    Default Power Supply question with GA-EP45-UD3P

    Hi There,

    In the Quest to set up a new machine

    I will use GA-EP45-UD3P
    but have with this Existing Power supply
    Cooler Master Real Power 550 RS-550-ACLY
    ATX12V 2.01 / EPS12V 2.1 550W Power Supply
    I pay at the time 120$ an try to find out a way to save some $
    It come with 1 (8pin EPS 12v)
    and 1 (4pin ATX 12v)

    I read That you need 2x 4pin 12v to be able to connect
    and enjoy a bit of overclocking....

    I also calculate that 550W is OK with
    E8500, Gt9800gtx+, 2x2gb ddr2 1066
    2 Hard disk, 2 DVD rw,and a few external UsB device...

    Your help needed....

    You may be ok.

    However that PSU only supplies up to a maximum of 30amps on it's 12 volt rails (360w) - which is on the low side for a 550watt PSU.

    Thank you 'VorLonUk"

    You Make me Worried with "May Be Ok"
    This 30amps looks Just enough.....?%$^%#@#@
    If I have to get one New PS what would be the best solution?
    I Need to keep My new Setup alive for 2 to 3 years....

    Well looking at EVGA and BFGtech they suggest around 24-26amps with a basic (9800gtx+) setup using a CPU such as an E4500 (bfg site).

    You may be ok with the PSU you have, but it could be cutting it fine when playing a demanding 3dgame and with a modest CPU overclock.

    Personally I like Corsair PSU's.
