If Johnny wants to eat two apples, he's only going to eat two whether you put 2, 3, 5, or 20 apples on the table. The size of the wire required even for a small amplifier is still something like 4 or 5 times bigger in diameter.

It might be partly due to the fact that Lastly, im sure you know how to connect your amplifier to your subwoofer but you need to know how to connect it to your stereo. Man.

Psu Amperage Calculator

if u have 30A fuses then u need a PSU of 360W or more (12V x 30A = 360W), so if you have 2 of those amps you need 720W or This generally means they can run from 90-240 V AC, and that can be 50 or 60 Hz. You really don't want to just use two of the original wires from the power supply. it wont blow op :D

    Correct, a switch-mode power supply will need a load to operate properly.

  • Some level of too much voltage will damage something, but you don't know where that level is.

These contain additional circuitry that can tweak the output voltage up and down. An amp is an ampere, which is a measure of electrical current. It draws power from only the +12v rail from your PSU. Psu Rails up vote 7 down vote favorite 2 How many amps on the 12V rail does the motherboard, CPU, and RAM use?

Car stereo equipment can surpass the sonic clarity of home systems...lower total harmonic distortion. How Many Amps Does A 750 Watt Power Supply Use But couldn't find a power supply/adapter powerful enough for the job.. Model (Rated Output) 145W 200W 235W 250W 275W 300W 350W 400W 425W 475W +3.3 V   14 13 13 14 14 28 40 40 45 +5 V 18 22 22 25 Having a +12V current rating that makes up more than 80% of the PSU's wattage rating does not make it a higher wattage power supply.

So when V goes down, I goes down and as a result, P goes down. Can I Use A Power Supply With Higher Amps I don't know if i was lucky or good building it.

I made it using an old power supply. If it had been 22 A, the PSU would be fried! Why is the issuer certificate different at my workplace and at home?

I shop carefully and have read the guides on the topic here on this site. Voltages? Psu Amperage Calculator I beleive you are incorrect because: (believe is the keyword) All multi-rail psu's are measured one rail at a time therefore (the loadsplitters don;t do a perfect job) you get bloated Computer Power Supply 12v Amps If you raise volts, then amps diminish, thus you have less heat...

But when I asked if I must connect the yellow and black wires together (Like you did) on Yahoo Answers, people told me I will blow my amp and PCU if http://olivettipc.com/power-supply/power-supply-calculator-corsair.html Voltage/Watts/Amps? by Jedson3614 › In Win 509 ROG Gaming eATX by khaosgamer › NZXT S340 Mid Tower Cases CA-S340W-B1 Glossy Black by AyyMD › ViewSonic VX2757-MHD 27-inch 1080p Gaming Monitor with 2ms, They have overload protection built right in, and even a 500W model can be reasonably priced with high efficiency. Computer Power Supply Amps

Same goes for 'old magnetic' vs. 'SMPS' and 'ripple'. It's usually labeled right on the power supply. For example, a 12 volt 2 amp supply with a minimum load requirement of 10% isn't guaranteed to work right unless you load it with at least 200 mA. check over here While I'm reasonably sure that there isn't enough residual energy to stop your heart, those capacitors can still bite, ... 2 Step 2: Opening UpOpen the PSU and make an assessment

It could simply blow a fuse. Amps Vs Watts I assume I could still do this using a 4-ch amp with two wired together for the sub? For example a GPU needs a 1,4 V input, before the current reaches the GPU of VGA, powerful resistors block the way with resistance of something like 600 ohms or more..

Car audio stuff is dirty noisy has poor sonic accuracy and this is a super inefficient way to makes some noise.

No video card ever needs a 1.4v input. Now you need to find a way to attach a bundle of wires to a small terminal on your amp. I knew about increasing voltage because of "stun guns". Volts Amps Watts If you're suspecting the PSU to be a reason of unstability, attaching an oscilloscope to the individual voltage rails and watching for voltage fluctuation under different loads is a much better

Your configuration isn't power hungry, since the main 12V rail users are VGA at first place (which is not the problem in your case since you are using the integrated one)
