Help with Switching Connectors

post #1 of 6
Thread Starter 
Hello everyone,

Foolishly, I bought some bitfenix extension cables with the understanding that I could just plug them straight into my motherboard/gpu and psu however as they're extensions I obviously cant directly plug them into my PSU as i thought i could.

So I was wondering, would it be possible to simply switch out the PSU side connectors on the sleeved extensions with those from my actual PSU chords to allow me to use the sleeved extensions by themselves?

I don't see any problem doing this with the 8-pin PCIe and EPS cables however with my 20+4pin cable, the 20th pin wire is missing as I've read is the optional 5v line, while the sleeved extension has this wire, and the other problem is that one of the pins on my PSU connector has 2 wires running from 1 pin however the sleeved cable extenders only have 1 wire running along here.

So basically my question is, will the 20+4 pin run fine if I a) add the additional 20th pin 5v line and b) use only a single wire from the first pin rather than the 2 shown on my PSU chord?

Hopefully I've explained this well enough, if not, just say so and ill throw up some pictures of what I mean.

Thank you in advance for any help!

What power supply do you have?

You would not add the 20th pin unless you were 100% sure you knew what was on the PSU side. They can add it onto an extension to make it look better because the extension plugs into a socket that doesn't have this pin populated.

Depending on the PSU you may not need that extra wire on the dual wire connection.

You need to be careful replacing the connectors for the PSU end. If it's decent power supply then getting the 24 pin wrong probably would be OK as it will have short circuit protection built in which would stop the PSU starting and damaging the motherboard. If you get any of the other connections in the wrong place e.g. swapping 12V for Ground then it will destroy components including motherboards, hard disks and graphics cards.

A bit of time spent with a multimeter and possibly a PSU tester could save a lot of problems or damaged components.

It must be because I'm ill but I forgot the most obvious reason why you can't do it. The pins on one end of the extenders are male but those that go into the PSU are female, so no you can't do it.

I have a Corsair AX860i
This is what i mean, my intentions would be to replace the male extension connector with the female one that is part of the 20+4 pin chord that came with my PSU so that i could plug that directly into PSU

Sadly it won't work. The pins on the extension are male and won't fit the connectors.
