Catchy title huh... so my upcoming build will be my first. Been researching for ages (about 2 months) before i bought my parts. Though i bought only one 4870 1gb i plan on added another in maybe 6months-year. For this reason i made sure everything was x-fire certified including my psu which is an antec earthwatss 650w (http://www.newegg.com/Product/Product.aspx?Item=N82E16817371015). The 4870 1gb needs 2x6 pin to power. my psu comes with 2 but wont i need 4 for crossfire. Im new to this so i dont understand modluar and maybe i can get adapters to make 4x6 pin plugs. please help explain and if this psu is not good enough can you reccomend ones that would be good for a 2x4870 1gb xfire setup. thanks
