Cheapest PSU for GTX 480

I currently have this: Rosewill RP600V2-S-SL 600W
http://www.newegg.com/Product/Produc...osewill%20600w
It has the minimum required W for GTX 480, but I read due to the fact it does not have + 12V 42A or greater it will not handle the card. Does anyone think it still may be possible?

If it's impossible, anyone know the cheapest PSU that will work? Although this PSU is just barely under W, it says 80plus and I think has higher +12V. Does it stand a better chance?


What exactly am I looking for when shopping for a psu to know if it meets minimum specs? Do I add the +12V or something?

  1. I highly recommend you to buy a new PSU. You have a very low end unit.

    As obsidian86 has said, the Seasonic S12II Bronze is a great option for 80$ (shipping included).
    For also 82$ (shipping included you have the XFX XXX Edition 650W (by Seasonic) which is modular.

    A bit cheaper, but already good option, would be the ANTEC Earthwatts 650W (by Delta) for 67$ (after MIR and shipping included).

    But, in my opinion, the best choice would be the CORSAIR TX650 650 W (by Seasonic) for 62$ (after MIR and shipping included).

  2. thankyou so far!

    would this one possibly work? OCZ600MXSP
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817341017
    I read this: "Dual 12V output can deliver up to 42A combined load", is that all I need?


    I am also needing a hard drive so it would be nice to find a newegg combo and that one i posted has a great combo.

    the corsair you posted also has a combo that would work but it is quite a bit more expensive, but still an option.


    *edit - what about this one? http://www.newegg.com/Product/Product.aspx?Item=N82E16817182200

    How do I know when I'm shopping through PSU's whicih ones will work? I think it has to be 42A at least, and that second one I posted says 50A for the 12v, but it only has one 12V and some I see have 2 or 3 at +12v20a etc.. do i add them up?

    No problem. The OCZ ModXstream 600W can handle a GTX480. 52$ is a good deal. Anyway, in my opinion, a CORSAIR TX650 for 62$ is a better deal.

    If you want a combo, I would go for this one: http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.492764. Both are great products.
  4. I really appreciate you letting me know what works and your advice, but unfortunately I am on a tight budget and have to go as cheap as possible.

    Would there be a reason I might need the OCZ ModXStream Pro OCZ700MXSP 700W instead? It's only $10 more but would rather not if i dont need it. The most components I would ever need to power is single 480gt, phenom II x4 950, 40gb ssd, and 2x500 samsungs f3's.
  5. Corsair and Seasonic are two brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty (in the USA).
  6. I am sorry I am not able to select the preferred brand and will have to opt for the 3 year warranty. I can't see myself not needing to upgrade in 3 years anyways.

    Please, I need to know the compatibility of the stated models with the components I listed. 600W should be fine, correct?
  7. No one wants to help the poor boy who can not afford the preferred brands...

    There are mainstream brands and products for a reason, I'm sorry i fall into that category, but this PSU recieves over 26 expert reviews (here) all satisfactory, close to 90% and with a 3 year warranty. As long as it is compatible with the components I listed it is satisfactory by my standards (not yours).

    Yes, the OCZ 600W you linked to will be fine with a GTX480

  10. Thank you very much for a straight forward answer Shadow. I do just want to confirm however because I am confused, I believe Nvidia's requirement is a single 42A 12volt, where as this PSU seems to have 2 25A 12 volts... I'm not really sure how that works?
  11. I hope i didn't stop people from checking the thread by picking a best answer already... oops

    That means you have a total of 50A on the +12 side. You'll be fine.
