I need some quick help with my new motherboard, located here: http://www.cclonline.com/product/73547/NoMfgCode/Motherboard-Bundles/CCL-Alpha-Advantage-Motherboard-Bundle/MBB-AMD-HIGH1/ and I have a Antec 520w power supply, the motherboard is 8 pin but my power supply has 2, 4 pin connectors, is it possible to plug the power supply in? do I need to buy a new power supply?
