Advice on replacing power supply

I've had this computer for about 2 years: http://www.newegg.com/Product/Product.aspx?Item=N82E16883229221 only adding on another 6870hd card for crossfire and replacing the ram.

Since I got it I've been experiencing constant freezing/blue screen issues like the numerous other people that have gotten cyberpower pcs. It turns out the crappy Xtreme Gear Psu may be causing it.

I need advice on what new power supply to get and how difficult is it to replace the power supply.

    OK - give me a couple minutes.
    Good news is you won't have to spend $150.

    You are using 2 - 6870's in CF right?

    Hi again - realhardtech on their PSU req for 2 6870's in CF is 900w.
    You don't need that much, you could probably get by with a
    quality 750w unit, I'm going to suggest at least one 850w unit
    to be on the safe side.

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817151108 nets to $120

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817151102 nets to $140

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817139022 nets to $130

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817182084 nets to $110

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817139021 nets to $100

    Any of these will power your sys with 2 - 6870's in CF. My personal pref of these
    is the Seasonic X-850

    Hi - not difficult at all. I consider myself lousy at mechanical stuff
    and I changed mine. There are tutorials online, there are also
    demo's of how to do it on you tube.

    Here is the one I used:

    It's all good, the 850 is perfect for future upgrades I may get.
