Hi Guys,

I'm about to build my first CarPC and I'm a bit confused about which PSU I need for it.

It shouldn't be too power hungry, its just the Mobo and a SSD that it needs to power. But it needs a 4pin 12v supply for the CPU in addition to the ATX supply, none of the PSUs I've seen have this second output.

I think I'd go for the 60w CarNetix PSU, but stuck about the wiring.

That said, I have got an 80w PicoPSU that I bought for an earlier attempt, but it doesn't have the SATA connection I need. (Although could use an adapter) - but still doesn't have the secondary 12v input.

Any help would be appreciated

First off, start peusing the FAQs: http://www.mp3car.com/vbulletin/advfaq.php

That board is an ATX-compliant board, so you really need an ATX PSU.
M-series, Opus or DSATX are your options. It all depends on the features you want, your budget and how much space you have available.

But seriously, what he said. I personally have a m2, and it's worked great for me. Definitely get yourself a PSU with a shutdown controller built in.

The m2 still doesn't have the 4 Pin CPU power connector though?



4 Pin, top right between the caps.

Ah, I notice the DSATX has, that's spot on. - Although I don't need 220w! Don't they do a lower power one?

The FAQ doesn't mention the 4 pin CPU power connectors at all btw...

Update - do'h, just noticed the M2 does have the 12v CPU connector as well. Cheers for the help

I presume with a M2, you don't need a power regulator like a P1290 then? You just wire the M2 into the car?

you could use something like this for the 4 pin connector: http://store.mp3car.com/4_Pin_P4_Mol..._p/cbl-056.htm

all atx compliant dc-dc power supplies just need to be connected to the battery-- they will regulate the voltage to the motherboard.
