    Hey all,

    I want to replace the MDD psu with an ATX psu. I want a cheap one to work, not really in the market for spending a ton of money.

    primary reason is to get the G4 to shut up. it seems like the PSU is the loudest thing. (wind tunnel)

    here are the two that i'm looking into:

    Rosewill 350-Watt Power Supply ATX12V RV350-2

    Solid Gear TFX12V 350-Watts Power Supply SDGR-TFX350

    are these sufficient to power the G4?

    the machine is a FW400 dual 1.25ghz

    please let me know, also would love to hear form any of you that done this...

    I plan on following the instructions on: http://atxg4.com/mdd.html
