Did this video help you?

pattric7: yellow & black... all that other crap threw me off ....what,s hook,t up to what ... i can,t follow the orange & black wires whats all that for i wanna use it for afx track l.e.d.s lights thank,s for showing me how to cut off all that utter crap make it cleaner

mahabubur rahman: Great V!deo .... very neat.. thank you man! just want to know , how many 12V device i can use at a time? if my 4 device all together 200w , needs 10A minimum , do you think it will work safely ? Thanks again ....

henry bannar: I do not understand why no clips for repairing the car stereo itself I have typed the right words but other thing come out 

The Antagonist: How to make your own power supply. First you'll need.....a power supply. LOL sure. 

Mike Bell: Great job kiddo

Ibrahim Nabil: Can i use this way for charging 12V car battery ?

MARCOS NEGRON: I have two Dell power supply but when doing the green and black nothing :(

Jetset Willy: thanks ... but you can do it in 3 minutes not 23:48

andycharger: I have a quick question that im sure you will know the answer to! I have cut my wires and twisted together the green wire and a black ground wire so it is always on when i plug it in.When i plug in the mains cable, the fan on the PSU spins up quickly then stops instantly. There is no power getting to the device i have attached. are there any other wires I need to attach together other than the green and a black?

reza oll: PLESE FOR I C

reza oll: OPTILINK NUT FOR DISH NETWOR POWER SUPPLIES

reza oll: IC NOOOOO

Kobor Hamath: Kobor 

Rock-O River: OK so I am done with everything, I now have 2 sets of yellow wires and 2 sets of black. What do they go into? What I am trying to get is a 12v power supply. Do I connect all the yellows into one and the blacks into one then attach to item? I need it for my robot! Thanks. 

Mattje Jonas: who can hear

Jan Venter: I am glad he does not work for me,because what he did,any halfwit could have done in 3 minutes

mitropoulosilias: i charging my car battery with lipo-charger (use another selection in menu) and no problem!

Vandwo: Would advice the same as Tom Smith, resistor on the 5v rail if its ATX 1 standard with powerful 5v rail or resistor on the 12volt, if it is ATX 2 standard. So you can place the switching power supply in nice smooth working mode.

prince ace: need help asap i have 2 wires that are half black on side and half yellow in the other what shall i do with those ?? anyone

Norman Waithe: thank you very much you are great

Loco Llama: this is not "your own" power supply your just wiring it how hard it is to find a simple video that explains the does and don'ts about making a 12 power supply

Jose Laboy: Just wanted to stop by and say thanks for this video. I was able to make my own power supply to juice up my car amp at home. 

Ricardo Garcia: Greetings; Can anyone help me accomplishing this? My stuff: 700w Blaupunkt Amp 500w Power Supply 1 x 40 Amp car fuse 2 x 140w Speakers I will probablt add a sub Woofer I am aware that i may not be albe to get the volume to it's max. Since the power supply is just 500w only. I've cut 4 yellow (Voltage) wires and 4 black (ground); Joined them toghether (yellow with yellow; black with black). My questions here goes to: I am using a 40amp car fuse. Can i leave it on as security measure? Are both 4 cables (ground and voltage) enough? Thanks in advance 

Tom Smith: Hi - should connect one of the red 5 volts wires through a 15 watt, 10 ohm, wire wound resistor to a black ground wire to make it work properly apparently Fred in UK.

Auckland M. Zapata R.: hey nice video, i have a question, can i connect two of these modified power supply in serie to get 24v?

William Wynn: KC9WAE had asked if this would work for a CB radio. The answer is NO it's only pulling 0.4 amps. Depends on your radio, ex.. say a Cobra 29 may needs something like 4.0 Amps A high end radio may need 7 to 10. JCarrot Selby asked about the music at the start. Its a Swiss band, Yello and the song is, Oh Yea. 1985 - 87 something like that. 

321reh: A Most Excellent Video...Time Well Spent....Thanks!!!! 

KC9WAE: could you use that for a two way radio or ham radio

Power: no there are not

superbawlz: What a tard!

Markko: hei , if i have six yellow 12v wires , , i can get 12v to 6 different items at same time from each wire 12v or , is 12v for all wires at same time , like if i take 7v from one yellow12v wire then otherone can give only 12-7=5v ??

joe miniclip: long and freaking stupid.X(

rcflyboynj: Make sure that all the unused wires are insulated, and that the power supply is unplugged when you are connecting wires.

kevin james: Am I the only one that wonders if he burned his parent's house to the ground yet?

MCm0u5e: Good vid! Thx

Frend Zii: get of the dudes nuts . if u dont like it why did u watch it ?

rcflyboynj: Make sure you have the green (power on circuit) wire soldered to a black (ground) wire. That will allow you to fool the supply to thinking that it is in a computer and to turn on and remain on. If that does not work, go through and make sure that all of your excess cables are insulated and not grounding out to something. If you have any other questions, feel free to ask! :-)

Dan Nixon: A couple of points, you could have put some kind of end termination on the +12V and Ground rails, like screw terminals or something, would have made it so much easier to connect to, and why not make it so that you can use all the power rails, not just +12V, you never know when you may need one of the other voltages, I did this a while back and included all of the power rails and it is such a useful power supply.

tramjoemerin: "To make your own DIY power supply, you need: ..., ...., and a _power supply_".

wildybill: the device will draw what it needs, there is no too much when it comes to supply, only too little.

raymond detz: hi i have a rc hobby and I have a 12 volt power supply of the PC 15 amps but that with every model I have now are a q-tec modeladt-300 can also

FanArtist25: yea, but instead of powering a CPU you can power anything that uses 12V. ie. most 10-15 inch TVs, a USB to charge your phone/mp4, or take a 12V step down and charge a portable game system.

מרים פרץ: theanks dude you are awsome!!!

rcflyboynj: If you are not going to be using it, just cut it short and insulate it with tape.

Jamie Oliva: Thanks for the demonstration. Keep up the good work!

Carey Po: Hello I have a hipro model HP-D2537F3R that I want to use live a variac by adding a knob to control the voltage but I also want to add a switch so that I can still use leads coming from it as presets like my +5,3.3 and 12 is this possible

bpiper122: The use of a resistor is for switching power supplies, because they won't work without a load. The resistor acts as a load, of sorts, and the current used is wasted as heat. Continuous power supplies will work simply by grounding out the green PS ON wire, as shown in the video.

chamuco90255: Dude I have the same problem. Im trying to power up a car amp. Before I cut everything I was able to get it going, the music was blasting :) But once I cut everything(to make it look clean) the stupid thing wont work. I dont get it??? Runs for like a second n then it dies. I feel like I just ruinned a perfect psu, n washed money down the toilet. Can someone please help!!!

Darrius Reed-Lockhart: Could the power supply catch on fire after u do this.
