Will these rads support cooling my system?

Hey guys.

Soooo I'm finally trying to get around to watercooling my rig. All I really want to cool is the CPU as well as my dual 780Ti Classy cards. I am planning on buying a kit from EK for the CPU stuff, I know my case supports a top 360mm rad so I am getting the L360 kit, which comes with an EK Coolstream PE 360. I am also planning on adding an additional 240mm rad in the front of my Corsair 750D, which is pretty much the only other spot where I can fit a supported double fan rad. I have a couple of options within my budget of 600-ish dollars, namely an Alphacool Nexxos XT45 or an XSPC EX240. My question is, will this be enough cooling for the hardware I'm connecting to it, or will I need more?

Additional question: Am I being an idiot, buying a kit? I haven't been able to compile a list of parts that can compare in price, really, so any help would be great if you know of a way to un-stupify my idea.

Thanks guys.

It is enough cooling capacity, buying one of those kits and adding to it is not a bad way to go. Just make sure you don't get a radiator with aluminium fins or tanks, because the one in the L360 kit is copper. The ones you suggested are copper as well so either of them will be fine. There should be enough tubing in the kit as well so i would not worry about that. The only other thing would be to just buy the same size fittings that are in the kit to use withe the other stuff.

Yeah, luckily Performance PCs where I am shopping has options to add fittings so I just went with the same size fittings in the kit for the GPU blocks and the extra rad. At this point I'm just trying to figure out if there's any small savings I can get on the whole system that won't end up crapping out the quality of the loop.

I cant think of anything that would cut down the price by much. From memory the kit you are going with is priced rather well. With that said I'm not really up to date on the prices of water cooling gear so maybe someone else will think of something that i overlooked.

Well, I just put together a different shopping cart with some recommended parts from a low budget watercooling guide in addition the the extra stuff I need, and it's actually about ten to twenty dollars more... Really the only thing I could change is some of the fittings, but my vanity demands compression fittings instead of barbs where they will be visible. Which, considering I have a giant case window, is basically everywhere.
