Thanks Drew and Jeff on the info on adapting a Dell PS. I might have one sitting around but I have to check voltage on it too. So Jeff, it is my understanding that the odds of my power problem is not likely due to mobo related cause. (But since that is the lowest odds, my luck is that is the prob. :) > A more likely source for shorts would be in the filter capacitors scattered > across the board, but finding any such problem would be difficult.
It's something like this that I'm worried about after the machine received the arc. We're talking smoke and small light show. But could be the PS too. > I would say that the weak link is likely to be your card, but you said it > worked properly on other machines. I never tried the Firewire card on other machines but the usb card is brand new and it clearly isn't sending enough power to the unit. The enclosure works fine on other machines. Firewire appears to not send ANY bus power to the unit as it won't even light up the led no matter which outlet I use. Interestingly, this includes hooking it up to an external powered cd firewire enclosure. When using the usb bus powered, it is barely providing enough juice to light the drive, hardly enough to allow copying, which usually causes a stall. Jeff, all the slots being on the same power bus is good info. > It is possible that you either have a weak power supply (stock Umax supply is > 250 watts, which is largish) or that there is a component on your motherboard > causing a weak short which is draining some portion of the available power, or > some other problem we have not thought of. For example, are you sure that the > root problem is a lack of power to the peripheral? Before doing a swap of machines, which I didn't get to yesterday, I will check the voltage on this PS. Will, thanks for the added info. I needed to make sure which wires were which and that it was ok to test while machine is running normally. Is there a need for using a digital over standard meter when checking? I have both but as you know, depending on application sometimes one is needed over the other. > The two black should both be ground and the red and yellow...I think one is 12 > volt and the other 5 volt. Jeff or some one will know for sure. Confirmation from someone on this would be helpful. Thanks, Dave -- SuperMacs is sponsored by <http://lowendmac.com/> and...
