multiple power supplies?

Can anyone tell me how well they might work? I'm starting to plan a mod, and it's looking like space constraints are going to stop me from being able to use a standard ATX PSU. So i was thinking about using 2 500W server PSUs, or about 6 or 7 200W mini-itx PSUs. Both of which would have to be rewired so support PCI-e connections and such. Would everything work fine just as long as enough power can be delivered to each copmonent, they are all linked together to power on at the same time, and there is a consistent ground connection between all of them? Also, does anyone know if a Pci-e video card pulls power from the PCI-e bus and the 2 power jacks or is it just the 2 power jacks and then negliable power from the bus?

Yes, people sometimes chain PSU's for larger builds. In some cases a multi-rail PSU is nearly the equivalent of several smaller PSU's ganged together anyway. Your biggest issue would be ensuring that you're getting enough amps from a smaller PSU if it is not designed to do so. Otherwise your plan seems sound.
A bus station is where a bus stops. A train station is where a train stops. On my desk, I have a work station…

Yeah, I'm planning on pinging it out and testing the amperage on each line with a normal PSU before I switch things over to the smaller ones. I'm also trying to use mostly ASUS parts in the build, I really wish they made a water cooled 570, or 580 like another company that will not be named. So more likely then not, it'll be an ASUS/DangerDen build aside from a few pieces they don't make.

I'd probalby use one of those if I wasn't completely rewiring the power supplies, plus anything I can do to reduce space cost I am. I'm basically trying to take the craziest set up I can think of/afford and shove it in the smallest space I can ^_^
