    Looks like I might be in need of a new PSU

    People from the lan will remember after installing my second vid card for SLI I couldnt get the OC I had before and I had to clock the CPU back.
    I've just gone on ExtremeTechs PSU calculator and put in everything in my rig including the HDD I broke and input the CPU speeds / voltage I was running begore and it recons that system will suck 555 watts , No wonder my 500 Watt PSU cant take it.
    The think that shocked me is that it said my CPU was taking 190 watts of Juice, I thought they only took about 120 watts, no wonder my calculations are off :/
    With the settings im running atm apparently its taking 524 watts, now the PSU is 500 watt but can peak at 550 so should be ok for the mo but looks like its taking a proper hammering .

    What I was thinking to jsut be sure the PSU isnt up to the job is powering one of the vid cards from a second shuttle PSU I have, now the issue with that is I know how to power it on without a motherboard but I dont know how to power it on at the same time as the antec, would powering on the antec then the shuttle one hooked up to the vid card blow the card?
    If so how do I get both PSU's to come on at the same time?

    And if I do manage to do that and it works fine overcloked then what PSU should I go for?, apparently ones with single rails but with shed loads of amps on the rails are the ones to go for?
    Personaly I have always thought that dual / multi rails are the best as long as theres enough amps on each rail?

    One thing im noticing with the PSU calculator though is that it recons a FX60 draws the same power as my Opteron 146 at stock speeds? surly that cant be right, they have the same core voltage so maybe its getting the wrong data from there?

    What PSU do people recomend for my system?, Im running a dual core Opteron 165 hopefully at 2.6GHz again if the new PSU sorts the issues, with 2x 256mb 7800GTX cards, 2 250gb hard drives, 2gb ram and 2 optical drives.
    Looked at the 700 watt FSP PSU but I dont think theres enough amps on each of the 12v rails as theres only 15 amps, might just be allright for now but prolly not for future vid cards?
    Am I better looking at a dual rail PSU with more amps? one rail for CPU and the other for the vid cards?
    Damn picking a PSU is so confusing these days, I remember when all you had to know was that more watts = better :s

    I think you should look at Seasonic S12-600 and FSP FX600-80GLN and if you want bigger, Tagan have lauched a pair of monsters at 1000W and 1100W.......

    CustomPC did a 'How to' some time back of setting up a dual PSU rig.....

    They did a comprehensive PSU Lab in October '05 check out http://www.pcpro.co.uk/custompc-labs.../products.html

    Hmm... well the dualies do draw a bit of power according to anandtech ;

    http://www.anandtech.com/cpuchipsets...oc.aspx?i=2668

    And now your running SLI that is going to draw quite a bit of power as well.

    I would really recommend a 580w & above, esp as I know you tweak the hell out of everything including your nipples (supplied by zalman of course )
