Good crimp or nah?

(Not sure if this is the right section to be positing this in? It's kinda PSU related. Sorry if this is the wrong place though.)

Did my first cable crimps nearly 2 years ago. 8 crimps took around 2 hours! This time I was much faster & this is how they all turned out (couple photos below of one of the cables but all 8 are of the same quality). Is this acceptable? Where or how could I improve?

I used to work in wiring and we used to press thousands of these molex mini fit jr every day.

Tbh your efforts aren't too bad and would likely hold no problem.

What you do have though is all the conductors in one side of the crimp which may be related to the low gauge of the wire. Perhaps your heavier gauge power cables are more evenly spread out. There is some damage to the insulation and it almost looks like it could have be drawn in, but in this case you seem to have gotten away with it. We used to have so many failures due to insulation being drawn in. It completely destroys the strength of the mechanical joint.

Anyway yours are so much better than my personal efforts. I don't have a crimper so just folded the crimp over with pliers and blobbed some solder through it. Still holding after 8 years though.

I've had a close look of the conductor's & they appear to be spread out evenly?

What exactly do you mean by the insulation being drawn in? Do you mean the end has been squished down towards the crimp?

When I was looking into getting the tools to make my own cables, I read somewhere about the MDPC CTX3 crimpers being really good but overpriced (at £55 I can agree) and was referred to an alternative set of crimpers which were basically the same set without the brand tax. They cost me £18 on amazon & I couldn't be happier with the results they give me. Seems like the imperfections come from my inexperience.

I would aim to have all of the strands emerging from the crimp both for strength and so you can see/confirm the entire gauge of wire was crimped. Otherwise looks very serviceable and I'd be happy using it in a PC!

I'll be sure to do that when crimping the other ends & 24 pin set, thanks for the feedback
