[@robertcartier5088]

At around 5:00, you drill holes through the metal case, just above the circuit board. That is NOT recommended. Removing the circuit would be best, but if you're lazy (like me), you can put a large piece of duct tape across the inside bottom of the side you are drilling. Stick the bottom edge onto the case and let the sticky side drape over the circuit board. Any metal shavings will be caught on the tape instead of shorting out your board.

[@reculture]

I guess it does job for you and it serves its purpose, however with just a little bit of effort and couple tiny changes alongside you could've made it slightly more capable and closer to that of "endless possibilities". If you bundled same color/voltage wires together you could've pulled out more current/power on each of three outputs (3.3V, 5V, 12V). This workaround is fine for motors, heating but it's probably not much useful for low-power electronics neither it's stable enough as it is. To get around that, it's often useful to connect a 10W resistor as a dummy load to one of 5V outputs (since 5V output provide more current). By doing so, PSU detects load and provides stable voltage and current across all 3 outputs... As a alternative you can also power on psu by shorting green wire with black on ATX connector using switch and so on... Those are just a few from top of my mind, as you can find yourself many good variations on internet...

[@Roel_Scoot]

Not that new because there are many simmilar video's, but nice try. Little tip: if you use a screw on terminal do not solder the cable ends because on the long run the solder will ooze out under the pressure of the bolt an will make bad contacts. Better to use a crimp on cable shoe, or the bare wires.

[@twotone3070]

or simply become brittle and snap off under pressure from the screw. Not so bad if you are using rising clamp blocks.

[@vasu615]

Since we can get 3.3 to 5.00 Volts DC through Computer SMPS, can it be used to charge mobile (its current rating is , I think 5 Amps DC).If so, Mobile Battery may loose its life early because of high rating of charging.Clarification requested.

I know very little about this, can you tell me why you need all the cables and not just one of them? assuming you will use less than 100 W of power. what is the requirement to power security cameras on a distance of 50 meters? do I need thicker cables? do I need a more powerful power supply? what happen if I draw 400 W off a 500 W rated cheap power supply, is it safe or it will damage the power supply fast? Sorry for my English

[@clueless3891]

Different voltages, for example yellow and black are 12V, red and black are 5V... Dont use cheap PC power supply for cameras and 400w from 500w PC power supply is not a good idea. My advice is to just go to your local surveillance shop and buy power supplays and cables for your camera model

hey very good, a question are you getting 110V AC or just DC 12V

[@clueless3891]

3.3V-20A, 5V-13A, 12V-13A, 24V-0.3A but amperage are different for every power supply, this is some old china power supply

[@robertcartier5088]

rupert roman (and Mirko Ivkovic), This design is a nice, easy solution for small loads. But to be clear, you cannot expect that much current (amps) if using only one wire for each voltage, as this design suggests. Use at least 3 wires of each color for heavier loads. (This was mentioned before but I bring it up here because of the additional amperage details in the author's reply.)

very cool! what is the BLUE -12V used for?

[@clueless3891]

-12V+12V=24V blue and yellow but just 0.8A, good for dc motors for high rpm

[@robertcartier5088]

fitnesspoint2006, If your question was what is the minus 12 volts used for in the PC, it is used on certain circuits or components that require both a positive and a negative voltage at the same time, for different sections of the same circuit or component. An example of a component that sometimes requires both pos. and neg. would be an Operational Amplifier (Op-Amp).

[@FXV]

Great vid

[@benassy69]

2:40 I don't like that part. You should've snipped them from the board or unsolder them.

[@boowonder888]

it works, but by not combining the wires by color he loses most of the aps of the psu. If you want it to run a heavy motor, you gonna need the amps.

[@mgsamps]

Not necessarily, on cheap PSU's like this all the wires of same colour/voltage are actually connected together on the circuit board and come from the same SINGLE output, be it 12v or 5 v, if you want to draw a lot of current then it is just safer to combine the wires at the user end as together there is less heat and stress on 2 or 3 wires than one.

[@robertcartier5088]

MG Samps, When I started reading your comment, I was wondering why you were seemingly disagreeing with boowonder888... But, it turns out, you were just explaining it a little better, but basically he meant the same thing you said. I was just confused there for a second. ... Never mind. ;-)

[@mgsamps]

Robert, boowonder's answer is misleading in that he implies by not using ALL of the same coloured wires that we would get less current capability, which is wrong as they ALL normally terminate to the SAME solder pad of the pcb and have just a single output stage for each voltage rail (the extra wires of the same colour) are used to power other parts of the computer like multiple HDDs etc, you would still be able to draw the same current with one wire but it may get quite hot if you're using the total current stated on the PSU case for that power rail . More expensive psu's from the likes of the top end Corsair's, Enermax etc will have 2-3 SEPARATE 12v and 5v circuits with their own rectifiers and filtering, if the psu states 3 x 12v@20 amps, 2x5v @30amps then his point makes sense, but that would not be the case in that crappy Chinese psu he is using or ones like it.

[@robertcartier5088]

MG Samps I don't remember any mention of multiple rails... I invite you to do the math. There are destinations for those wires that require more than one wire in order to supply enough current for that particular device or circuit. Why would they do that? How many yellow wires are connected to your graphics card? Are you saying that one wire would be sufficient? As you say, the wires all go to the same pad for any given color. There is maximum current potential at that spot. To assume that each of those wires can carry the full load is absurd. For any given current capacity there is a corresponding gauge of wire that is required to carry that full load safely, all by itself. You need at least that size by adding a number of individual wires. That is the only way to carry the max current available using those wires. Usually it's just a few. The only thing wrong in what he wrote, is the amount of wires that you'd need. Definitely not all. On the other hand, if what you are saying is correct, why is it that there are usually only two 12V rails on an average, modern PSU, and yet there are more than 2 yellow wires going to your graphics card? Because 2 yellow wires are just not enough. That's why. Now if you're still reading this extremely long comment, it means you care. If you care, you should do the math.

[@mgsamps]

Robert, I think you misunderstand my point, as I already stated "(the extra wires of the same colour) are used to power other parts of the computer like multiple HDDs etc" if they didn't then as I pointed out each single wire would not be enough to cope with the load. BUT if you took a single yellow wire for example and were stupid enough to try and draw the maximum rating of that psu by using a clamp meter it would still read close to the maximum amperage rating but overload the single wire. So boowonder is correct in grouping all the wires together to SAFELY draw the max current but implied you wouldn't get the max current by using a single wire, and that also implies that each same colour wire was using separate circuits on the psu which it doesn't in most cases. hope we've cleared that up.

thats extremly amaizing but i watched other videos (this the best thow hh) on how to transform a psu to a lab bench but they used all the wires from the same voltage level not only one as you did and they also put something called dommyload its just a resistor of 5ohm between the 5v and gnd they said its just to stabilaise the psu ,so do i really need to use all the wires and use this 5ohm and thnks.

[@clueless3891]

From someones blog - If you want to get the most power out of your 12V cables (for your extruder nozzle, motors and especially your heatbed for 3D printing), you have to draw some current from the 5V wires as well. Stupid, but that’s how the ATX is designed. With 4R7 Ohm 10 Watt wire-wound resistor result is from an unloaded voltage of 11.65 from my 12 volt connectors without the load resistor, I’ve now got 12.5 volts unloaded. More importantly, with my nozzle and heatbed both running, the 12 volt lines now stay closer to 12 volts. With less voltage drop I’ve got more power going to the nozzle and heatbed, so they heat up faster.
