    Realistic PSU wattage for my system

    All

    I am running a 680i based system and will be dropping in a single 8800GTX this weekend. I have an important question...will an M12700W Seasonic PSU be powerfull enough for me to upgrade to Sli 8800GTX cards....my specs include:

    Asus Striker Extreme
    E6600
    Dual Raptor Xs in RAID 0
    Single Maxtor 300gb HDD
    X-fi fatality
    Single CD/DVD rw combo
    2gb ram
    DDC Ultra water pump

    I know the 700W will be fine with a single GTX how will it fair with 2 of these beasts.....

    I'd say you'd be ok with 700w as long as you don't want 8800 SLI

    Something like an OCZ Gamextream or an Etasis 750w would be stable and nice

    How flaky? I used what they calculated + 100W (you dont want your psu running at full load all the time anyway) - should I have been more conservative?

    I reckon the Seasonic 700w will be fine for that setup.

    If you're gonna spend &#163;600 on two 8800's for SLi you might as well got the whole hog and get an 850-1000W PSU

    agreed^^ but also, scan quite often have the galaxy PSUs on today only and i think the 850w one comes out around 168 quid, which is only a few quid more than the seasonic.

    Lo D

    The INQ have a good story on PSUs and SLI (plus overclocking).

    http://theinquirer.net/default.aspx?article=36066

    I knew the 700w would work fine, but still I would suggest you future proof yourself - may as well as the prices are very similar.

    I've not heard great things from OCZ. I've come to learn and read that Tagan and Seasonic are "the" PSUs to buy.

    Oh yeah, PPC are better if not the best PSUs available, but that's the &#163;300 for the one Mullet was looking at.
