Any LOW power desktops with external wall wart power supply?
Looking for an extremely low power desktop but that
uses an external power supply. Maybe wall wart style Desktop could use a laptop CPU such as Pent M or something Such a beats exist? |

Most notebooks support external keyboard, external mouse, and external monitor. You can usually run them with the cover closed, in fact. -Dave |

This isn't really a "desktop" as such, but this thin client uses a 50W external wall wart. It has an NX1500 processor, which is pretty under-powered by modern standards. http://h18000.www1.hp.com/products/q...Specifications And you can convert a low powered desktop, to wall wart powered, by using one of these. The "picoPSU" is a DC-DC converter, suitable from taking wall-wart 12VDC, and making the rest of the voltages needed by a motherboard. A power device like this should have some moving air over it - while conversion can be 95% efficient, the thing has next to no surface area for cooling. There should always be at least one fan present, to keep the disk drive cool, and the moving air can help cool this too: 3.3V@6A, 5V@6A, 12V@7A, , (input 12VDC, regulated) http://www.mini-itx.com/news/images/story0417-01L.jpg http://www.mini-itx.com/store/default.asp?c=10 http://resources.mini-box.com/online...anual-engl.pdf Something like this might make a good motherboard. http://www.newegg.com/Product/Produc...82E16813131007 You can fit a Core Duo at 31W into it. http://processorfinder.intel.com/scr...asp?CHRID=1042 The cheapest Core Duo is this one for $244. The necessary heatsink and fan come with the motherboard purchase. "Intel Core Duo T2300 Yonah 1.667GHz/FSB667MHz $243.99" http://www.newegg.com/Product/Produc...82E16819111180 Too bad there is no way to work out what total power is needed. For a system like that, you could use a laptop hard drive and a laptop CD to reduce power. The motherboard chipset is a mobile chipset, so just like a laptop, it tries to do the best it can to save power. The board has built-in graphics, and that means you don't need a video card. (No, this won't be a gaming box, unless you put a bigger power supply in it for the video card.) Low power systems are a pain to build, because you don't have any power to spare. Ideally, you buy motherboard and components first, and test them with a standard ATX power supply. Then measure the current flowing from the ATX supply to the motherboard. Once you have all the measurements done, under load, then you'll know whether one of those "picoATX" supplies would work. You can then shop for a power source known to provide the amount of power you just measured. If the wall wart is being called on to deliver a lot of power, make sure it is located where it has good airflow. If dropped straignt onto carpeting, half the surface area of the wall wart is insulated. Paul |

Just out of curiousity, why the requirement that the PS be an external
type?? wrote in message ... (Paul) wrote: This isn't really a "desktop" as such, but this thin client This is what I want but in this unit the power supply is built in If it had an external wall wart type power supply this would be perfect http://tinyurl.com/syls8 |
