RED is + or VCC, the black is ground - simple mistakes like this can cost highly if not spotted You can buy an ATX supply breakout board for not a lot of cash, plug the PSU in and connect to the FUSED outlets for 12 + / 5v and 3.3 v (depending on your PSU) Look at the label to see the voltages and current limits. Remember the box is metal and most of the connections are open. Don't block ventilation especially when running at high currents (a 250w PSU could deliver 20a at 12v)
The video does not clearly show that one of the "made" cables is made up of all the black wires and the other cable all the yellow wires. It looks like both cables are black wires in each. Should have been made more obvious for those who are new to this.
I guess is a mistake during the video editing. If you have a look at the final multimeter reading (3:55), he gets 12V from the red labeld cable with the red terminal on the multimeter and the same for the negative.
I laughed at this too, but no mistake was made. You can also see his meter probes are reversed, which is why he reads a +V. In the end it doesn't matter as long as you stay consistent.
Hi..ok got mine to work .once i connected a 3ohm 5w resistor from 5v to gnd...the ps now powers on fine with good 12v and 5v output...like somrone said it needs a load to power on and the fan alone is not enough apparently....going to use this os for my 3d printer...
well if red is not 12v plus or positive. Then you have a serious problem as stuff will burn. I suspect a mistake was made ? anyone marking red as ground is wrong, wrong wrong. Good video though despite the error making red one as ground.

great video, how do we find out the total amp output from a PSU like this? in my label marks 2 difrent 12 Amps, 5 volts amp, 3 volts amp, basically two for each
@@ramarro-9104 ok I see it now. It threw me off around the 2:30 mark when he created two separate black strands. Would be wise to mark each strand with electrical tape or some type of marker
Can I just run a line off an unused yellow and black wire to power something 12v 3.6a? Only have one psu and it's in my computer but the 12v 3.6 item I'm trying to power only gets used when my computer is on. Don't want to cut up my current psu.
I have 2 550W PSUs here, the powercase brand one says maximum load is 40A for +12V and a corsair CX550 says 45.8A for the +12V. I have an antec 350W PSU as well and that has 2 +12V rails with maximum current of 18A each.
Yeah different psu differ. I bought PSU rated 1050W from Gamemax... Turns out the real power for 12V only max around 900W or 850W if I'm not mistaken, rest is for the 5V etc. I think that's one marketing strategy, after all it's not so wrong. But 150W is not a small difference, good in this case that 150W less compared to total power is rather unaffecting.
its most likely power overload. because there's no load on the PSU, most of the power goes through earth and kicks out your breaker for safety Or it could be bc you might have a faulty psu
Yes it is but you should need to control its amperes to use for an amplifiere just see how much original power sorce voltage and contral it using dc to dc step down converter which is easily available at online or at shop☺️
I did this with a 600 watt power supply. I call it the ghetto blaster and it is stupid loud! An old Alpine bluetooth car stereo, four 6.5 inch speakers running off of the Alpine stereo and a kicker 400.1 mono amp on an America. Bass 10 inch subwoofer. Hits ridiculously low. Id bet money that the bass hits lower than any bluetooth speaker you can buy at any store, and the mids and highs are loud and clear. Everyone that sees it are absolutely blown away by the sound this thing puts out.
I have a DC pump that I use for pumping oil. so do you think I could use a computer power supply to run it? I figured since it hooks up to my 12v battery that it might work with the 12v power supply. it uses 13.5 amp. ty for your assistance. 🙂
Yes you absolutely could. I have several 12 volt DC pond pumps that control my aquariums and sumps. They are all wired into a PC, with a fan controller. The fan controller allows you to alter the voltage that is being supplied. Typically this would increase or decrease the fans RPM, thus allowing you to control the airflow rate. In my case the fan controller is simply used to open and close pressure valves , in order to control water flow rate. Ensure you use the correct 12 volt connection, as there can be 5 volt and 3 volt as well coming from your PSU
Red = +5vdc // yellow = +12v dc // black = negative . Disregard rest wires except the green as when that's connected to negative it will trigger the unit to power on. Most tax supply should be same. Use a voltmeter to verify it
Amazing! Just Plug in an ATX Power Supply, Short green and black wire and boom! MAGIC! YOU GET VOLTAGE OUTPUT FROM IT! NO ONE IN THE ENTIRE UNIVERSE CAN DO SUCH AN AMAZING JOB LIKE YOU!, I'm literally feeling bad for those idiots who came to this video and didn't knew shorting green and black wire on an ATX Power supply actiavates all voltage outputs, and I'm sure you don't know there's always a 5V Output from the PSU whenever it's plugged in no matter it's on or off, it's called 5V StandBy Power line... I just never understand why so weird videos get soo much attention, literally amazing content is lying like 10-15 views and your video, WOAH WOAH WOAH! I've seen many shitty algoriths, but RUclips, Ohh, Ohh, Ohh! RUclips's really shit when it comes to algorithm and video recommendation
Power is power, you can do it. The only kinds of motors which would be problematic are those which require a very high power spike at startup (like compressors).
Yes, my book often says Red is positive in 12v. I wondered if anyone has used this as a battery charger. Very clever
You don't charge batteries at 12 volts, they are rated at 12 volts but can be anywhere from 14 to 10
I would definitely use this if I didn't need to have a battery float charged at 13.6V

On desktop pc ps...typically yellow is 12v..red is 5v..orange is 3.3v..black gnd
That was freaking awesome
red is positive usually on planet earth.you labeled it ground.you confused me.
Why you just didn't used a male/female connector instead of destroying all the psu wiring?
I'm assuming it's for efficiency and less resistance in the wire

Sir, what is the total amp of Smps after modification.
Hope u will answers.
@3.46 you have mentioned GND as the red wire (Positive) can you please explain why?
because he's an idiot
I was wondering the same thing Red is always power and black is ground in DC.

3.6A for a single yellow/black wire pair is too much, you risk overheating it

Ty again.

How many amps on 12v this outputs?
24 volt cable?
Isn't it necessary to have a load on the 5V rail? This could damage the PSU over time.
Yes it is. Unless if the PSU is never on standby, the PSU will degrade over time. Something like a resistor would prevent this.
Could you explain further
I used this to use a 12v LED strip directly powered by the PSU lol
How?
can i use the 12v molex connector to power my 12v 5a amplifier?
Yes
5 volt driving 12 volt motor at half speed
How many watt ?
When hop?
How many watts it will come in dc
like 240 (depends on psu)

can it run a 12v 30A dc motor ?
You should use atleast 400watt psu at 12V 30A the motor needs 360watts for that reason you should use 400-450 watt psu so you get actual 30A
could this be used to power a radiator fan in my home
