Can I use a HD 6770 Pcie 2.0 in my mobo port pcie 16x?

Hello,
I think to know, that the difference is the velocity of the channels and the Watts but I' m not be sure it will work.

Does it work putting a new power supply with 6 or 8 pin for the new video card?

  1. What are your full system specs?(CPU,RAM,etc.)

    It depends on what the card's power requirements are.
  2. The mobo is Asrock AliveNF 6P-VSTA (1 port pcie 16x)
    Video HD4650
    Amd 5200+ procesor
    4G mem Corsair
    Windows 7 64
    Power supply 450 watts

    Thanks in advance
  3. All of the 6770's I've seen are 2.1 cards.Are you sure the 6770 your interested in is in fact a 2.1 card?

    Your mobo looks like it's a 1.0 slot but I can't be sure.I would suggest going with a 5770 or a 6770 that is a 2.0 card to avoid any complications.

    What is the make/model of your PSU? How many amps are on the +12/v rail(s)?
  4. I really like is to change my video card.

    And if only I change the power source would be nice to me.

    I would like to be sure if anyone has been able to use a PCIe 2.0. a 16x PCIe slot?
  5. I have another power supply Mustiff of 800w EPS12V 2.2 specs, it has 8-pin(4+4) and 6Pin in the other computer, actually I can buy another one.

    May be I can try with this one, but I wanna be sure It could not damage the mobo

    Regards
  6. I don't understand what your asking.

    all of the PCI 16x standards are inter-compatible, the speed of the link is determined by the weakest component. The PSU should be able to handle your card fine too.

    They mention " That is to say its power requirements are entirely satisfied by the PCI Express x16 slot."
