The CORE of Your Next Upgrade

Corsair CJ

With this core builder bundle, you’ll have the necessary components needed to power up and cool a new graphics card in a case with massive airflow!


Our recommended configuration for the best balance between performance and aesthetics would be to install the SP120 RGB PRO fans in the front of the case and move the pre-installed AirGuide fan from the front panel to the top panel, positioned as close to the rear exhaust fan as possible.

Relocate fans with SP120 RGB PRO in front and stock fans on rear and top exhaust.

To ensure that you have your fans mounted the right way for airflow, make that the front of the fans are visible when looking at the front panel, the back of the fans should be visible when looking at the top panel and rear exhaust on the outside of your case!

Air intake goes through the front of a fan and exhausts out the back.

To configure your SP120 RGB PRO fans, check out this video where we show you how to use the kit’s Lighting Node CORE.

And you may also want to check this out for how to re-orient your fans in iCUE for animated lighting effects.

For your power supply, route the 8-pin EPS12V cable along the back of your case so it can connect directly to the power connector on your motherboard. It’s best to do this before you install anything like a fan/cooler in the top of your case so you have the most room to work with.

Built 4000D with power locations marked

Your 24-pin power cable should be routed from the PSU shroud up the cable management bar to meet your motherboard’s 24-pin connector.

If your graphics card requires extra power, route the cable up the PSU shroud through the central cable cover on your case, we recommend running a dedicated cable per power connector on your graphics card for best performance!

Built 4000D with general IO locations marked

Don’t forget to plug in the front IO of your case onto your motherboard. Generally the pins for the power button, reset button and LED indicators can be found on the bottom right corner of your motherboard. Double check your motherboard manual for the exact location and pinout of the front IO header! The front IO cables can be routed through cutouts in your case to keep cables looking tidy.

The audio cable will generally connect to a header on the far left corner of your motherboard, again, check you motherboard manual to be sure! This cable can be routed through cutouts in your case.

The USB 3.0 cable should go directly to a header on your motherboard, these can often be found along the bottom edge or right edge of your motherboard. Pick a header that works best for your cable management.

The USB Type-C cable should connect to a header on the right edge of your motherboard. If your motherboard doesn’t have a USB Type-C header, consider getting an adapter so you can plug this cable into a USB 3.0 header.

You’ll also want to make sure that you connect your Lighting Node CORE into a USB 2.0 header on your motherboard, most motherboards will have at least 1-2 USB 2.0 headers, check your manual for exact locations. Remember that the Lighting Node CORE will only control the lighting of your fans, you’ll also want to make sure that you connect your fan DC/PWM cable to appropriate headers on your motherboard or a fan controller if you have one.

Finally, we’ve put together this general build guide for building a PC from start to finish!
