PSU mods: reusing ATX pins?

post #1 of 6
Thread Starter 
I'm currently in the process of building a SFF system based on a Lian Li PC-V354B, and I'm in the middle of modding my power supply to make the cables the correct length as to not have to mess around with cable management in the small chassis.

I'm looking to re-work all of the cables on my Xigmatek power supply so that they are much shorter than stock; the good way of doing this is obviously butting and re-pinning the cables to the appropriate length. For SATA connectors and such, everything is ok, but for the ATX 24 and 4 pins connectors, I'm confronted with a problem.

Can the ATX pins that fit inside these connectors be re-used and recrimped without having to purchase additional pins and the molex crimping tool? At under 10$ for an entire PSU's worth, I wouldn't really mind buying new pins, but buying the 20$ crimp tool for a one time job seems kind of pointless.

Please don't suggest cutting and soldering wires individually between the PSU and connector... I want to do this the right way, I just want to know if the crimp tool and news pins are ABSOLUTELY needed to get the job done correctly.

You should use new pins, but it's possible to crimp with normal needle-nosed pliers just fine. The tool is good for making the crimp robust and strong. It grips the housing as well, so that the wire won't easily be pulled out.

Sorry, but i'm like that. I did and would (if i still have to do it again) cut the wires and resolder them, it's not that hard and i bet you can do it wink.gif
If not, you'll have to replace the pins frown.gif unless you want to spend a huge amount of time recovering the old ones rolleyes.gif

good luck

Yeah, I guess I'll just do it right the first time and order a batch of spare pins. Trouble-shooting loose connections and intermittent problems on a 24-pin connector isn't something that I want to do a month from now...

Besides, I don't have the $$ for the whole rig now due to an impulse purchase, so I'll just wait out for some of the parts and do the PSU correctly in the meanwhile.

Thanks for the input.

to do it "right", either get the crimping tool (i gaurentee that you will jack up a few wires wile practicing with needle nose pliers) or resoulder the cables (better option IMO as it is cheap)... i would also get some paracord and heat shrink wile your at it to make you rig look nice (it is extremely cheap smile.gif)
