  • How can I power a P4 3.0G

    I want to make a carputer it's my first one. I bought a P4 3.0G CPU, Intel Mini Mother Board, 100GB Notebook harddrive, and a note book DVD-CD-Rw combo. All I need is power for it. What do I do???

    You need Power and a Shutdown controller.

    For power I recommend an inverter and a standard ATX PSU.

    An OPUS 150 most likely will not work. The cpu pulls nearly 100 watts. Combined that with a motherboard, dvdrw, hd, you are definatly pushing pushing the Opus. If you want anything more like gps, wireless lan, etc. you will exceed 150 watts, if the hd and dvdrw haven't already done that.

    For the Shutdown controller, I recommend the CarPC Pro or EZ Power Controller (www.thecarpcstore.com).

    You can purchase both the inverter and controller from that site, and they will be wired to work together so you don't have to do it yourself.

      Consider this constructive critizium from an a__hole... Why the hell do you need a 3.0GHz P4 in your car?????? That is just overkill.....

      Nothing you will or can do in a car will require that kind of processing power... I am currently on my second CarPC and all I do is play MP3's, do some GPS'ing and once in a Blue moon play a DVD... and I bet 99.99862% here will fit in the same bucket.....

      Scale back, use that for you house PC, use a VIA M10000 or M12000 for your CarPC...... it will make you life much easier.

      But as you seem to already be doing

      HAVE FUN with this... this is one of the greatest hobbies around other than that....

        The Opus 150W should work. Initially I built my box with a P4 3.0 I had sitting around from another project. At that time I was using a PW-200, and it seemed to work with the P4 3.0 just the same as the P4 2.0, which is now the permanent processor for my carputer.

        Since then I've switched over to an Opus 150W psu; I haven't tried the 3.0 with the Opus, but I doubt you'll have a problem. If you know your exact CPU model, you should be able to look up its power consumption here http://processorfinder.intel.com/scr...sp?ProcFam=483

        [Edit: Notebook hd appear to consume ~5W]

            I am currently running a p4 2.8 with an opus 150 & a desktop hard drive, no problems & pretty solid, but when I add dvd/gps & a few more usb components I plan on adding another slave power supply. it will not need to have a shut down/start up built in because it could be controlled by the opus 150

              Never enough power...

              Greetings All,

              I'm in the "one can never have enough power" camp. I want my CarPC as fast as possible, for booting, and more importantly multi-tasking. I want to run my MP3 player, DVD and GPS at the same time and be able to switch on the fly. I regularly go to events that I photograph, so I do all of the above plus burn a CD of the photos that I download. Can't do that will a 1Ghz machine...

              Just the way that I like to use my CarPC... can't wait to upgrade to a P4 3.4Ghz with 2GB of RAM. Oh yeah...

              Cheers and Happy Holidays...

                olisim, turbodirve,

                Don't go Opus with the setup you have mentioned. Those who advise you to won't pay for a new one when the Opus dies prematurely. You will be pulling more current that an Opus is rated for, and it won't last. Been there, done that, don't recommend it.

                  That much power might even strain a Keypower 250 watt ps... You're probably better off with inverters, as previously stated.

                    It's 1.287-1.4V core voltage. I'm not sure exactly P4 3.0 775LGA it is but all 3 have relatively the same voltage. So with this info what do I get? OPUS? or PW 200

                      Neither. Go Inverter + 300 (or more) watt ATX psu. It's cheaper too, especially if you already have an ATX psu lying around.

                      Why? Because Opus's are not rated for that size of a load, and I have read many posts of people unhappy with the PW200, as it is not really designed for vehicle usage.

                        Opus is working on releasing a 220W power supply. No ETA yet. However it has been drawn up but no production. If you can wait 2-3 months to see the progress then I would recommend it.

                          Yeah, but that is going to be expensive. I'm sure it will be at least $200, (educated guess based upon previous models). And the inverter+ATX PSU solution $120 or less with a power controller that does much more than what is in an Opus.

                            It's not the voltage you're looking for in the CPU specs, the Watts are key. If you're not sure of which CPU it is, pretend it's the one with the max watts..

                              ehh i used one of them wattage calculators where you put together your system with a series of dropdown boxes, i think it was on that site where you buy the carpc ez shutdown controller

                              i have the p4 itx board with a 2.8ghz, 3.5" drive, 8 usb devices, and a pci audigy card, and it added up to 170-180 watts peak

                              i bought the PW200 that plugs right into the itx board, and that claims to be 250watts peak

                              it claims it supports up to 3ghz

                              whats the problem again?
