I recently bought a new AMD Radeon 7750 graphics card.
But upon installing, it did not boot up. I found that it needed an external 6 pin PCI-E power cable.
But my PSU didn't have one. (not even the molex connector)

So, My Question is - " Can I add a PCI-E 6 pin Power Cable or (molex connector) to my PSU with help of a Computer Engineer ? "

Hi :) 

You CAN buy a MOLEX bridge cable....BUT what PSU have you got ?, because you NEED a decent make 500 watt for that card....

All the best Brett :)

If your power supply does not have a PCI-E power connector or even an available 4-pin molex connector, then it will need to be replaced.

On a side note, I find it odd that your system does not have extra 4-pin molex power cables. Normally, it would and a 4-pin molex to PCI-E adapter like this would work.

One other thing that is odd is that the 7750 does not use an additional power connector.

My graphics card is MSI R7750 Power Edition 1 GB GDDR5 (OC +100 MHz) and that's why it requires additional power cable.
