Is it possible?

i.e. If I have two 12V rails, is there some sort of method to combine them into one 12V rail? I figured I'd just solder then together and hope for the best. :p
 
In theory, I supposed you could... Whatever circuitry that's in the PSU might not like it, though. Also... Why would you want to do such a thing?
 
I'm going to be doing a power rail mod, similar to the one found here:

But my PSU has 2 12V Rails, SilverStone ST52F. If I don't combine them then I have to run 5 main rails instead of 4 through my case. Since my case is small, I'd like to save this space. Also I don't want to have to worry about dividing the current up between components on two rails as opposed to one.
 
For rails, no.
If you are talking about the power connectors, yes. Just splice.

Ahhhh. I think you have your terms mixed up. :) A rail is a separate supply of 12V current. You'll probably notice that some of your yellow wires have a stripe on them and some don't. What it means is that if you have, say, two devices that draw a lot of 12V current and you put them on two separate 12V rails, then one device couldn't potentially affect the available current of the other device.

It looks like what you're looking to do is more of a case mod rather than an actual electrical modification of the power supply. If it's for aesthetic purposes, don't go modding the internals of your PSU. That could get messy.
 
Sorry, I used rails in two seperate terms there. I actually DO want to combine the two rails inside the PSU (i.e., the striped and unstriped yellow cables) into one, so that I get full available current on one single rail, instead of split available current. I'm starting to get the impression it's a bad idea, so I'll probably just run two instead of one and not risk messing up the internals of the PSU.
