Hd 7750 and Pci-e 3.0 150W

This card is designed to use less than 150 watts. IF I remember correctly, the revision of the 2.1 brought about the pci-e card slot's power supply, to be increased to 150W from 75W, from the slot alone. Will this affect 3.0 the same way? IF so, why do these cards come with a pin connection if they are under the slots max power supply (far under)?

  1. the 7750 does not require aux power through a 6pin connection. you must've been looking at the 7770
  2. std clocked 7750 do not come with power connection but OC cards do. Most likely it is because most people are using motherboards with version 2.0 slots which are still limited to 75 watts! It is called backwards compatibility.

    SO, AMD is making the 7770 backwards compatible by adding the 6-pin pci-e slot. Then, would it be safe to assume that the 7770 can run w/o 6-pin, in a 3.0 Slot?

    If everything on it is wired for that it could because it does not require 150watts.
  5. Guess it is time to check on amd sites for the answer.
