Vid55 Converting a PC Power Supply to a HHO Lab Power Supply

[rabaduej]

if you utilize all/most the wires you can make a 5v, 7v, 10v, 12v, 17v, 24v and possibly more depending on the supply. this is done using the following. -5v and +5v makes 10V, -12v and +12v makes 24v, +5v and +12v makes 7v, -5v and +12v makes 17v and so on and so forth.

as for the circuit breaker most cpu power supplies wont need one. their circuitry is designed to automatically shut off when too much amperage is pulled through.

other than that good video.

i would think having the 5.5 and 3.3 rails would be most useful if you are building a test power supply. i would just get some bullet jacks or those spring loaded jobs you find on amplifiers and mount them right in the psu case. that would make it so much cleaner of a setup.

[rabaduej]

@conatuslife thats what i did. as for the 3.3 bus i would say no. drawing too much from that can damage controlling circuitry within the power supply. however on mine i use -5v, +5v, -12v and +12v and this gives you a very good range of voltage to play around with. see my comment above to see what you can get out of these babies.

@joopee01 I had a similar problem before.  When I had this issue, I accidentally had a dark blue wire mixed in with the black wires.

If this is not the problem, be sure you do not have any bare wires that are touching any components, wires or the metal housing. It sounds like you have a short somewhere.

[ciprianwiner]

hey thanks a lot man, i blew up an old power supply because of a short circuit so i wanted to put a light bulb in series with the load but that good for loads of max 3A so thanks for the tip with the circuit breaker:)

[rabaduej]

@ciprianwiner it strikes me od that a CPU power supply blew from a short. most of all that i have converted have automatic shut off. no circuit breaker should be needed.

[HHO4ALL]

@rabaduej I use the circuit breaker as a safety precaution, because most of the power supplies I've used were pulled from very old computers. They would automatically shut-off when a short occurred, but when this happens over and over again in a small amount of time, the capacitors begin to bulge and pop from overheating. With the circuit breaker, I don't have that issue any more. I like using what I have, because I don't have a budget for this hobby.

[MrTranxistor]

"stupid little nub thing" it helps if you know what your talking about before you profess in it. it's called a grommet

[HHO4ALL]

@MrTranxistor

Does it matter what it is called? NO! 

Does it effect the outcome of converting a PC Power Supply to an HHO Lab Power Supply? NO

Does anyone really care that you took the time to point this out? NO

[askaboutRudyV]

@HHO4ALL HAhaha, you tell'im Chuck.

[alexwbenel]

@HHO4ALL I know this might sound stupid but what is a "connector" and where do I get the one you have?

[HHO4ALL]

@alexwbenel A Quick Connect Terminal. They come in Female and Male connectors and can be purchased at most hardware stores. I get mine from Home Depot.

[alexwbenel]

@HHO4ALL Do I just connect the quick connect to alligator clips?

[HHO4ALL]

@alexwbenel you could just use alligator clips at the ends of the wires. That might be easier.

Hey I just built this it works great. I'm somewhat confused because it says 400 watts on the package but seems like it's top operating power is 300 watts because 12 volts x 26 amps is 312 watts. I don't really know, However the power supply works great!

[HHO4ALL]

@legogunguy001

It is 400 Watts, you also have to include the 3.5V and 5V amperages.

[legogunguy001]

@HHO4ALL Oh ok Thanks just ordered a circuit breaker.

[frosty1433]

@HHO4ALL I don't know much about this type of thing yet, but I hear the red wire actually carries more amperage than the yellow. I wonder, is it possible to connect the red and yellow in a parallel fashion?

[rabaduej]

@frosty1433 no sorry, i believe the red is +5v and that's why the amperage is higher. if you connected +5 v to +12 v you would get a short. the difference between the two is 7v. so your basically shorting out a 7v potential difference.

nice vid.

I had no luck with comp psu's...switched to a secondary rewound MOT (which adds a whole set of new "problems") but, it would be interesting to to see how long this psu lasts you.

[rabaduej]

@bananaphonehome i have converted 9 power supplies. all of them are still working with no problems. however i only use 2 of them everyday. the 1 that i use everyday is over a year old.

[fuelityourself]

Nice W ork young man! Your Video is the rpitomy of what most if us science guys/ researchers are looking for.

[HHO4ALL]

@fuelityourself

Thank you, I'm glad to hear others find this information useful.

We all have to share our discoveries so we can advance this technology and make it available to the general public.

[97bosko]

great tutorial i've done this about 2 weeks ago but i left the orange and the red wires out and i have 3.3 volts @ 36A,5 volts @ 40A and 12 volts @ 21A.By the way it's a 300watt power supply.

[fuelban]

Hi HHO, see the nub thing you call it, the rubber circle, its called a Colet in the UK, but what I want to let you know, is I have used these on holes guy ,in my plates and cups, you pop them on to holes and pass bolts through, to isolate the metal, or in gas exhaust holes, pop them on to stop plate electric seepages, handy to know {good video HHO].

Thanks.

Thom.

THANK YOU SIR ......

Very nice info, thank you. Shrink wrap is very handy as well. ; )

great tutorial

[HHO4ALL]

@patricksab

Thank you

[HHOButterSkate]

i did this to mine. worked perfectly!

[crazyFLkid]

sweet dude! I was wondering how I could get a good power supply for mine...cheaply...
