Is my PSU enough for a XFX 4890?

I have another noob question regarding the new graphics card that I just purchased, the XFX Radeon HD 4890. Now, the manufacture's site says the minimum required PSU is a 500W. I do indeed have a 500W PSU, but am not sure if that will suffice. Below is everything that hooks up to my power (500W Power Supply (20+4Pin)). Do I have enough power?

  1. What are the brand and model of your PSU?
  2. Well, my PSU came with my case that I bought:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16811156062

    I suppose that's another thing hooked up to the power as well, hah, all the fans on the case.
  3. Just checked inside the computer, it's a Raidmax RX-500s
  4. Best answer
    The pic of the case shows the PSU with 22 amps on the 12vlt rail.


    Hmm, a better quality PSU would be reccomended.
  5. Here is the PSU on Newegg: http://www.newegg.com/Product/Product.aspx?Item=N82E16817152029

    What would happen if I kept this one? If something bad, what other PSU would be recommended for my chip and everything else?

    Thank you :)
  6. It will probably work ok as it will be only loaded heavy a small percentage of the time.
    Like when you are gaming and such, thing is the long term quality is the question.

    For 60 bucks this is a good one.

  7. That is your typical low quality over rated PSU. May I suggest this as a replacement http://www.newegg.com/Product/Product.aspx?Item=N82E16817194038 or any other 500 to 550 watt psu from a reputable manufacturer like Corsair, Antec and like.
  8. Hmm. Well, what would happen if I continued to use my existing power supply? Would anything bad happen to any of my equipment, except for the power supply itself?

    I'd prefer to not have to purchase a new one if it isn't necessary--but am willing if it means my stuff will get toasted.
  9. Oh, and by the way, I don't plan on overclocking my videocard, if that makes any difference, heh.
  10. You might have a chance running a HD5770 on your current PSU but not a HD4890. Cheap PSU´s like that if overloaded have a tendency to take other parts out with them. The PSU is the single most important part in any system!

    Your current PSU could not only commit suicide but homicide as well.
  12. Fair enough. In both of your opinions, which do you think would be better for me?
    Corsair (550W): http://www.newegg.com/Product/Product.aspx?Item=N82E16817139004
    Antec (550W): http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016

    Either one, its up to you.
    Though i believe the Corsair comes with a 5 year warranty.
    I think they are both made in the same place anyway.
    ^^^^Seasonic i think.
  14. I would take the Corsair over a Antec Basic. If it was a Antec Earthwatts it would be a toss of a coin.
  15. Thank you guys so much! You've probably saved my computer's life, hah. I do have one more question, though. I'm getting my 4890 card in the next two days. Assuming I order this PSU now, it'll most likely come in two days after the card does. So, if I play with my new card on my current PSU for two days, would that run a high risk of killing everything? Is it advised that I just not play any games?
  16. I would not take the change for two days.

    It will probably be ok.
    You do know the 4890 requires 2 6 pin power connects?
    Not sure if your current PSU has them.

    Edit; if you dont play any games it will work just fine.
  18. I think it can also use a 6 pin and an 8 pin--pretty sure that's right--(which is all the Corsair has). My current one has....well ***, only one 6 pin. lol!

    Well, looks like I've got no choice now :) Thanks guys! I can only best answer one of ya, but you guys are both badass.
