My PSU went out last night after a power outeage, having run like a champ for 4.5 years (seasonic 500w) on my athlon x2 3800, 7800gtx system (recently upgraded to a 9600gt). I just went down to Best Buy and purchased an Antec Earthwatts 650w PSU for $107 after tax(~$20 over newegg), to confirm that it was in fact the PSU and my system fired right up. However, my thinking is I'd prefer something modular since my antec p180 was a little on the cramped side and possibly something a bit higher grade for a possible upgrade to i7 or c2d in the near future. What do you guys think would be the best option, keep it or upgrade to something like the Corsair 650HX and take this one back?
