Is a 400W PSU enough for XFX Radeon HD 5770 1GB GDDR5?

I'm just asking, the recommended PSU is 400W, but is it enough?
Thanks.

  1. A good quality branded 80+ certified PSU from the like s od Corsair/seasonic/Antec etc then yes.
    Some cheap grey box from the value range or that came with the case then most probably not.

  2. If yours is a dell, it'll be fine. Can you take a quality picture or read us the information from the power supply label?
  3. Which brand PSU is it?

    Not all 400W PSUs are the same. Example 1 = 276W +12V power (23A total) Example 2 = 360W +12V power (30A total)

  5. Sorry for the time it took for me to reply.

    System specs: Three drives, Intel Core Duo Q6600, nVidia 9600GT and four gb ram.
  6. Good to see it's a Fortron - while not a top tier it's usually a solid, reliable MFRG.
    With dual +12V combined wattage of 348W max or 29A.
    You're in very good shape to run a HD 5770 without any problems.


  7. What games are you looking to play, and what is your monitor resolution?

    The total peak power consumption won't be far off the 9600GT

  8. Fortron is one reliable brand dude:)

    Your PSU should easily handle that card. Go for it :)
  9. Thanks guys, I thought it was some cheap stock PSU. I'm playing BC2 atm with everything on low. I can play it without any lag and do good, but it would be nice with some eyecandy :D
  10. Edit: Native resolution is 1920x1080, but anything higher than 1440x(something) is fine. Is it possible for the card not to fit apart from lack of space? I can't edit my posts ._.
  11. The 5770 is not a long card so you should be OK there as well.

    BC2 @ 1920x1080 will push the 5770 hard. You might have to lighten up the graphics settings and image quality a notch but it should be a noticeable upgrade over the 9600GT.

    Nice, I didn't expect it to be that good. Anyway, thanks for the help :D
  13. I'm running a 5770 with a 400Watt PSU, It makes me slightly nervous but ive encountered no problems so far, though eventually I plan to upgrade the GPU.
  14. After reading reviews, watched some gameplay on Youtube and read your advices I've bought the card. It's good enough for my standards and fairly cheap. Thank you.
  15. I have a Sapphire 5770 and I am running two 23" monitors.This is a great card for the cost. I have a 750W PSU from Ultra4(Lifetime Warranty) and I see a little lag if I play video games,but not enough to make me lose. So stick with a high end PSU.
