I'd like to get the 750tx, but have one primary conern, the the 750 has a lot of noise in the 12v line comapred tot he the 650, but im not sure if it'll impact performace at all. efficiency is important too. 5 case fans, clarkdale overclocked, corsair h50, 2 hard disks, either radeon 5770, 5750, or 9800 gtx. the price fidd is only about 15$$ CAN, which make the 750 even more tmeping. any ideas.?
I have 750..Powerfull and stable.. have run two 5870 with x6 and no pobs at all..whichever suits your needs and budget, both good, if you think you will never have 750w parts then go 650, if you want a little wiggle room for future go 750!
I've decided to open up some more funds, and now im leaning toward the corsair 650HX, with up to 86% (tested) efficiency!!!!. Besides, i currentl will have a clarkdale for a longgg time oc'd, so no sli for me
As long as they are in tolerance, I do not worry much about noise levels on the 12 volt output. It's mostly going to be converted and filtered more in the motherboard and video card power regulators. And fans and drive motors really do not care.
