I am planning out my car computer and need some advice on power supply. I will need to power an Asus nForce2 Motherboard (onboard video/sound/lan), Athlon 2000+, 7200RPM 80gb 3.5" harddrive, desktop dvd-rom drive, 4 fans, and some miscellaneous USB devices.
From what I've read it seems I have 3 main options:
A) Use the Opus 150W DC->DC power supply. This costs about $200
B) Use this 250W DC->DC power supply: http://www.orbitmicro.com/products/p...2/KPDX250H.htm $180
C) Use an inverter plus a regular ATX power supply. If I go this route I was thinking of getting the Coleman PowerMate 400/800 inverter.
I have a few questions:
1) Will the Opus 150W be enough power to run all my equipment. The guy at my local computer shop (who is fairly knowledgable) doesn't think it will be enough power.
2) If I go option B or C I will need a separate shutdown/startup controller correct? I believe the Opus has one built-in. If so I was looking at this one: http://www.soltronixstore.com/Detail.bok?no=7 Has anybody used this before or know of any issues I should be aware of?
3) Has anybody used the Coleman PowerMate Inverter before? Are there any issues I should be aware of?
4) Will all the options survive cranking without rebooting the computer?
Option A is $200
Option B is $180 + $30 for shutdown controller
Option C is $30 off eBay + $30 for shutdown controller + $25 for regular PSU
Option B is only $10 more than the Opus and seems to be a better choice seeing how it puts out 100W more.
Option C is less than half the price of options A or B, provides up to 400W of power, and the only downside I know of is its less efficient. Are there any other pro's/con's I'm overlooking.
