    Depends on the brand. Tell us the name.
  2. either card will work with that PSU, although as hallowed_dragon said you need a good brand of PSU (not to run the cards, but to avoid PSU problems)

    also, get the 5770, it is so much better, you will be glad you did.
  3. I have got PSU of Zebronics model ZEB-450W SATA Plus (20 + 4 PIN)

    Please tell me whether it can handle 5770.
  4. A 5670 would be fine, but I'm wondering whether the 5770 would work properly even though your PSU meets the requirements.Post your other specs so that I can have a better idea.

    AC I/P - 115/230 V
    DC + 3 .3 N/ + 6
    D/P 25 A/24 A

    60/50 HZ
    -12 V/-5 USB
    0.8 A/ZA

    + 12 V
    16 A

    -5 V
    0.3 A
  6. I would say no...
  7. Though it should run the 5770, I would still recommend upgrading in order to have better stability.

    It only has 16amps on 12V rail and i'm pretty sure it doesn't have 6pin power connector, right?

    This Pro Series should be able to handle HD5770:

  11. It should handle it, but i'm not sure of Zebronics quality :??:

    what about the this PSU http://www.zebronics.net/pro_600.asp
    for MSI R 5770 hawk twin froz with 1 GB ram
  14. It's good psu. Can handle even tri-crossfire 5770.
  15. That would be an overkill for just 1 HD5770, but if you want to CF them then that's okay, go for that... :)
