Reply With QuoteWhy a P1900 and an M2ATX?
Based on your setup, I don't think you'd need both, only the M2ATX.
Ok, heres my current planned pc. A mATX mobo with an Athalon X2 3800+ (of course the ultra low power 35 watt max under full load), 1 gb ddr 2, mobile 5400 RPM hd, DVD reader, and a USB hub. The mobo has 4 usb (2 on backplane, and 2 on a header that im gonna use to put an easy access usb ports), which covers the basics. The reason for the hub, is because I could use up to 7 usb devices. The usb devices im gonna use are: Audigy 2 external sound, GPS, OBD-2 reader, Bluetooth, Wifi, Keyboard and mouse (only hooked up occassionally, for easier surfing the net, such like that).
Im looking to power it with a Carnetix 1900 PSU, and m2 ATX. Im unsure about weather I want a slide out LCD or just a front facing one, but either way the carnetix 1900 will power it.
As far as power goes, this is how it's suppossed to be setup correct? Other then that anybody see any flaws, or does it seem pretty well laid out? (yes I know everybody's needs/wants are different, but just wondering if that looks like it'll work fine from the ppl that have done car pc's)
ok so 2 questions
first: I only need the m2-atx, and NOT the 1900 if i go with a mATX mobo. If I go with the Aopen pandora, or another mini-itx, the 1900 would be btr, and connect it with a barrel connection.
second: I might need additional power rails (i.e. for the monitor, etc), and if so can I hook 2 up simultaneously? of course on their own dedicated cableing to the battery, but would it work?
Third: If I needed additional power would I be btr of to use 2 m2-atx OR another psu?
If you choose either model for the applications you listed, you can still have a 12v connection for the screen in addition to the PC. The P1900 has an additional connector with user-selectable voltage specifically for this purpose.
i wasnt able to find info about how many 12V connections were on the m2atx
looked for quite some time with no answer lol
you can always splice into the molex connectors, it doesnt matter how many connections there are, it depends on the amperage of all devices running off of those connections, and what the power supply is capable of outputting
Its not the amount of connections that matter, it's the current that connections are pulling that matters.Originally Posted by BDVirus
Think of it like your house outlets, You could have like a 100 sets of christmas lights hooked up to one circuit and be fine. Now uplug the lights abd try hooking up 2 air conditioners up to the same circuit and see how long they run before the breaker pops.
Hell, think about your battery. There is several hunded devices all hooked up to that one battery....
