Any suggestions or even quick links would be appreciated.

Both supplys will be independant. Pin 14 is the signal line used to turn on the power supply itself.

are you certain that this will not cause damage to whats looking like a 2thousand dollar project.

If theres a safer expensive way ill go for that

perhaps you can hardwire the second psu to a switch and the other to the motherboard as you normally would. im imagining that you will be powering something like a large hard drive array or the like with second psu. so you could basically switch on the second psu and hit the on button and be good to go. although, if its for something like powering your sli/crossfire setup with the second psu, i would be worried that this method could damage the cards. and honestly, im pretty sure that method mentioned above will work perfectly fine. if you want to test it out, wire it up and plug in a psu testor and see if they either blow up or turn on. worst case scenario you get a mini fireworks show and 2 dead psus.

Don't take it the wrong way, but if it's that expensive a project wouldn't you be better doing a little bit of reasearch yourself, then posting a "Will this work" kind of thread, instead of asking people for a solution then questioning it when you get it?

"the biggest, baddest power supply, period!"

Ha haa

now i see why


EDIT: dude i gave you the pics, that thing is fine, if it blowes in youre face you aint doing it right, and if you got that much money i say you should go with the "the biggest, baddest power supply, period!"

If you wanna get a lil more technical about it, and isolate the PSU's more completely, you could go for a relay setup - I got one workin a couple years ago when I wanted 2 PSU's for one system. The only minor problem you MIGHT come across is that some PSU's won't fire up without SOME drain on them - so you MIGHT have to create one to get the second PSU to work properly.....

You'd use one of the molex's on the Primary PSU to activate the relay connect the green and black wires on the second PSU...
