No matter the rail configuration, every component will draw no more or less power than is needed. There is no less chance to shock your parts on a multi-rail. The idea of multiple rails was so no one connector can draw more than 18A. This is a good idea in theory but in the real world it doesn't really make much difference. If a component shorts out it will not be able to draw more than 18A, which is better than say 60A (the whole 12V capacity for the Corsair 750). But it is still shorting and killing the component, although with less of a chance for complete disaster like a fire since there is less current available. But in the real world, this hardly ever happens and isn't something that you should really be worried about. The number of rails should be the least of your worries. If I didn't explain it well enough, let jonnyGURU answer it at length: http://www.overclock.net/power-suppl...ml#post3614982

I still think that no matter what, you're going to have to do some cable management so what's the point of paying extra for a modular
The pic I posted above is of a OCZ 600W GameXstream with (2)Molex->6pin adapters.... that's an insane amount of cables and I managed to route them just fine
While that is a fairly good PSU, I think we could do better for the price.
Now to the OP, If you decide to get 2 4850, I think the Corsair hx620 or the tx650 would be a good choice but if you plan on getting 2 4870s you should probably get the tx750
, the PC P&C Silencer 750
(this is a bit long at ~7" so you might want to avoid that one since it is only an inch shorter, unless that is enough to make a difference) or the Hiper Type-M 780W
(same internals as the Corsair, but it is also ~7" long) since they draw ~160W each at stock. If you wanted modular get something like the Xigmatek 750
(same internals as the Corsair and Hiper) or the DA750
(also a little on the long side at ~7" compared to the Corsairs and Xigmatek at 6.3").
