[SOLVED] 6-pin GPU cable question

Okay so, while cleaning the PC I noticed that the 6-pin cable had a loose wire and was ripped from its pin during disassembly (the pin head is still inside the header).
The pin is the 6th pin from the "PK8" cable mentioned in the attached diagram, it is mentioned that its a COM pin which I assume means that the ground is common between all pins.
Can the power supply still power the GPU "R9 270x , requires two 6-pins" or will plugging the cable damage it?


PSU: Thermaltake Smart 530w 80 plus (Yes I know its not good but it is all what I have to power my PC)

Thanks in advance.

You should not run with a missing ground, that means all the current is flowing through one wire.

Option 1) New PSU

Option 2)

You should be able to extract the pin from the connector.

A pin (sewing) or a precision screwdriver should be small enough to depress the two tabs that hold the pin in (you insert from the side you plug into the connector)

Once extracted, unbend the crimps intended to hold the wire, re-insert the wire, and smash it back down, and then re-insert the pin/wire.

Option 2b)

If the connection was originally soldered and the wire itself has broken, then you should consider ordering some new pins and a cheap soldering station. If that is beyond your means, consider option 1 again.

I tried option 2, but I think I did not connect it properly as there is this symptom:

PC works fine, boots into windows and everything is working fine. However, the moment I open ANY 3D application/game, within 1-2 min the PC black screens and hangs.
Does this sound like PSU is not able to handle the load due to poor wiring and the GPU turning off?

Yes.

The PSU may be failing coincidentally, of course, since it's a pretty junky one. I don't think I'd continue running a good PSU missing a ground, but I'd absolutely stop running a horrible one.

Okay one last question, if I were to take the ground cable from the 2 pins that are used as an extension (6+2 pin) and directly replace the entire ripped pin in both 6 pin cables, would that work?
