I'm looking for a new power supply to replace my current 500w one, in order to run a GTX 770 or R9 280X. I've narrowed it down to 3: http://goo.gl/huP85u http://goo.gl/VwnJR9 http://goo.gl/iyJnPq. I know that they are all decent quality but I'm just wondering which will last me the longest, be easiest for cable management and be the quietest. Thanks.
