    is this too much for my dsatx PSU?

    Right now I have:

    1 7200 IDE drive
    1 sempron AM2 3600
    4 usb devices - gps/wireless network/xenarc/mouse
    1 512 f2-6400 ram


    I ran this through an online calculator and it came up with 153W.


    I was at Walmart tonight and got 2 cigarette lighter style power adapters. I was going to wire them up to a standard PC power dongle and plug them in so and put 1) Xenarc and 2) my radar detector. This way they both turn on when the truck is on.


    Is there any forseen problems with doing this?

    also....



    I just put a multimeter on a PC power line. There's 4 wires that come out of it.

    1 yellow
    2 black
    3 black
    4 red



    it looks like yellow is 12v and red is 5v. would I want to wire the adapter up to numbers 1 and (2 or 3)?

    You'll be fine, with room to spare.

    What is a "standard PC power dongle"?
    Are you going to power the Xenarc and the radar detector from the DSATX?

    Are you talking about the cigarette lighter adapters you purchased?

    Both the Xenarc and the radar detector are designed to be run straight from the car's electrical system. As such, I recommend wiring both directly to the battery. If you don't have to power something with the PC power supply, then don't do it.
    There's no point in taxing the DSATX any more than is absolutely necessary.

    That said, you probably have ample headroom on the 12v line from your DSATX to power it all if you choose. It's just unnecessary.
    Have you looked in the FAQ yet?
    How about the Wiki?

    I was thinking I wanted to go through the dsatx for 2 reasons. Maybe I'm thinking the wrong way though! so tell me if i am.


    reason #1: Reading this board, a lot of people still recommend running the xenarc off of the dsatx because it's extra protection from spikes which means longer lasting monitor over time.


    reason #2: I want both the radar detector and the xenarc monitor to automatically turn on when i turn the truck on, without taking up the factory cig lighter. These 2 things are now permanant parts of my truck. seems very tacky to me to leave them in a cig lighter spot. So the dsatx was the next logical decision for me.

    How are you connecting the radar detector to ur truck? By dsatx?

    I don't think it's a matter of "right" or "wrong", but a matter of opinion and how to achieve the desired result.

    reason #1: Reading this board, a lot of people still recommend running the xenarc off of the dsatx because it's extra protection from spikes which means longer lasting monitor over time.
    I don't buy into that, although the logic makes sense.
    The whole point of the internal regulation on teh Xenarc is so that you can supply it the "dirty" power straight from the car's electrical system. That's what it's designed to do, so why not use it that way?

    reason #2: I want both the radar detector and the xenarc monitor to automatically turn on when i turn the truck on, without taking up the factory cig lighter. These 2 things are now permanant parts of my truck. seems very tacky to me to leave them in a cig lighter spot. So the dsatx was the next logical decision for me.
    So don't take up the factory cigarette lighter. There are other sources of IGN-controlled power besides the cigarette lighter. I merely posed that as one example. Most fuze boxes have unused spots where you could create your own circuit. They're already controlled by the ignition, so all you need to do is wire stuff to the fuse holder, put in a fuse and away you go.

    Don't get me wrong. The DSATX is a great PSU. I have one and absolutely love it, particularly the ability to program it to behave the way I want. I don't think you'd have any problems powering everything the way you suggest with the DSATX.
    I firmly believe that you should use the computer PSU to power only what is absolutely necessary. Devices that have the ability to run straight from the car's electrical system should be powered by the car's electrical system, saving the power from the DSATX to run what it needs to.
