Need a bit of help Regarding PSU and GPU

To make it simple...

I own one of these (PSU): http://www.newegg.com/Product/Product.aspx?Item=17-339-022&SortField=0&SummaryType=0&Pagesize=10&PurchaseMark=&SelectedRating=-1&VideoOnlyMark=False&VendorMark=&IsFeedbackTab=true&Page=2



Im'a buy one of these (GPU): http://www.newegg.com/Product/Product.aspx?Item=N82E16814150561

Current PSU: X Power 585
GPU Im'a buy: Radeon 6870

Apperantly I need a 6-Pin Pci Adapter.. I keep getting diffrn't answers from a diffrn't forum and it's bugging me. I need a real answer..

Can anyone link me to the adapter/connecter i need?


Edit: Some guy posted: Your current PSU's 12 volt rail is only at 18 Amps, it doesn't have enough power to supply the GPU and processor together. :??:

Is that true ^ :(


Thanks.

*Im excited. Switching from Radeon HD5550 to 6870... Should I expect a huge diffrence in FPS in games?

    Just buy a new psu : http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027
    You'll have to buy a new one.

    And switch the gpu for this one : http://www.newegg.com/Product/Product.aspx?Item=N82E16814150642

    If you can, it will have better performance and lower power consumption and it's from the newest amd generation (better performance dx11)

    One of these is usually included in the box with your graphics card.

    Yes, this is true. You will need a new PSU. The one linked above should be adequate.

    A huge difference? Maybe not huge, but you should certainly see a very noticeable improvement. Going with the 7850 as suggested would further increase that.
  3. Sounds like a plan. $40 PSU and that 7850 looks amazing... I am really excited.

    Also last question really, I feel so dumb. will the 7850 fit in this my case? :

    http://www.newegg.com/Product/Product.aspx?Item=N82E16811129042

    And 2.1x16 = 3.0x16?
  4. Yes it will fit, and about the pcie 3.0, any gfx card with pcie 3.0 is 100% compatible with pcie 2.0/1.1/1.0 slot, the most important thing is to be at x16.
    And with 0% performance loss vs pcie 3.0 slot, see this : http://www.hardocp.com/images/articles/1341219566Ew8yr7oTVd_2_3.gif
  5. Mid tower will probably be quite a squeeze, but it should fit. Just be patient with it.

    For all intents and purposes yes. PCIE 3.0 = 2.0
    Unless you're running an Ivy Bridge, PCIE 3.0 cannot even be utilized and instead defaults to 2.0. And even with an Ivy Bridge, at this time there is negligible gain between the two specifications.
  6. You guys are the bomb. Thanks so much everyone was just straight forward. I like this website. I wish i can select all as best answers. I am so excited to upgrade..Wish me luck :)
  7. So I offically ordered what djagorino posted. I didn't order the 6-pin adapter because apperantly I don't need one (Refer for previous posts). I am excited.

    I have a few other questions.
    1. Is there any possibilities of problems I might run into?
    2. How long does it take to recieve the Mail-In-Rebate cc's?
