    Power Setup W/ Laptop and K301

    OK I have my K301 monitor and i plan on powering that normally through the car since its designed for that. I'm going to power the laptop off of a targus DC-DC powersupply hardwired into the car. (I think I'l just use a momentary switch to the power switch, no Auto stuff till later)

    If I am ONLY powering a USB hub off of an OPUS 15w POL DC-DC will this work? Connected to the hub will be the TS, GPS, Wireless(maybe depending on what signal i get onthe laptops builtin), Sound(just a thumb stick), then i will have an acccessory outlet or two on the dash for a thumb drive or other device.

    Is there a better solution to get 5v's for my hub that doesn't cost $80 to $100

    (i've read the 10 page thread on the OPUS but it talked all about screens and my screen is seperately powered by the car)

    I'd like to know the answer to that myself. I'm planning to use the Sony UX-90 as my car pc (driven by a 12v adapter), so all I really need is 5 volts and a few amps for the USB hub.

    There are MANY options to power a USB hub, depends on how good you are with building it yourself.

    Each device, under the USB spec, can take a max of 500ma. So, if the OPUS supplies 15 watts, at 5 volts, that is 3 amps. So, 6 devices MAX can technically be powered by the POL, assuming they all take the max, WHICH THEY DON'T, so it is probably MORE THAN 6 devices.

    This is the type of question is posted OVER AND OVER.

    Please search, since there are OTHER options besides the POL that have been posted.

    The math makes sense thank you for the conversion. It looks like this would work for me. However I would like to find some more options.

    I did search, and I wasn't finding any clear advice as to how to power my hub alone, w/o TS's and hard drives etc... I know this type of question is posted alot, but I could not find the answer to this question after a resonable amount of searching.

    I am a newb to this forum, but not forums in general, so don't treat me like a complete moron.

    Instead of taking the time to be an asshat maybe give me a search string that might have some answers or maybe even a link. If you don't have time to do that don't reply, and maybe I'll find the answer on my own.

    Cause I am not your personal assistant, and since I bill more then you can afford, I gave you the RIGHT advice, SEARCH. Just cause you are incapable of properly accomplishing the advice is your problem, not mine or the people ont eh forum. Your questions shows you did not search, even though yoou claim you did.

    If you didn't want to answer the question, why didn't you simply remain silent? That would have saved a few minutes of your valuable time.

    Hey Noob, notice I GAVE HIM THE DAMN ANSWER, and advised him he should search some for more options.

    Once again, I am NOT A PERSONAL ASSISTANT. Just because the advice means that the OP needs to search, or do more work, isn't an indication that I DID NOT HELP HIM.

    Now, if someone "nicer" then me wants to give him the OP all the answers, that is fine. The fact remains, I have been the ONLY one to offer the guy ANY help.

    So smartass, where is your advice?

    OUSilver05, I think I've found a good candidate. Take a look at this link. It's not clear to me why the 10 amp unit is cheaper than the 5 amp unit, but neither are very expensive.

    Here's a 3 amp version and an alternative source for the 5 amp.

    Here's another thread that helps.

    FAQ: Will <insert PSU model> Power Supply work with my system?

    The picoPSU looks like it would be a better option than the Meanwell since it will survive cranking down to 6V, while the Meanwell needs at least 9V. Or so it seems...
