I have a P5QLPRO motherboard and just obtained a Gforce 8800 Gt graphics card. When I installed and turned the computer on I heard a loud whistling sound and removed it. After further research online it said it didn't have enough power and that was the reason for the sound. I found there is a 6 pin plug in to the card for power. What should the other end of the 6 pin male be or what is the specific cord that I need to buy? Thank you for helping.
