I'm planning to buy a new psu for my rig(config in my siggy and a few addon cards wifi card and tv tuner). I have some psu's in mind cooler master extreme power firstname.lastname@example.org and email@example.com. I need to know if the real power 460 is worth 1k extra over it's extreme series counterpart 460. The diff as far as I know are >80% efficiency,active PFC and max output could go upto some 530w. So is it worth that 1k extra or should stick to extreme power 460 or 500. Suggest me a good one. Also are there any other good alternatives. Max budget is 3k for psu. I need a new 8GB flash drive too with good write Speeds. I'm currently using sandisk cruzer micro 2gb and I'm quite happy with it's speeds but the problem is availability of sandisk seems to be an issue here. So suggest some good 8 GB alternatives with good write speeds.
