I'm looking to get a new psu because my current extreme 600 is a very poor one I have been told. I want to know how many watts I need. I'm looking at the corsair 650w 80 plus bronze or the 550w verison but I don't want to waste money (energy related). I currently run a i5 3570 3.4 gb 16gb ram ddr3. 1tb hard drive. gtx 950. no overclocking of any kind. Also there is the fan that would be pointing up (north) to my video card which has its fan pointing south. there are probably a few inches apart. my current one only has one pointing out of the fan. is that ok. it seems like they would keep pushing crap into each other if that makes sense.
