Is there any way I can power this load?
I plan on building an mp3 box with the following components. I was told that it would be impossible to power all this, and I would like to get a second opinion.
micro atx motherboard
20gb udma hard drive
6x dvd drive
matrox g200 video card
soundblaster platinum sound card
5" parts express lcd
Would you suggest an inverter or a dcdc power supply for the following setup? Also, what options do I have as far as reliable dcdc power supplies that are compatible with atx cases? Any comments are greatly appreciated! Thanks!
Currently your only practical option is an inverter supplying a regular ATX power supply. There is no reasonably priced DC-DC available to power such a system
So a 250 watt DCDC power supply (http://www.casedepot.com/index.cfm?do=DetailView&ProductID=222) won't work? Thanks!
You'd better first work out how much the peak and sustained current is.
You might consider adding a second battery, and probably replace the dynamo with one that can handle the extra charge current.
Also consider using less power consuming parts, such as an industrial Single Board Computer. Check www.advantech.com !
BTW, I'm building a DC-DC PSU that can supply +5V @ 10A, +12V @ 3A, -12V @3A. It can done!
