Well i have that power supply, and i used to run 4850 till it died on me, so i bought PNY 9800GTX OC which requires 2xPCI-EX. Well i didnt look at that part and just ordered it, and when i came home from work i remembered that it needs 2x Pci-Ex cords... i have Coolmax V-600 powersupply and it has 600w. can it run the PNY 9800GTX OC ?? if i use the adapter provided and the PCI-EX i already have???. i would really appreciate the help!
