SeaSonic S12II 520W vs Antec NeoECO 520W vs XFX TS Series 550W power supply

I am confused about which Power Supply should I choose from my list. The specs that I am using is AMD CPU, HD 7870 graphics card, Coooler Master 212 EVO, Gigabyte motherboard, etc. The current PSU that I am using is not too good and therefore I am looking to change it as soon as possible. I am looking for a PSU that will produce less noise under load, pure power, small amount of wires and not more. So, which one should I choose among SeaSonic S12II 520W or Antec NeoECO 520W or XFX TS Series 550W power supply. Thanks

The best power supply would be the Seasonic brand and they also have a very good repuation for building quality products. The Seasonic S12II 520W PSU is very quiet and it does the job pretty fine. I was previously using an old PSU which came in the computer case and it used to get noisy specifically when it was going to end its life. Its very quiet. I have done a lot of research before buying one and found Seasonic to be a reputable brand.

I have also read from many stores that Seasonic is makes really the best quality Power supplies and the SeaSonic S12II is made up of a better quality and it is also modular. Normally, anything made by Antec or XFX are basically Seasonic, so all the power supply are made up of qyality pieces. You just have to trust all those three brands that I have listed in my post. Just check to make sure which one is cheape than the other. Hope this helps you out.

The Antec NeoECO 520W power supply is also equal to the SeaSonic S12II PSU. You will not get a quality unit like this and it is worth if you are getting it at a lesser price. This Antec psu is very dependable and pretty much strong as well. I had purchased it when it was on sale and the rating of this PSU was also very high. It gives more than enough power to my gaming system. Although this psu is not a gold-certified, but still it is definitely not bad at all.
