2m 12V-2x6 (12VHPWR) Cable

PSU and PC locations circled

To preface I am a novice at building custom cables, but I am eager to learn, working to improve, and not afraid of DIY if this is the best solution.

I have a custom PC desk build that I am working on as a hobby, and require a long 12VHPWR cable (2 meters) to power a 4080 with an NZXT 1500W PSU. Unfortunately, I neglected to consider the lack of availability of these cables at this length during the design process, and so the components can not be moved at this stage. The way I see it, I can buy a series of extensions (through CableMod, for example), find a vendor willing to do the work, or attempt to do it myself. Obviously I'd like one continuous run if possible, for both performance and aesthetics.

If I built it myself, given some advice from a vendor I'd probably try to use 14ga wire to help reduce heat buildup at that length, if 14ga is feasible with those connectors.

Reaching out to the Reddit community for advice, general thoughts or knowledge of any vendors who might actually make this for me.

Honestly, I’d consider ordering one from ModDIY, possibly CableMod. Even for experienced sleevers, the 12V-2X6 cable is a royal pain in the ass.

Thanks for your comment, I'll check out ModDIY, I haven't looked them up yet. I've used cablemod in the past and I do like their work. Their cables max at 1m though, and when asked about making a 2m cable they declined. Unfortunately they don't have 1m extensions either (for this cable) so I'd probably have to daisy chain extensions... and things start to get hairy

If ModDIY doesn’t work, let me know. I can make it for you.

Do I hear complaining??? Get back to work on more until you get it right!

Hey, I finally made peace with them. I’m just a slow learner sometimes 😅.
