Question Are there any 3-pin RGB extension cables out there?

[mrdata]

It seems the only one on the market, https://www.amazon.com/XSPC-3-Pin-Extension-Cable-Black/dp/B07D51XT4V, has been discontinued. Would a 4-pin extension work if I cut the missing pin? It's just pass-through wiring, correct?

Extending a 3-pin addressable RGB cable

Hey fellas, I've run into a weird problem during the final stages of my new build. First of all, I've got an addressable RGB strip, which uses a 3-pin connector (illustrated here). The problem is that the cable provided with the kit is only 5cm, which is too short for where I need my strip to...

I saw that post, but it didn't make sense. How would one jury rig a fan connector to fit? It's not clear how that was done. It would seem that a 4-pin would line up just fine if I cut off the missing, third pin as long as the wires are straight-through, with no crossovers.

According to this, the 4 pin extension SHOULD work.

OP, you are exactly right. Extension cables like this (and RGB Splitters) are just straight-through wires. As shown in the link you gave, the items often have female (with holes) connectors on both ends, and come with gender-changing adapters to convert the output end to a male connector. To adapt to the ADDR RGB (3-pin 5 VDC system) you need to do two things.

1. CHECK the cable connector for a mark indicating the edge for the +12 VDC supply pin on the mobo header. Check also the header for a similar mark. Make sure to match those up when making the connection.
2. As you say, snip off one of the pins of the adapter you use. BEFORE doing that, insert the adapter into the output end of the cable. Then make SURE you locate the +12 VDC edge of the connector and snip off the correct pin to duplicate do the arrangement of the mobo 3-pin ADDR RGB header. Then when you do plug in your lighting device's 3-pin female connector it will be connected properly.
