Hello, This is my first question here, so please forgive me if I placed this in the wrong place or whatever. But anyway, what I want to do is upgrade my graphics card. But with my stock 540 PSU it's only about 350w. I have a few PSU's in mind that i'd like to upgrade to. A link to one of them:

http://www.amazon.com/PSAZ-650B14-Dynamo-Power-Supply-Black/dp/B002KCNYWW/ref=sr_1_1?s=pc&ie=UTF8&qid=1376001842&sr=1-1&keywords=psu+650w

Would that one be compatible with my computer? Then for my GPU I was thinking of upgrading to:

http://www.amazon.com/XFX-DisplayPort-PCI-Express-FX775AZNP4-FX-775A-ZNP4/dp/B007Z3T5JC/ref=sr_1_2?s=electronics&ie=UTF8&qid=1376001904&sr=1-2&keywords=radeon+hd+7770

BUT would this be compatible with my chipset?

If neither of these would be compatible, what would be a good, cheap psu that would handle a great gpu that is under about 150? I game, if you couldn't tell, but not hardcore WoW and stuff like that. Just basic stuff like Minecraft, CS: GO, LoL, CoD 4, etc. So it doesn't have to be *BOOM* All expensive and fancy and stuff. Just something that will give me decent fps and something that won't cause strain on my computer. Thank you so much in advance! :)

Okay, thank you so much for all of your help! :) I sure hope that my rig will have a great improvement after I apply these changes.
