Run 5770 CF on 550w PSU?

Hello, I was wondering if I could run two 5770's in crossfire with a bfg 550w power supply. I only use one hard drive, and one cd/dvd writer/player drive. I also use a amd athlon x4 635 witch doesnt take that much power up. Thanks.

More about 5770 550w
  1. ASAP
  2. Which BFG 550W do you have? I would think it would be alright. The 5770 doesn't take all that much juice. I believe the crossfire requirements are 600w but if its a solid unit you will be alright. That is total system wattage to.
  3. link wont work

    Also, would this be better than a cooler master eXtreme 600w psu? it is only 5 dollars more, but 70% efficiency and the quality isnt as good i dont think.
  5. I would vote for the BFG. They both have 2 18A rails however the BFG is more efficient at >80%, the CoolerMaster is >70%
  6. Alright. And you think my system would be okay with that? I don't have an i7 or a bunch of drives, so I think I should be alright...

    If you haven't bought either of these power supplies yet they are not the optimal choice. Either would probably be alright but for an essential component like the power supply you should go for a respected brand like Corsair or Antec if at all possible.
  8. ^ That is very true. I was just really answering the ops question.

    If you are buying from newegg, this would be a better option. Has a $10 promo code making it $50. My buddy bought a few of these for builds, and they are great.

  9. Hmm... thanks much for the advice. I am looking to play games such as mw2, cod4, battlefeild bad company 2 (idc if its the highest settings - just averagely high). With one 5770, should I be fine with my current setup (athlon x4 635, 4gb g.skill 1600mhz, 5770, cf ready mobo)? I was thinking to get another 5770 soon but I thought about it and I would rather spend my money elsewhere. Should I go with a good quality PSU that is about 450-500w then? (my budget for a psu is abour 40-60$).

    and I might get a corsair h50 for my cpu
  10. the 500w antec jay2tall linked actually has one more amp on its 12v then the BFG 550w. the BFG is a topower unit, nothing special but still better then the CM.

    i would say for $50 you wont beat the antec linked above
  12. what about the antec basiq 500w for 50$? Same price overall as the earthwats one.

    edit: nevermind, reveiws werent to great and my cm storm scout wouldnt look good with the white color
  13. The Earthwatts is better. It's a good deal and a good choice.
