Can I deliver more power to the GPU with a 8 pin to 6 pin cable adapter?

I have a Sapphire HD7950 3GB BOOST, which has 6+6 pin power connectors. However, I have seen other HD7950s with 6+8 or 8+8 pin connectors, and my PSU (FSP Raider 550) has two 6+2 pin PCIE power cables. So I searched around and found this:

http://www.cwc-group.com/8pin6pin.html

If I use 2 of these to convert my 6+2 pin connectors to 6 pins and connect it to the 6+6 connectors on the GPU, will the GPU get more power than with the 2x regular 6 pins? It would be good for stability and optimizing overclock.

It doesn't work like that. If it did, it would probably melt the ports from excess power from what is allowed.
But if you read the adapter specs, it states 225/300w to 150w. Which is good, you do not want 200w+ going into 6pin ports. You'd probably kill the card as well, as the manufacturer would have added an 8 pin, but made the card around the 6 pins. So it probably wouldn't support the extra power-and also overheat, if not fry immediately. 300w is plenty for a 250w tdp GPU. (1 6pin=150w)

Edit:
As you see here:

A PCIe provides 75w, and efficient 6pin should provide 200w, so theoretically 1 6pin is enough.
