Is My PSU Powerful Enough?

Hi I'm just wondering if the PSU I have picked out: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016
is good enough to run the build I am trying out. I will have an XFX HD Radeon 6870 and an AMD Phenom II X4 955 BE. Also I plan on overclocking the CPU but not the GPU. Anything else you need to know?

  1. With 37A for 12V, you should be good to go with what you want :)

    But its quite expensive, you can find better ones for cheaper!

    edit: like this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371048

    48A for 12V and 5$ less

    edit 2: or get it from ncix, its on sale http://us.ncix.com/products/?sku=56788&vpn=HCG%2D620&manufacture=Antec&promoid=1244

    edit 3: Free shipping on both, so best get it from ncix for 60 :D You will be future proofed (on the psu side) if you ever want to upgrade or crossfire
  2. For a system running with a single Radeon HD 6870 graphics card a power supply with a combined +12 Volt continuous current rating of 27 Amps and with at least two 75W 6-pin PCI-Express power connectors recommended.

    Your Antec BP550 Plus 550W, with its combined +12 Volt continuous current rating of 32 Amps and two 150W 6+2-pin PCI-Express power connectors, meets the requirements.
  3. could not get much info from the antec website. seems like its one of the discontinued models. the amperage on the 12v rail is what i am concerned about it shows 2 12v rails and 22a each but that dosent mean its 44A in total so this psu may not be able to support future upgrades. not sure how much amperage the 6870 needs but you can see the supported psu list here

    Between this and your response to a paper clip test in another thread , you should refrain from posting responses to power supply questions.
  5. I couldn't edit my post.

    The current version of that model is rated at 37 Amps. The older version was rated at 32 Amps.
