    Shuttle PC and Power supplies

    My new install is going to be an AMD 2500+ AMD based Shuttle PC installed in a Chevy Venture minivan. Space and weight are not a problem. The Shuttle has 512Mb ram, DVD Rom and wireless network card and TV/radio card. Cables run to a dash mounted USB hub with Lilliput 8" touch screen and a 10" flip down monitor. Lilliput and hub are seperately powered by a voltage stablized 12V source.

    Question: the normal choice of OPUS PSU might be underpowered for this system and so I propose using a 400W invertor and a battery backup uniterruptable power supply ($100 or so). The idea is that the UPS will smooth voltage changes and will save the car battery when the Shuttle goes into Hibernate when the car is not being used.

    Anyone have any thoughts on this?

    Thanks

    Steve

    A fellow Steve. Great! I don't think you will have any problems powering your setup with the Opus. I have everything you see in my sig running off my 150W Opus and no problems as of yet.

    i am running a Shuttle XPC sk41g with 1.7ghz amd, dvd rom, 512meg ram, irman, and a 60gig hd, all off a 150w power inverter and it works fine.
    the ups would work, but i wonder if there is a better or cheaper way. if you havent yet check out the old posts on hibernation and i bet you can get some ideas.

    I just put together a Shuttle "Limited Edition" 800fsb, 2.4 p4, 1 gig corsair400 ddr, 160 gig SATA, 802.11b (integrated in Shuttle). I purchased a 400 watt invertor much like Steve suggests, anticipating that the 150w Opus wouldn't handle the above. Any thoughts? Will the Opus fit in the Shuttle confines, or install it remotely and wire it in? Or, install with the invertor, and upgrade to the 230w Opus in September? I believe the Shuttle A/C power supply is 250w.

    Thanks Guys

    I managed to pick up a small APC UPS for $70 and a 400w invertor for $40 and so I think I'll try the invertor + UPS first of all before 'investing' in the OPUS - I like the idea that it is independent of the car battery when the car is switched off and will drain the UPS rather than the car battery.

    As for DavidL I don't think the OPUS will handle the P4 which I believe has a power consumption on it's own of approx 85W - which leaves little headroom for the hard drive etc - whilst it might work you will probably find it will running at it's limits - an ampmeter in series will tell you what it's pulling - multiply the Amps by 12 for Watts.
    The 230W version would be sufficient (but expensive).

    Steve, I have read several threads about the toubles with an Inverter powered UPS. I hope it works for you. Most folks do not have luck with that set up (at least that I know about)

    If it does work for you post the model numbers for others to benefit from.

    Thanks Truckin

    I'll give it a try and see how I get on - after all this is what it's all about - experimenting and trying different things to see what works (reliably).

    uh... guys... an ups doesnt directly power the computer until such point where power is no longer supplied to the ups. at that point it switches real fast over to backup.

    an ups wont filter your line. so dispell thoughts of that. besides, it'd lead to greater trouble with the damned beeping, and turning off your machine when you want to turn it off.

    what i'd reccommend is an athlon XP mobile, underclocked and undervolted if you think you're gonna have power issues. second, get the opus.. it's the best idea. i think an opus and a decent board without too many addons can do on an opus. i power my comp with a 180 watt, and it's by no means efficient. the opus should do good.

    but back to the inverter and UPS. line filters cost hundreds of dollars. why? cause they put out clean power. HOWEVER, computer power supplies can take unclean power and make it relatively clean. you still wont get a full sine curve off the inverter anyway. imagine how it works.. it gets converted from DC to AC. (car 2 ups) to DC (store in ups) to AC (inverter in ups converts to AC for travel to computer power supply) to DC (the power supply breaking it up.

    that's like 5 hops, as opposed to 3. (DC-AC-DC). and it still wont clean your power. current draw from a computer is faster than the battery's maximum recharge rate. it *couldnt* work the way you think it does.

    Walley, He already bought it....

    Yes the Opus is better and more expensive. But this may work for him.

    To quote the UPS manufacturer - the UPS includes AVC - automatic voltage conditioning which allows an input voltage to vary between 90vac and 136vac and it automatically switches between mains input and battery. The alarm can be silenced.

    I'll try it anyway and let you know what happens
