H7874 power supply

Yeah, mine is full of "Nippon Chemi-Con" electrolytic too. What about just gutting the PS chassis and sticking in an ATX power supply? I don't know how the maximum current per output breaks down, but as I understand it the H7874 is only a 600W supply. That's not a problem for an ATX supply, and it would have all the required output voltages. You'd have to run the cabinet fans at a fixed speed and you'd lose the power control bus feature, but that's not a show stopper. Actually my unit is in an R400x chassis full of RF drives, so I believe I only need +12 and +5. I don't think the 3.3v and -12 are used in that case. I wonder how much current I really need for the drives? I should look that up and I might be able to find a surplus dual output supply that would do the job. Thanks again, Bob
