You dont need to use the molex adapters that came with the card. They are for power supplies that dont have the proper connectors. Your power supply has plenty of the appropriate connectors. Use a 6-pin pci-e and a 6+2 pin(for the 8-pin on the card). According to the specs you have 4 of each.
Thanks that's all I wanted to verify and yes all my specs are accurate.. I have alot of computer know how just wasn't to sure with this new card I rather be safe then sorry don't wanna fry $448
