Asus GTS450 TOP PSU requirement!

Hello,
I just bought an ASUS engts450 TOP, I want to know whether my current PSU is enough or do I have to upgrade...?
Current PSU:
Coolermaster 460Watt 12V/18A
PSU details:
http://www.coolermaster.com/product.php?product_id=3686&category_id=30

Edit:
The reason why I'm much worried about my current PSU is that the version I had (Asus 450 TOP) is DirectCU edition which has copper heat sinks on it.... so it may consume more power!

  1. You will be fine the card only needs a single PCIE connector which you have. Also you have +12v/26A not 18A.
    I have the same Power supply powering my old rig which is in the daughters room hapilly running a 4850 which is about the same power wise.

    thanks! I'm not good about PSUs.
    You said it is 26A but my PSU box has 18A written on it, dont know more about it...!

    In the link you provided it says there are 2 +12v rails, each says its 18A. Below those is a wattage 312 which is for both rails.
    Each rail can provide 18A on its own but they both cant provide 18A at the same time 18+18 =36. This is because there is only 312 watts available to both rails to share, the math is, Watts divided by Volts = Amps. so 312 divided by 12= 26 A shared across both rails. Some PSU's can provide enough for both rails to provide the stated amount but quite a few cant like yours.
