Power Connector Crisis

so I recently started building a computer and I had almost everything installed and I got to the case connectors for The Corsair 380T. I had plugged in the cables for the power switch, LEDs, hard drive LEDs, and the reset switch. I then got to some unlabeled four pin cables and I have no idea what to do with them. I watched a build log for this case on YouTube and there was no four pin connectors there was a Molex connector which I do not have. Also I do you not have nearly enough connectors for my fans. I have two fans on my water cooling radiator, and then one intake and one exhaust fan that comes with the case. The problem is I only have one 4 CPU cooler connector and one case fan connector. I also forgot to mention that I have to plug in the three pin connector (Though it only has one wire) for my CPU liquid cooler. I am really stuck here and I feel like there is something missing. Please respond ASAP

It sounds like those 4 pin cables are for the built-in fan controller on the front of the case. If it's anything like other cases with built-in fan controllers, you plug as many fans as needed into it, and then plug the molex connector from the fan controller to your power supply.

As for the problem with not enough connectors, you can get fan splitters in both 3 or 4 pin sizes, ranging anywhere from 1-to-2 splitter to an upwards of 1-to-4. The main thing to watch out for, if you're then connecting that splitter to your motherboard, is that the total fan amperage doesn't exceed 1 amp. Most motherboards have a 1 amp limit on any single 3/4 pin header that shouldn't be overloaded.

Also, assuming your all-in-one liquid cooler's 3 pin header does what I think it does, it shouldn't matter if it's plugged in or not. For example, the Corsair H100 has a 3 pin header that goes into the motherboard to monitor pump speed. It doesn't control or power anything, just for monitoring.
 
So pretty much i decided to read the insturctions (facepalm), and i realized that i was supposed to plug my radiator fan power cables into a y splitter and then plug it into the cooler. I realized that the ports were for the fans after watching a couple videos. I have successfully booted my pc to my bios screen. I only had 2 problems. 1-i only have a usb 3.0 power cable and i have an empty 2.0/1.1 slot and im not sure if i need a cable. I also am short 1 SATA power connector for my hard drive and will only be using my SSD for now.
 
Here's a cheap Sata 3 cable that should do the job http://www.newegg.com/Product/Product.aspx?Item=N82E16812422651. They have the same cable in like a million colors if you feel like color matching. It doesn't have metal clips though, so if you want it super secure then grab something at the $1-2 price range. lols

Anyways, what do you mean that you have an empty 2.0/1.1 slot? Do you mean on the motherboard? That case only has USB 3 so you won't even have anything to plug into the USB 2 ports on your motherboard.
 
Not sure what you mean.

That Corsair 380T has two USB 3.0, which should be on a single USB 3.0 cable that plugs into your motherboards USB 3.0 header. If you have empty USB headers on your motherboard it doesn't matter.
