Dell Studio 540 PSU and GPU upgrade

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! :)

    Thank you much for the link. So would this psu be able to power the chosen GPU and have both of them still be compatible with my computer?
  5. Should work , your computer appears to use standard ATX PSU.
