ELECTRONICS SAVVY PEOPLE- Is this a viable & complete method to reverse polarity of EVGA Powerlink?

[Kaiido]

Hello I am trying to reverse the polarity on a EVGA Powerlink so I can use this on a Gigabyte GPU (the power inputs are upsidown), and would like some advice from some electronics savvy people. 

 

There is a tutorial online but its quite brief - https://www.overclock.net/threads/evga-powerlink-polarity-modification.1623897/#post-28858685

 

Is this a working method, or is it too risky and/or incomplete:

 

1) Cut off J3 & J6 wiring (railing)
2) Clean off solder from right side and remove bottom piece (power rail).
3) Drill 1.45mm holes for new wiring (rails).
4) Use rotary tool to score a line across underside (to cut tracers in middle of original rail position?) and add green stuff? - what is the green stuff - presumably an insulator?
5) Make new wiring (rails) using 1.45mm copper wire - crossing (one above one beneath) - switching J3 & J6 paths to reverse polarity.
6) Re-solder bottom piece (power rail) back on.
7) Make room for GPU connector latches - to enable them to be placed upside down allowing the device to fit onto my GPU.
8) Reassemble
9) insert GPU connectors "upsidedown

 

A few pics from the tutorial so you get the idea:

Couldn't you just desolder all the connectors and flip them around and flip the capacitors as well?  Seems like they're going through a lot of effort to reverse only 1 set of connectors instead of both.

Just swapping the J6 & J3 paths seems simpler i think... if it works. - the powerlink wont fit onto my GPU because the power inputs from the device are upside down. 

 

I just was wondering if the method was complete? -  (because i pieced it together from the original rather cryptic tutorial). 

 

I have not got much experience doing stuff like this, so I need a step by step guide... I think I am going to give this method a go, so unless anyone says its incomplete/wrong all I need to know is what is green stuff is? - so i can buy some.

 

After I finish the mod I will put it in an old system for a week or so because I am scared that I will fry my GPU.

I guess the green stuff is liquid electrical tape?

 

I'll give this a go within the next 3 weeks and post an update. If anyone has any advice or words of caution I would be very grateful.

 

Hopefully I wont fry my GPU.

Before you tried to plugged it in to your gpu try to measure if the polarity of each pin is correct with a multimeter also as janky as it is i would probably go with thicker gauge wire

I can confirm that this method works.

 

It was pretty easy, so if anyone accidentally purchases a PowerLink without realising the PSU inputs of the intended graphics card are upside down. This is a confirmed working option... if you really care about cable clutter.  

 

I tested the PowerLink before and after modification with a multi-meter - all was as intended.

 

And, I ran GPU benchmarking software - results post-modification were identical to pre-modification.
