| Re: how to use pc power supply for 12v uh, fosgate, your wasting your time, I ran two 300 watt pioneers in my pickup with two 2 farad caps on 60amp fuses and I fried the fuses on more than one occassion. Car audio is one thing, where you never reallly need to use more than about 50 watts where you aren't likely to use more than 10 amps at the peak with the whole system, compared to my pro audio system that draws over 160 amps from the bank of sub batteries yet still manages to pound with 16 guage wire from an outdoor outlet. I've pullled over 2,000 watts peak from a single outlet and have never blown a fuse or tripped a breaker, and being a licensed electricitian, I can tell you that that is about the limit. Above all else I'm an amatuer radio efficianato, and I've used PS's to power amps, and you will likely need at least a 15 amper to cover what you want to do, if you have all the wires from a pc PS tied together, theoretically it should do the job, but a few "lightening caps" sure wouldn't hurt.
My entire system is powered off a bank of solar panels that charge an array of sub batts that runs at 24 volts and then is re-converted to 120v ac pure sine wave, which produces a lot of heat in the basement. Mostly the power from the solar cells, and batteries powers our dryer since we have 16 people living in our house, but for the most part, it works pretty good, our electric bill is less than 300/month. Come July, it'll actually be lower even with the higher temps in ND, but with more solar hours the batt's charge more that they get discharged, even running the 6 AC units. |
