on the connector
I didn't have a Sys. fan with molex connector, so I plugged the molex into an old dvd drive and have the same effect and could eject the dvd... Found out the MOBO is fried and the PSU is fine....
Well i just found out my psu wasnt working because the HD Sound "ground" wire was reversed from the case.
Btw this technique worked, and told me that my psu wasnt the problem. Guys please note, NEVER DO THIS IF YOUR PSU DOES NOT HAVE A LOAD (Always connect it to something like a cpu fan when doing this test) If not, bad stuff will happen....
Or in my case, how to test whether your 4 month old corsair fried itself
lol same for me EVGA.
This only shows that the PSU can handle a fan. It doesn't help me determine if it can handle the stress of having a full pc connected to it. It is an useless test.
Thanks ! you guys saved my few bucks ! btw.. why does this problem happens.. My build was working fine and then suddenly there was no power to mobo, cause my MSI ez Debug light were not turning on... then i followed the above steps, and everything worked fine again.. why?
the RM1000X has all black wires! is does have labels 1-24 on the pins but I can't find which numbers correspond to those colors...
How are the PSU and the fan connected? Do I realy need to buy a sata to molex adapter just to check?
most power supplies have a molex prewired
A little difficult to follow when the rm850x consist of all black psu cables
just recently bought cv450 my problem is I tested it with only cooling fans connected and when i turned the switch on fans are working even without a paper clip just like you did. help fix thank you
I bought a corsair RM 1000 w and it exploded while I started my new PC, nice job corsair
very useful video, thanks a lot bro you made my day
Now we can proof if the power supply can turn on.
What we need next is how to test if the power supply actually work, and work under load within specs.
awesome, worked like a charm.
I didnt have a paperclip but i have jumper wires haha.
I have the HX850i and tried this test the initial power on the PSU fan spins than shuts off but the connected fan still runs.
Is it safe to leave it plugged in like that for years at a time or would the paperclip be a fire hazard (or damage power supply). It would be nice to be able to recycle low watt power supplies this way, if its safe.
should be, i have seen lots of people powering stuff with PSUs, just use a bit of wire to bridge across or cut the green wire and attach it to a black cable
This test actually works! As for those with black wiring, all the "colors" are labeled in the owner's manual, so its easy to test it for that as well. I was using a Seasonic 750 Watt Modular Powersupply, so I can't vouch for other companies.
My old TX550M not only has black cables. Also the pin layout is lacking in the manual.
I make the bridge between the 2 connectors as show and the output tensions are right (3,3V 5V and 12V) and the rgb fans turn on (only fans connected as in attached image). But when I connect the PSU to the Mobo (ASrock Z97 gen 6/Intel i7 4790x/ first attempt - ASrock B450 pro4/AMD Ryzen 5 2600x second attempt) NO POWER at any time. So the voltage is OK but the Watt power NO.
Paperclip test. Prodding capacitors and sparks flying came to mind.
Funny they don't mention the danger of destroying the PSU by plugging the thing in and activating it without any power OUTPUT.
Vidéo intéressante Merci, cependant j'ai une VS 550 en panne peu servi, ou puis je avoir le schéma pour la dépanner ? ( wiring diagram )
Thank you ! So the PSU ain't the culprit. But PC still not powering up. What could be the problem?
What if the leads are not coloured?
My TX650 will spin for a second and then stop during this test. Do I need to replace it?
Wow, computers are really complicated, yet fun and simple to use with proper skills.
I'm having problem with kernel log power error ID 41, my computer turns itself off and becomes inresponsible while playing games or using programmes that take more than 1GB of RAM, eventhough I have 2 GB of RAM.
Your comment made me realize this was posted a decade ago lol
I have rm 850x psu which just start giving sudden shut down and dont turn on until you wait for 5 to 15 minutes.On game it always shuts down pc and sometimes on normal use but more interesting is vs550 runs perfectly even on games no issues at all.
Got a CX750M PSU around a year ago, and it failed already, actually disappointed in this. brought it due to the brand name, calculator said id be fine with the wattage with what im running, but for some reason it decided to over heat and filled my livingroom with a lovely burnt smell.
thx for help im going to contact then my German Corsair Help Center for my Rm850x
I was playing WoW and mine just shut down. I disconnected everyting. After that took the tower to the living room, open it and make sure that everything was connected properly. Everything was fine after a while I plugged to the wall and it was getting power but wouldn't stay on so I turned the switch on the Corsair on and off while i was pressing the turn on button on the tower and it worked.
All my wires are black genius... CX650M
@costi08 Or get a power supply tester. You can get them for $10 in some computer shops, probably cheaper on ebay.
i did this and smoke came out of power supply unit, and fans did not turn on but somehow pc managed to turn on, rng?
Very useful, I doubt if I check the voltage or the power of the PSU are normal making that connection with a multimeter? Thanks!
What if the power supply fan spins shortly then stops when connected to the motherboard?
its the exact issue i got
***** same..
***** The problem is mostly with shorted diodes, not necessarily the main diodes used for DC rectification though (if a cheap PSU) but any diode in the PSU could be shorted.
If you have a high end PSU like the RMx, HX, or AX series, then the fan will automatically shut off when under low load. It might work.
my corsair vs550 have this issue also
so when the fan spins but you hear a sparking noise from inside the box, that's a blown psu, right? (TX650W from 2009 here)
Can you tell me which Pin Connector you're having inside a Corsair HX1000i PSU and which Fan Diameters and Sizes it Supports? Just in case i want to install a different Fan
For Example:
Could i replace the Stock Fan with an 4-Pin PWM 140x140x25 Fan?
Thanks, but the corsair cx750 dont have any green cable !!!!
Nice try.. the HX1000i we procured has a Motherboard Power Harness from Corsair with ALL BLACK WIRE! How Now Brown Cow?
Actually no. When that happened the PSU was OFF, but I left the plug ON. Which still shouldn't have shocked me, but I guess the current stayed even when it was off for a couple of seconds.
It works properly on an antec, thanks Corsair :D
This might be a stupid question... I'm troubleshooting a HX750... when I do the paper clip method, the fan on the PU turns on and the cpu fan turns on but after 2 seconds the fan on the PU stops spinning but the cou fan continues to spin...shouldn't the PU fan continue to spin as well?
