I am planning on purchasing XFX HD4870 card. It requires a minimum power supply of 450 Watts and 2 6-pin pcie connectors.
My Power Supply has a supply of 460 Watts. The problem is that my power supply does not have 2 6-pin pcie connectors but rather only 1.
I intended to use molex converter from 4 to 6 pin. However I do not know that whether using them may cause some damage in the future? Can someone please tell whether its safe to use these molex converters?
I heard that two 12V rails with lesser amps than a single rail might cause a problem. I do not know how to judge whether my psu will cause problems or no. Please help. Here is the link for my psu's specs:

That power supply won't cut it. You can't go based on what the manufacturer says for power requirements. The 4870 actually would need a decent quality 600w or higher with 26amps on the 12v rail and an 80+ certification.
