My psu only has 6-pin connectors but a few of my components only have 4-pin connectors. the last time i used a 4-pin to 6-pin connector it shorted my motherboard, so im hesitant to try this again... is it gonna be ok to use one of these (http://www.newegg.com/Product/Product.aspx?Item=N82E16812887001&cm_re=4-pin_molex_to_6-pin-_-12-887-001-_-Product) to connect a water cooling system, a case light, etc. directly to my psu?
