Superb conversion of computer ps to bench ps. Kudos and post such videos.

cool....nice mix power supply for everything needed

Vielen Dank für die ausführliche Erklärung und diesen schönen Schaltplan

Brilliant - the circuit diagram says it all and the video is very good and self explanatory.

I find it curious that people who are on KZread watching videos on making a light-duty, benchtop power supply from an ATX PS (not your everyday project for your everyday KZread user, after all) are bitching about the music rather than muting their sound. If you can't figure that out, people, perhaps playing around with sharp and/or hot objects is probably not for you. Well done, RF.Odel. Thanks for your efforts.

You apparently wired your rocker switch backward. 1 is on, 0 is off. It looks like you pressed the 0 to turn it on. If it works, I guess it's ok, but someone may plug it in thinking it's turned OFF when it's actually in the ON position. Also, FWIW, it would have been much better if you had replaced the cheesy music with some narrative explaining what you are doing, and why, as you move through the conversion, for the novice tech who is trying to duplicate the project. Yeah, it's about as simple a project as it gets, but a little dialog would have taught a lot to those that are new to this kind of thing.

great presentation thanks and God Bless : )

This is a simple yet neat design, but four wires for the 12v rail are way too much, anyway it depends on the power delivered by the single rail. For example, if you have a 18AWG wire, it can deliver an ideal 16A of current, tuned down to 10A to be safe. If the 12V rail can deliver a maximum of 20A two wires might be enough to meet the power limits of the PSU - and by the way, small electronic projects for beginners rarely take so much current. The same rationale could be applied to the other rails. Usually the -12V and -5V (if you have it) gives a fraction of amp, so you will never see more than a single wire from the board for each of them. An overall classic for a beginners project. It teaches an enormous amount of stuff about electronics.

Why that 5 ohms dummy load is necessary? I think is 1A running there, could be 50 ohms or even 100 ohms?

Well done 🥇how many the resistor? Thanks

You already know that the "-12V" connection delivers only a few milliamperes? The -12V connector was needed by older sound cards to produce a balanced output signal. In today's power supplies you will hardly find -12V or not at all, because it is unnecessary.

Most power supplies wont need the 10W resistor on the 5V rail and the green and black power wire should be a 10K resistor instead since most supplies have a mains power switch that should be used in this case. - Reference: playtool

@gaylephillips8813

Hi Mywindow, I didn't see a mains switch on his PSU. I've got a Dell PS-5201-7D ATX PSU that I'm planning to use for a similar supply, and it doesn't have a mains switch either. I think I'm going to mount the PSU box to a board, add a master (mains) power switch, and maybe add a front panel on which to mount the binding posts and LEDs (maybe a Chinese digital volt / current panel-mount meter, too), just to stay well away from the big transformer that sits just behind that grill where he mounted his components. No sense tempting Mr. Murphy!

Does no-one else see the bulging capacitors on the side of the main board where all the voltage wires are connected? I'm not sure if it would support extended use. Though that's not likely the intended use for this project, bulging caps just make my spidey sense tingle in general

Excellent and didactic video. I made the same ATX converting power supply following your diagram and adding an step-up booster to increment the 12v to 18v which support 15 A, in order to connect an drill. It works but the problem its the dummy load resistor overheats (it is a 5 wats but 9 ohms; the only i found in my store). Is that the cause of the overheating? Thanks for your aid.

Not too terribly. I did the same thing with my old PSM. I would just advise maybe adding a secondary cooling fan on the outside of the box to help the main fan keep up with the added air flow restriction. It works a treat. Mine now has no problem keeping up with any amount of high power draw. A simple fix.

Nice simple, useful conversion, thanks. But your soldering techniques leave a lot to be desired. They will result in cold solder joints, increasing the resistance of the connection, reduced current. voltage drop, and the potential for a broken connection. Sorry.

Thierry ON Well 5 ohms is used to ensure a steady 1 amp load on the 5v rail but if you have two 10 ohm resistors you can put them in parallel to get 5 ohms and make sure it still has a 1 amp load. The dummy load requirement varies by power supply and some might not require it at all.

Step 4. install components. What components? Where's the list?

As a general rule, how many Amps can someone expect to get through (or out of) the 12v terminal using a 550 watt power supply, assuming that ALL 12v wires are soldered together? In other words, how many amps will most 550 watt power supplies provide.

You have fallen into a common trap. Unregulated power supplies can be several volts higher than what's on the label. When you put the power supply under load, the voltage will say to be roughly then rating on the label.

@dalexplym4882

There is no voltage rating for LEDS, although the internal voltage drop varies a little, depending on the color. The only concern is current (should be less than 20 ma.) so any resistor between 220 and 470 ohms will work fine. If you want an indicator on the 12V lines, use 470 - 1,000 ohms. Be aware that LEDS are polarized, and will not turn on if connected in the wrong direction. The flat edge (cathode) should face the ground (or negative) connection.

Do you have a component listing / name and using a 110v instead of the 220v shown?

@josephsvensson6637

If you have a 110 supply and 110 mains voltage the only thing you would need to change might be the switch used to break the mains connection, but if it can handle 10A at 110v you should be fine.
