    How many people have a pair of Opterons though? I thought we were
    talking consumer PCs?

    log on to siliconchip type in pc power supplies
    into the article search box, it will take you to the new
    article,s but not the old one for the dummy loads.
    i asked them for it but thay wont to charge me.
    i will see if ican fined it in my folders.

    thats what i read from silicon chip and have
    done so and it works fine.
    im useing a 200w one to power a 16/ch mixer
    i have built in the last 2 years.
    im useing a nother one power my modem
    and network hub and some fans.

    This appears to be Intel's ATX specifications. It is not clear what
    minimum load is required for proper regulation. Under "DC Voltage
    Regulation", it says:

    "The DC output voltages shall remain within the regulation ranges shown
    in Table 2 when measured at the load end of the output connectors under
    all line, load, and environmental conditions."

    Later on in: "No Load Operation", it says:

    "No damage or hazardous condition should occur with all the DC output
    connectors disconnected from the load. The power supply may latch into
    the shutdown state."

    Loading examples never go below 1 A on +12, 0.3 A on +5, 0.5 A on +3.3.

    So, it shouldn't blow up under very light or no load conditions, but the
    exact values needed for proper operation may not be obvious.

    And, the existence of this specification document doesn't necessarily
    imply that all Far East ATX power supplies are fully compliant.

    Don't believe 'more than one website'.
    Look at the specs for your drives.
    The makers website will list exact startup currents.

    i think you need some load to make it regulate properly

    i found the artile, its from december 1998
    silicon chip.
    on front page is has make use of that old pc
    power supply.
    min load 47ohm 1 watt resistor, ive tested it up to 100ohm
    and is ok.
     
  9. So what? Does it say the specification allows for that high a resistor
    or just that someone did a project and it worked, and you did a project
    and it worked? The article doesn't appear to be archived, so are you
    going to share what it says?

    i sed i tested it up to 100ohm.
    if you dont beleave me, just bloody try it.

    look i have done it and it works.
    the fuckin aticle is in my hand.

    if dont beleave me then, its youre bloody

    if i had youre real email address
    i can send these pages to you
    but i havent.
     
  12. And you've tried it on how many different manufacturer's power supplies? :)

    You can contact me via the link below.

    laws.
     
  17. crazy frog

    crazy frog Guest

    the silicon chip aricles are copyright
    i cannot send it.
    but just take my word for it.
    47ohm to 100ohm.
    or you will have to log on to them and
    ask them.
    sorry about that.
