    These are without doubt, the best value PSUs that you would require to also give you a bit of headroom should you upgrade further again.
    They will all run anything but the MOST HUNGRY machines around.
    Three of them are under £70 and 1 under £80.

    Corsair 620 watt hx series for £100. Mine is actually broken but

    I think the Seasonic PSUs are great. Pretty quiet and efficient. Don't go for anything under 600W. My two cents.

    I would say a 600w Seasonic S12 would be a good bet, though if you want a second 8800 later look at the 750w M12 from Seasonic

    Quoted for truth.

    Think of it as a Seasonic+

    For guidance on purchasing PSU have a look through Jonnyguru's website.
    http://www.jonnyguru.com/

    Estasis make Silverstones PSU's so whatever review you read on Silverstone and want to purchase one buy the Estasis equivalent and save a few bob.
    FYI I have a similar system cept for the mobo AW9D-Max and it runs rock steady with a 700 Watt Epsilon from FSP.

    Any half decent 500W PSU should power that with ease.
    600W is nice, but an overkill

    Tagan aren't too bad either.

    Also, I can't help but feel the 768Mb XFX 8800GTX Extreme XXX will be wasted on the Acer 17" LCD lol.

    If I understand you correctly, you are suggesting not getting a 600w PSU because it will cost you more?


    600w units are no less efficient than 500w units, if a computer doesn't draw the full 500w then it will cost the same to run regardless of which one you use.

    It is definitely overkill for a 17" monitor. You'll need 24"+ to make use of that 8800GTX. Otherwise I'd recommend getting a 7900GS/7950GT as your graphics card (or even stick with your 6600GT and see if you are happy with 3D performance first.

    I agree with arthurleung, and if you wanna overclock the CPU (which you should ) you'll need a different motherboard.
