my "stock" dual PSU answer
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
a rudimentary tutorial for ATX dual PSUs
----------------------------------------------------------------------------------------------------------
synch 2 PSU each as a seperate bus
1. Hardwired (what a CMStacker's adapter does)
2. With a relay
or employing a shared bus Like a redundant PSU
1. with resistors
2. with mosfets
3. with diodes (Single Source Fault Tolerant Power Systems)
(3 is slightly outdated now see gee's post > http://hardforum.com/showthread.php?t=776885)
I ran 2 hardwired 400 watts and a large RAID array for 3 years without issue on one of my boards (Abit KR7A)
however it may have been a contributing factor in the death of another board (ECS whatever )
though Im not at all sure about that
not running them synchd however certainly corrupted the hell out of the array
eventually switched to a Zippy Emacs MR3-6450P N+1
with considerably less total wattage but plenty for what was actually required
with 32A on the +12V rail for the drives and considering the mobo's VRM was powered off the +5V

for hardwired thats
between the 2 PSUs its
green to green (POW_ON \ power on)
black to black (COM \ ground)
and on just the second PSU
grey to black (Power Good to COM\Ground)
or another commercial method
