I have a problem with my 9800Pro@XT, it has to do with the molex thing where you plug the power cable.
The problem is, the power connector in my video card is burning all molex terminals I plug into it. The last time, even the white plastic from the molex turned brown, and I burned my fingers when I tried to unplug it.
The molex thing always burn at the red cable end (positive I guess ), and the 3 times, it happened after having my pc running for more than 2 days straight, and underclocking my vidcard to 300/300 (maybe this have something to do )
I see there's some kind of pattern, as first, my PSU died only two weeks after buying it, it was an Omega 450Wts PSU, and i got a new one after I RMA'd it.
Then, the fan speed regulator from my Tt Giant 3 VGA cooler burned out, I changed it for a new switch which I soldered to the old panel that came with my cooler. I even posted a thread about this here:

Then, the splitter power cable that came with my card burned out too:

I connected my video card directly to the PSU, and it has burned out two more molex connectors since then. After it burns the connectors, I get the "power cable not connected to your Radeon 9800" message at boot.
I'm certain there's some kind of relation between all those events, maybe something isn't grounded right, after the second connector burned out, I disassambled my whole PC, down to the case, and rebuilt it again using a borrowed PSU, and then it burned a third connector!
Is there any explanation to this strange phenomenon? My electric conection is grounded, and i have all the necessary precautions to keep any voltage irregularities from reaching my PC.
Please, help me with this problem, I don't know what else to do! I must admit I have almost no electric engineering knowledge at all, I only know the basics, thank you all for your help, I appreciate it
