That psu, I have never heard of azza i would avoid them and get a more reputable make like seasonic, corsair, xfx, antec, cooler master. Its also way way over kill for that rig you wont even touch 500w.
^get that its cheeper, a better make and still has pleanty of room for upgrades and so on.
i think that cpu only supports 1333mhz but the ram should automagicly under clock it self to 1333 giving you a lower latency ram. So do get the ram but check it in the bios after building.
I dont like sapphire they some times require sapphires crappy custom drivers rather than the amd.com ones. But thats just my personal preference.
The 7770 is a good mid ish range card and should support dual monitors on desktop no problem but 1 monitor for gaming. I would consider saving up and getting a 7850 or a 7870 as they are really nice cards and well worth the extra cost.
Flux is right, you should get a better brand PSU like one of the ones he mentioned and with those parts even hitting 300W would be a stretch, but it's generally good to overbuy on your PSU a little bit, but not by that much lol.
I've changed the motherboard to a BIOSTAR TA970XE AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard with UEFI BIOS, and thank you so much flux, And by the way Commissar I know its pretty old but I love it and i'm kind of on a budget right now but was planning to upgrade to the fx-6300 anyways xD. Thanks for all the help guys.
