Ok, I wont go into too much details (yet) about my planning, but what it all comes down to is... I need a 500-600 watt power supply for the computer (pretty powerful little machine, yeah).
Now, obviously DC-DC is not an option for me, so I am forced to use an inverter. My question is, how much wattage should I get in an inverter to power [let's say] a 600w PSU? I'm looking at a 1000watt inverter, but is this overkill?
I'm a little slow when it comes to this stuff. I'm a software programmer, not a hardware technician...
*Note, only thing being powered by the inverter will be the PSU.*
*The monitor and everything else will be powered elsewhere.*
*Price is not an issue when it comes to this project.*
Honestly, there is no need for a PC in your ride that requires a 600w PSU.
Most of us (TheLandYacht being a noteable exception) get by with a system that consumes well under 200w.
I dont have a set list of hardware yet, as i've just started planning/research about a week ago. I can, however tell you what I expect out of my PC.
Firstly and most importantly, it must be fast. I've pretty much made up my mind on anything dual-core at 2.0gHz or higher with 1+mb cache and 800mHz fsb. AMD Athlon X2 looks really good to me (socket AM2).
The audio must be 8 channel, as that's how many speakers i have. Onboard or PCI is acceptable.
The video must be nVidia (ATI has poor support for Linux) and capable of running Compiz Fusion smoothly. This is vital for software/front-end plans I have for the future.
I require the use of 3 harddrives. 2x500gb sataII and 1x80gb sataII.
I will have all my accessories tied via USB hubs (3x4 port hubs for a total of 12 ports). Ports 1-8 will hold FM tuner, Bluetooth, GPS, Wifi b/g, Keyboard, Mouse, DVD/CD-RW, Lilliput Touch Screen. Ports 9-12 will be open ports to hook up external temporary devices (joysticks, stick drives, external hds, webcam, etc etc).
I will mainly be using this system as a MP3/Radio/CD replacement, but with GPS, Internet, Bluetooth capabilities. I spend a LOT of time in my car (with and without engine running) and while listening to my music I'd also like to be able to surf the web, or whatnot, with blazing fast speeds.
Sry for the double-post. I was posting from my phone and got a lil excited and pressed the wrong buttons lol!
This is probably going to be overkill for a vehicle, honestly. In a vehicle, you're not going to be able to hear the difference between 7.1, 5.1, 4.1 or anything else unless you're viewing/listening to something that is encoded for 5.1 or better surround. That usually means DVD movies.
I don't know what sort of video you require, but there are some quality motherboards with onboard nVidia graphics that would do you well, I think.
Using onboard video will save you some power, as well.
That's excessive, IMHO.I require the use of 3 harddrives. 2x500gb sataII and 1x80gb sataII.
For power concerns, I would go with a single terabyte HDD instead of the pair of 500GB units.
That said, the multiple hard drive setup is doable, but can be made more efficient. Just ask TheLandYacht, who has 2.2TB in his taxi!
Go with powered USB hubs if at all possible.I will have all my accessories tied via USB hubs (3x4 port hubs for a total of 12 ports). Ports 1-8 will hold FM tuner, Bluetooth, GPS, Wifi b/g, Keyboard, Mouse, DVD/CD-RW, Lilliput Touch Screen. Ports 9-12 will be open ports to hook up external temporary devices (joysticks, stick drives, external hds, webcam, etc etc).
Again, multiple USB hubs = more power draw. Consolidate the USB hubs and use less power.
Even with those specs listed, you will not need much more than 250W.
And, to top it off, use a Intel cpu with either mobile core 2 duo or desktop core 2 duo setup, they're at 45nm manufacturing process nowadays, and consume very low power levels.
So, you could most likely get away with a DSATX supply, and cut down to 1x 750gig to 1TB harddrive, you will be ok
Seriously, a terabyte of storage?! You can build whatever you want, that's what this hobby is all about, but I'd advise that if this is your first car pc, start smaller and simpler, then work your way up to the mega-install later.
music library of about 25,000 (that's twenty-five thousand, NOT 2 thousand five hundred) and it grows everyday. Movies are pretty large in size too (anywhere from 650mb to 4.7gb per movie) and I do have a lot of those too.
Thanks for all the feedback everyone! This is really helping me out a lot! Got my mind wrapped around a few things I didn't think of - we're off to a good start! Yay!
* I have attached my current mockup (mockup 3). Take a look to get a better idea of where I'm going with this. Maybe ya'll will see something that needs to be mentioned. Expect this to change a lot (like adding a 3rd amp on those 4 speakers, for instance)
(everything in the big grey box, I already own)
Looks great, but very complex. With that many USB devices and hubs, I'll be surprised if it all works smoothly and consistently.
One thing - I presume it is an extra battery you are installing. If so, make sure you have a tank circuit or battery isolator installed.
Between nearly 3,000 watts of equipment and charging the extra battery, you may need an alternator upgrade. Not sure.
