How exactly do having 2 12V+ rails work? Obvoisly it means there are 2 rails, but do have the conenctors that work on 12 work on one rail and the other half work on the other? Or what?

+12V1@18A, +12V2@16A,

How good would that be? I also have a fan and some lights pluged in(lighs that came with the case, lots of them though) and I'm getting three more fans, I have 2 harddrives, and two CD rom drives. I hardly ever use the second harddrive and can unplug it, same with the second CD-rom drive. I'll prabally get a HD fan also, and two cold colthode lights, the two cold cathode lights prabally wont plug into the power supply though.

Right nwo I have a really crappy PSU, 30on the 5v and 18on the single 12, so its going to be a inprovment obvoisly, but I dont have everything pluged in right now, and I plan on getting the three extra fans and all off that.

Basically how decent is it? If I get it i'm going to be tretching my money out a bit.
 
Having two rails means you have two different 12vdc regulators providing power to your system. Typically, one rail will power your motherboard and video card, and the other handles the peripheral devices.

This accomplishes two things-- one, your motherboard's power will not be affected by sudden load changes caused by peripherals such as CDROMs spinning up to read. Second, using two smaller-amperage regulators is more efficient and creates less heat than using a more robust high-amperage regulator.
 
So then That's prety decent? Becuase If it is, then I'll prabally get it, its cheap and has pretty blue lights lol.
 
Looks like a great deal, i'd say go for it. In fact, I almost bought one myself, until I found this one on ebay.
