If your PSU is modular, you can always use a multimeter to check resistance of the wires and any included connections.

The 24-pin and 8-pin on the HX-850 aren't modular.

If you're going to be splicing the wires, your best bet is using barrel crimps. Strip the wires, tin them with solder, push one in each end and crimp. Very easy, solid connection.

Barring that, if you're going to do it baskt_case's way, at least use heat shrink tubing, preferable with adhesive inside. I've seen many times wires that have been twisted together, especially stranded, come apart with a little bit of force. Electrical tape is not going to provide any sort of mechanical support to the joint, only insulation.

First try your RMA though.

Thanks for the help everyone. I will wait to see what RMA say about all this before attempting to slice the cables.
Will this work for long term use? My CPU pulls 200w.

Extensions (w/e the sort, brand, etc) always add resistance, and if the connection itself is poor/loose then you end up with melted cables & connectors (it usually happens on the 12v wires of the 20+4pin connectors, the CPU ATX/EPS melting is less common)... anyway, even if it doesn't melt your cables, it always impacts VReg (sometimes with severe effects). So extensions/adapters are not desirable independent of circumstances.
See how that RMA request goes, and if if fails, buy something that would reach the 8pin socket/s without extensions.

I'm trying to figure out if the extension saved my motherboard, or caused the whole thing in the first place.

This has also happened to me. Antec replaced my PSU, and I believe the cause for it was the quality of the extension, bought on the worse and most dishonest site in the business: performance-pcs. They treated me harshly when I contacted them and did nothing but insulting me.

Once it starts to melt, the plastic kinda acts like a conductor between the pins, and that's why it melts. So, stop using it immediately - for me the situation grew out of proportion because I took a LONG time to relate the extension to my problem - on the outside it looked normal for weeks until it started all melting and I could finally notice it. Plus it was on the back part of my case, which has only cable management and I rarely open.
edit: I was looking for a long while, because after intensive CPU activity, such as overclocking testing, I would a funny burning smell that I couldn't pin point where it was coming from - because it was in the back of my case

Today I'm still using an extension, but now a quality one and not as long, so it doesn't add as much resistance.

As to my motherboard it was acting oddly and I had to replace it. But I'm not sure it was related to the whole thing as being the cause.




Edit: now looking at the pictures you provided, I see that you were lucky to be using a white connector head that allowed you to see the melting quickly, as opposed to me.
However, looks like you are using the same kind of extension I was.

What was wrong with your motherboard?
