I'm almost done getting the parts for a new build. It's going to be E6600 with P5W DH and x1900xtx. I plan to overclock, and maybe get crossfire later on. I've been looking at the Corsair 620 the seasonic S12, and the upcomming M12. I've read seasonic makes the corsair, so the question is should I pick up the Corsair now, wait for an M12, or get the S12 and ditch modular PSUs?
