Crimping Tool for PCI Pins

Jay85 · 2 Jun 2019 at 11:15

Hi Guys!

Modding some cables and i accidently snapped one of the legs on one of the motherboard cable wires. I've managed to source some new pins to replace the snapped one, but whats the best tool to crimp them down with?

Thanks
Jay

For small numbers, a set of needle nose pliers. The correct tool is, or was, very expensive.

Ah i thought as much, i may have to get a thinner pair of needle nose pliers. The ones i have seem a little too big for the job.

The proper molex crimp/pliers are outrageous in price

You can get a cheap crimp tool for £15 and several price points above. I got one and found it completely unusable for small stuff like fan plugs. You may be luckier with bigger crimps like ATX pins but I wouldn't assume so, at that price.

There are very reasonable value ones for closer to £50 that will be great to work with for PC stuff. If you intend to do any more future cable work of invest in those.

I custom sleeved my psu wires a while back, and the one I used was an Iwiss crimping tool. Costed me 19 pounds and it does the job.

I have one similar to this and have made up loads of fan extension cables, molex extension cables and pci-e extension cables with it and it's been excellent. Only a couple of crimps were messed up and that was down to me not putting the crimps in the right place when I first started using it. It's a ratchet crimping tool so you can pur the crimp in the jaws and squeeze the handles so that it just holds the crimp and then slide the wire in and crimp it up fully.

You could always solder the wires to the pins , depending on your skills.
I modded an old dell 330 desktop with 2 100mm led fans in the front, replacing the single dell one. Had to remove the pins from the proprietary dell connector and solder the fan wires the pins. Fiddly as owt.

The correct tool can be had for £10 to £20, it’s just a ratcheting crimp plier. You can crappy ones for even less.

I own these, they were on Prime when I bought them : https://www.amazon.co.uk/gp/aw/d/B01A0SAQ3W/ref=ppx_yo_mob_b_inactive_ship_o0_img?ie=UTF8&psc=1
