Will a 650w psu be enough for what i want

hi im getting either a 7850 or a 7870 for xmas of my rents( i think they are getting me the asus radeon 7850 but im not sure they wont tell me i just sent them a load of links for 7870's and 7850's) and i was just wondering if a 650watt psu is anuff to cover this (plus i already have an amd quad core 3.4ghz,2x4gb sticks of ram, 2 harddrives, arctic cooler pro 13 and 2 case fans) thanks :) cant really afford more then a 650 watt so i hope this is ok. the one iv picked for my price range is http://www.amazon.co.uk/Fractal-Design-Integra-Efficiency-Supply/dp/B009LHF4HC/ref=sr_1_1003?s=computers&ie=UTF8&qid=1355493313&sr=1-1003 cant afford any more then £60 . is the psu iv gone for also a reliable make? thanks guys :)

    or theres this one which looks good http://www.novatech.co.uk/products/components/powersupplies/ocz-zs650w-uk.html
  2. The 650w OCZ power supply will be quite adequate for your system.

    Even a quality 500w power supply will be better than a 800w generic brand power supply, just for future knowledge.
  3. I would go with Seasonic. Very good psus. A 520w model will work just fine, but they do have an affordable 620w model too.
  4. well go an ocz 650w zs series psu and my mum bought me an asus radeon 7850 it looks a beast. only thing :( isnt working. i removed all the drivers from my computer to do with the last gfx card and shut down the comp i then placed the new gfx card in and connected the moniters but :( no picture. tried all the connections on the gfx card nothing. is there anything that i could be doing wrong. what drivers do i need to make sure are rid really gutted man been looking forward all day haha

    my specs are:
    mobo:Gigabyte GA M68MT S2P
    ram 8gb
    cpu : athlon 270 3.4ghz (getting upgraded in a couple of weeks to a 3.2 quad)
