Question:

Which PCI-E 6 Pins Power Connector Should I use ? Help Please!!?

Hello. I have ATI Radeon 5870, Coolarmax Powersupply, 2 PCI express 6 pin power cablesWhile Unpacking I found out there are also two more PCI power cables each with 6 Pins. Should I plug the one of the Powersupply or the other that cameup with my graphics card box ? thanks for help.

Answer:

It is always best to use the the one on the power supply. It is more reliable because it connects directly to the card. The connectors bundled with the card are more for contingency on older power supplies that may have none or just one PCIe power connector. That connector tends to be less reliable because there is another connector on the line to the two 4-pin molex connectors.
they are exactly the same in terms of power. I would go with the one on the power supply, as it will reduce the amount of cable in the case(thus reduce heat, clutter, etc). the one that comes with the gfx card is just in case the power supply you bought does not have a 6 pin connector(like many of the older psus)
