Please use enter!

It's not that hard!

Anyway, i believe that is enough for that system. However i would go with 600w or 650w in case you're going to do future upgrades.

Henkjan1998 here is a really good power supply calculator you can use to get a basic gauge of how many watts power supply you need: http://www.extreme.outervision.com/psucalculatorlite.jsp

Here is a overclocked 3960x with a 7870 :http://www.anandtech.com/show/5767/capsule-review-sapphires-radeon-hd-7870-overclock-edition/4

As you can see it pulls 331watts from the wall under full tilt, the TX550 will do the job fine.

Yep - 550w would be fine for that but if your thinking about adding another 7870 in the future I would get a higher wattage
