hello I recently ran into an issue with my rig resulting in me having to buy a new psu. Someone on here told me to go with the SeaSonic M12II 620watt psu. I just wanted to know what is the major difference between that one and the Antec HCG M Series HCG-620M? I only ask because newegg is having a sale on antec psu's for 15% off so if there practically the same I'm going with the antec one LOL. Any advice will be greatly appreciated thanks ^^
