I just purchased the following LED Kit to use in my Corsair 760T case. What should I purchase in addition with what's included to have these LEDs work inside my case using a 1300W G2 PSU?

The bundle I purchased comes with a wire tail on the barrel plug (red & black) as shown in the attached JPEG.

After connecting the barrel plug to the small white controller box, do I then connect the wire tail to female end of the molex (matching red & black lanes) of this weird cable that I wanted to buy ? And then I connect the second female end of the molex to the computer PSU?

How do I use my 1300W PSU to power the LEDs?

Would this process also require the use of a crimp tool?

Red is +5V, yellow is +12V, black are both grounds (the one on the red side is for the 5V, the one on the yellow side is for the 12V but I'm pretty sure you can use both of them).

Here's the exact pinout, just for reference :

So if your LED strip uses 12V, then cut its power cable, insert the ground wire into one of the ground pins (the two at the center) of the male molex connector (coming from your PSU), and insert the positive wire into the +12V pin of the molex connector. You can use whatever you want for insulation, assuming both wires are held together they should stay in place and provide enough electrical contact to power the LEDs.

The second product you mentioned - the weird two female connectors molex cable is useless to you as you can't even connect it to your PSU. You maybe wanted to buy this cable instead which has a connector that can connect to your PSU. In this case, cut the black and yellow wires and solder them to your LED controller's power cable, like this :

And no crimp too needed, it depends on your level of perfectionism. You can use my dirty solution that I proposed above which just requires you to insert the wires into a connector and secure all of that with some duct tape, you can do better by using an actual molex connector and soldering the wires to it as proposed in my second solution, or if you really want to you can buy a molex connector and crimp it to the power wires of your LED strip, but that's way too overkill for such a simple mod.

I did this same mod, routing RGB LED tape through the case.

enter image description here See the box lower right external to the case.

I had the choice of using the PSU power, or powering it with an external adapter.
I chose to run it via a External wall wart adapter, first a 500ma one , which was not enough total power when everything was on full, then a 800ma one which was sufficent power. This was a single reel.

enter image description here

You can see the box there on the back (left bottom), with the external adapter wire that is headed to it.

I am very happy that I chose using external power, because it shorted to the case 2 times, and had to be adjusted (works great now). And I can use it as general lighting when putting boards and disks and all in and out, because it is independant.

At the least make sure you have some sort of fuse or curcuit breaker in there. shorting to the case will be much easier and a way bigger disaster using the same +12 used in the rest of the machine, this stuff is not rope light with the full insulations.
It did not surprise me when it shorted out, although I am sure someone using much more care and with a different case could prevent that. Then the tape comes loose and pow.
Led tape - $8
Adapter for powering it - $16
