Hello, I'm new to the forum and look forward to helping out where I can. I've been working on/building computers for over ten years in my spare time. I've recently, however, ventured into something new which I'm not 100% knowledgeable about. I have a pny 9800gtx+ in my computer now and plan on running 2 in sli. I'm not sure if my current power supply can handle it or not.. its a coolermaster 600watt PS which is rated for sli, but these are large cards and some of them even require two 6 pin power connecters. So any advice on this would be much appreciated.. ty
