Hi Great Video i have actually done this project my self and something i found thats good is if you draw to much current from them they normally shut off automatically before they damage them selves. another power source i used was the LED power kits you can buy off Ebay as they actually have a variable voltage from 10-14.5 volts which is super useful however they dont protect them selves so you have to be careful you dont draw to much current from them havent killed one my self yet but i have had one get pretty warm

Good work To protect the ATX again short circuit. It will be better to connect the Green wire (power on) to Relay contact with black wire. And to energize the relay with the 12 v or 5 v accorditly.

Du weist schon das PC Netzteile Schaltnetzteile sind oder? Die sind für die Dauerlast einer Endstufe nicht ausgelegt, folglich dessen reagieren Schutzeinrichtungen auch nicht immer und das Ding falckelt schneller ab als Du geiler Sound sagen kannst. Die Endstufe die du dran hängst wird eh nicht mehr als stabile 20 Watt rausgehen, weil die Spannung von Anfang an schon zu gering ist. Wenn man 50 Euro für ein Netzteil und 50 Euro für eine Endstufe ausgehen hat, plus Kleinteile ist das für 20 Watt rausgeschmissenes Geld. Davon bekommt man ne t.amp e400. Die leistet locker 10 mal mehr als die 20 Watt die bei dem Pfusch rauskommen. Strom ist Lebenslänglich!

The problem with cheap computer PSUs is that 12V output depends on the load on 5V rail. If there's no load, you will get a very soft 12V rail - voltage will quickly decrease with any load. To get the most out of a PSU like this, you need to put a solid load on the 5V rail. It's a different story with modern PSUs that get 5V and 3,3V output from a 12V rail and will allow you to drain full power from the 12V rail (that's also how you know it's this kind of power supply - max output on a 12V rail will be the same as a total max output).

Tomas Kuruc I just bought a thermaltake sp-850m for a jl360/2. Amp uses a 50amp fuse. The psu is 70a/840watt on single 12v. Would I still need a dummy load on the 5v and 3.3. I purposely got a bigger psu that is also an 80plus bronze to help with heat and efficiency as I need this amp to run at least at 80% load,bridged which will be between 280-360 watts. And this needs to run for a minimum of 5hrs at this load. So I know the basics which is adding all yellow, black and putting green/black. Now what I need help with is efficiency, and stable load. So if that requires dummy resisters etc and where, please shed light or find me a video of someone doing exactly this cause all these video sick cause they never show the system working or if they do, at what volume to let me know it's stable
@tomkocur6 жыл бұрын
that all depends, check the actual voltage on 12V rail while the amp is in load, if it doesn't fall below 11,5V, you're all good, if it does, just connect a couple of car bulbs (in parallel) to the 5V rail (red). That PSU has a strong 12V rail and is quite modern, so it might not even have the type of regulation that's used on cheap PSUs.

watts = amps x volts. The chart on the side of the power supply, the one the video shows, has the watts listed for each of the rails, and a maximum overall wattage. Divide that wattage by 12 and you got your amps. Use the proper sized wire for that amperage if you use a junction block, and I wouldn't use a cheap or exceptionally long power cable or extension cord.

and you can run these supplys together to get as much volts as you need. if you hook the blue off of #1 supply and the yellow off #2 supply together then come off of the blue and yellow thats left not used you will get 48 volts. hook 3 supplys together get even more
@videomaker8116 жыл бұрын
No u wrong. Please learn electronic. The voltage is still the same just increase the current. But u can't combine all of them cause it have different current output. If u device draw more current then the one with lower current output will burn the ic inside the psu.

Generally .. SUV batteries are 80-90 Ah - 12V . 12 x 80 = 960 watts.There is no problem . If we connect it in to a heavy truck battery (150 Ah ) 150Ah x 12v =1800w there is also no problem with the car audio we know ! In my point of view computer power supply output which we are using is a pure DC as like from battery source. So no need to panic..!
@Pirmy767 жыл бұрын
I think you should learn the difference between A and Ah. Saying that a 80 Ah battery is 960W is... well totall nonsense. The 80Ah battery specification meand that the battery has 80Ah capacity. It means that a battery can supply 80A for one hour. Example: if you have a device that uses 10A 12V (120W), the battery will be dead in 8 hours. If you have a device that uses 40A 12V (480W) then the battery will be dead in 2 hours. Calculating Ah x V is.. nonsense.

lyrics dj well I think I'm going to use a car battery that's hookt up to a PSU and from battery to amp. Because some amplifiers draw just to much amps for a PSU at a few seconds (when the bass drops) and that's when it's good to have a battery also connected to the amplifier. and when I'm not playing and have everything turnt off then you should of course not charge the battery with a PSU cuz it WILL overcharge the battery. So buy a 12v battery charger that's ONLY connected when the hole system is off, so the battery is ready at 12v when you want to play, and have the PSU on while playing music so you don't have to turn down and charge after a while of playing. hoped this helped you.

@karlmagnuson7374 жыл бұрын
Your power supply should have at least 150w of headroom more than your amplifier. Your subwoofer works at low volume because you aren't asking much from the power supply, but once you give it a higher load the thing craps out because it is no where near powerful enough to support your amplifier.
@jamesgoodacre23054 жыл бұрын
Hi, your amp in the real world won't be putting out 2500 watt. You need to know the rms wattage.that usually will be quite a bit lower. Also you need to make sure that any psu you use has adequate amp rating which is the same or better still slightly higher than your amplifier. Check this by simply checking fuses on you amplifier. I would have thought a psu of say 750w minimum with a amp rating of say 60amp would be plenty powerful enough.

mine only puts out 11.4 volts but that will still run 12 volt items - you dont need exactly 12 volts to run 12 volt items - to charge a 12 volt battery to full capacity you need to charge over 12 volts - most cars charge at a max of 14 to 15 volts - anythinig over that things start to fry - ive seen over 18 volts being thrown out of an alternator - thats bad .... charging at a capacity of 10 amps is good - 2 amp to 5 are most trickle wall chargers for batteries.

Please help me. is it dangerous to use a power supply that give less power than what the amplifier draw ? I have a crappy pc atx rated as 12.4 = 7.5 Am ( 220 Watts total ) . but my car amplifier is probably 250-500 watts and 40-50 Am

mehdi Moro there is a key difference between power ratings in car audio and computer components. In computer applications, the psu you own will put out 220w, maybe 250w MAX to give some headroom in the event of power spike. In audio applications power is measured in rms or root mean squared. You should look up the difference between measuring at peak and rms, but if you tried driving your amp with that psu you would blow it up before you get to half volume.

A good rule to follow when re-using a pc power supply, Look at the AMPS Fuses. You need at least this much amperage on the Power Supply 12V rail(s). For example : If you AMP has 2 x 20A fuses you should at least have 40A of power on the 12V rails. If you had say 42A on your Power supply, It would work but I would not run it hard for very long as the power supply will not last very long pulling max. amps. It would be better to have 50% or more amps to spare. I think doing this will end in tears in days to months as best. Better to just buy a fosi audio BL10C AMP for $45.

yes :) it would be disaster if you put 12 volt on 5 volt device
