DC-DC and my setup...
As some of you already know I among MANY people am having problems powering up my mobo without the PG signal. Even if i just wire the +5V it still requires a delay to switch the mobo on. ANYWAY!!
I tested my 70W DC-DC with everything I have and it doesn't power it up, even after disconnecting the 3 fans I have and the GPS receiver. ( I manually did the PG delay by waiting 1 sec after turning the power on). It seems like I would need 2 DC-DC converters to get all my stuff to work... =(
It does power up the HD and the CD ROM OR the Mobo. But not all. Not even Mobo + HD.
Anyone got a setup VERY similar to mine and is able to get everything running off of 1 70W DC=DC??? I know cenwesi can but I don't remember your exact setup.
Anyone got suggestions?
forgot to include the hardware info..

some pretty phat stuff in there i think your problem is your going to big on the processor and all that i'm not to knowledgable on that end of things so i don't really know but i think it's just to big a load no matter how you set it up
Your going to need more than 70W to run that thing. Hell, the start up current is probably somewhere around 200W. I would suggest checking out http://www.arisecomputer.com and looking for a larger DC-DC. Somewhere around 150W should work. As for the power good signal, you can simulate it with a simple RC circuit. All you need is one resistor, and one capacitor. Search the web for it. If you can't find it, I can post the simple two component diagram...
