    very confused about power

    okay i have been reading these forums for the last month or so and i am very confused about the whole power siuation for a carpc

    i dont know what an inverter does, what a sproggy does, how to connect it to the battery or anything.

    can someone please explain the different parts for me and possibly make a graph of where the elctricity travels from one point to another?

    i cant wait to connect my comp to my car but i just dont know how to get power to it.

    your normal PSU in your computer takes in AC power from the wall and converts it into dc power which your motherboard and other parts need. Now a sproggy and a opus take the 12v dc power from your car and regulate it and split it into the type of 12v and 5v power your motherboard needs. WHy is that better.. it doesn't cause noise int he system and its quiet. There are many other advantages though.

    With an inverter you are taking the 12v power from your car changing it into AC power then it goes into your PSU and switches it back to DC. That can add noise in the speakers and heat. The reason people do it that way is to save some money.

    If you use a dc-dc PSU you don't need a normal PC power supply

    well which dc-dc psus do you guys reccomend?

    how much more money is the dc-dc solution rather than the dc-ac power route.

    a lot will recommend the opus.

    An opus will run around 200 for the 150 watt version. The cost of the inverter+normal PSU is the cost of the PSU (usually included in the case) and the inverter. Around 50-70 at normal stores for a 300 watt version. You want to use a higher watt inverter then your PSU if you got that route

    - DC-DC units are more efficent than an Inverter and typically will allow your CarPC to continue operation during cranking. These Units include the Opus, Keypower, Arise ACE-865V, and Arise ACE-916V
    refering to Frequently Asked Questions

    i'd say the majority of the users around here use to Opus power supplies because of the features they have and such.

    cheers and good luck

    I paid $40 for my 400watt inverter and the power supply came with the case so it can be quite a bit cheaper than dc-dc. I haven't had any problems with noise or heat yet, but I haven't been using it all that long yet. eventually if I have money to burn I may go with an opus, but it kinda seems like a waste.
