  • Will the Power Inverter be enough?

    My computer has been running fine in my car but lately I've been getting the urge to add a few things. First I'm adding an external DVD enclosure that runs off of USB. I also added a wireless internet adapter and a wireless keyboard w/ mouse that both run off of USB. I'm sure I'm very limited with what my power supply can dish out to "USB".

    I'm using an M1-ATX. My question is though, I'm going to be adding a power inverter to power a PS2 and I was wondering if I could just get a USB hub that plugs into AC power like the inverter. Then I could run most of the USB devices off of the hub and not the power supply in the computer. Would that work? Darque mentioned adding a POL, but if I'm already getting an inverter wouldn't that work as well?

    This can certainly work. Just make sure the Inverter is powerful enough to handle everything you need... My suggestion is you add up the power requirements of all the devices and then get an inverter with more power than that. This way, in the future, you won't experience the same issue you're having now with expandability.

      Is there a way to calculate the power each USB device is needing? Like I'm looking at my drive that came in and it doesn't say anywhere how much power it consumes.

        Hey kbkid,

        I looked for a minute or two and this is what I was able to come up with.

          Yeah as soon as I posted I found that as well. It doesn't make much sense though. I have a Via M10000 MB, a 2.5 harddrive, a single slim line DVD drive, then I have a wireless adapter for internet, wireless keyboard, touchscreen, an external DVD drive that takes two USB ports and I had planned on getting GPS reciever. So thats 6 USB devices. That is giving me a 41.16 watts? Is that right? My video and sound are both coming from the onboard motherboard.

          Also that is all at idle. If I were to be running Mp3s it would be 47.25 watts. That just doesn't seem like much.

            I would assume its correct, but some others may have actual data if you look around for it. I personally don't have a Via board so I can't tell you. but I'm sure someone will come around to help if you ask the right question.

              Alright I'm assuming a 400 watt inverter would be plenty to just power the USB hub, wouldn't you?

                The USB hub I am thinking about picking up is the D-Link DUB-H7. It appears on the back of the hub, it has a Type B USB port and a power port. The power port says 5V 3A. Can anyone explain this to me. Does that mean the "power adapter" plugs into the wall, as in 120V, like a household outlet. I know this sounds pretty stupid but it doesn't make sense.
