I may as well jump on the bandwagon.. I have a friend that bought my old gigabit board without the power supply and was pointed to the standard few sites to to build one.. but so far he has blown 2 24 volt wallwarts.. They seem to work for a few minutes and then not..
My guess is the board is somehow feeding voltage back into the wallwart and frying it.. Could one use a power module from a b&w to power the 24/28 volt circuitry?? Any ideas why or how the external wallwart would be killed?? -----Original Message----- From: Joshua Coombs [mailto:[EMAIL PROTECTED] Sent: Thursday, January 12, 2006 7:40 PM To: G-List Subject: Re: [G] Another 28V question ----- Original Message ----- From: <[EMAIL PROTECTED]> To: "G-List" <[email protected]> Sent: Thursday, January 12, 2006 19:26 Subject: [G] Another 28V question > Is the 28V only required to initiate bootup?

Assuming you're not using ADC or firewire, there are no other additional draws on that circuit. Joshua Coombs -- G-List is sponsored by <http://lowendmac.com/> and...
