  • sproggy powersupply

    Just a quick question... uhm well...

    Can anybody tell me if sproggies PSU wil have enough power to run a MB + athlon tb 850 + gforce 2mx tvout + philips accoustic edge + 40Gb maxtor?

    And if not, does anybody know how to make/ where to get a powersupply that will do the job?

    Cheers!

    no, you will need a 250watt supply

    KP-DX 200Q (12V DC -&gt; 200watt AT) $121
    KP-DX 250H (12V DC -&gt; 250watt ATX) $164

      thanx for your comment bgoodman, but $165 doesn't fit in my budget, could you tell what can be powered with sproggies PSU (cahnging only the MB & proc)?

          I built sproggy's power supply. The problem you will have with it powering that much stuff because it has trouble supplying enough 12V current. I'm working on a modification to help this out using the MAX1771. I also made a bit of a mod to up the 5V current. Basically ran two MAX787's in parallel... I'll have pictures posted soon.

            Maybe I also could do something like that
            Using 2 MAX787 and 2 MAX788 will supply more than enough power vor the 5v and 3.3v

            Have to search for something that can handle like [email protected] (and then maybe use 2 of them ??)

            Q:
            Do computers use more than 5a @ 3.3v
            (I'm guess it's only needed for memory and processor, but do they use so much power?)
            (I ask this because I have 2*MAX788 and 4*MAX787 and when the computers don't use too much current at 3.3v, than I maybe could use the other parts for a second power-supply, cause I don't think I will only build one... girlfriend already likes the Idea and also wants one )

              I'm wondering....

              after looking hard at sproggies schematic, it seems pretty easy to get +5V @ 10A , +3.3V@ 10A,
              only problem is the 12V part, I cant figure out why the max. current is so low, I checked national's website and it says that the max current is 5A, so is the T6 the problem? I don't get it...

              Cheers!

                The power supply I'm building will supply 2 amps at 12 volts. (that is with an 8-14 volt input.)

                If you want to make sure that your input won't go below 11 volts, it will supply 3 amps.

                If you make sure it won't go below 12 volts, it will supply 3.3 amps.

                I just tested it for 5 minutes drawing 3.5 amps with a 12 volt input and it worked just fine.
