Frequently Asked Questions

Does the TECWARE Flex RGB kit come with PSU cables?

No. It only includes cable covers: a 24-pin motherboard cover, an 8-pin/16-pin GPU cover, 12 cable braces, and male and female 5V 3-pin ARGB connectors. You fit it over your existing PSU cables.

Will it fit my 16-pin (12VHPWR / 12V-2x6) GPU cable?

The GPU cover supports standard 8-pin or 16-pin GPU power cables up to 14 mm thick. Measure your cable bundle before buying. Anything thicker than 14 mm won't fit.

Can I connect it to a 12V 4-pin RGB header?

No. The kit is built for 5V 3-pin ARGB headers. Connect it to a 5V 3-pin ARGB header on your motherboard or to a compatible ARGB controller.

Can I control each LED on its own?

No. Each cover has up to 81 LEDs, but they can't be controlled one at a time. Your lighting software runs one smooth effect, color or animation along the whole cable.

Will it sync with my ARGB fans?

Yes, as long as the fans and the cable covers are on the same 5V 3-pin ARGB system. Plug the kit into your motherboard header or controller and it follows the same effects through supported lighting software.
