System check/Last minute questions

Ok, I am getting ready to pull the trigger on buying my components. Can anyone look them over too see if everything is a-ok?

Also, the price the 7770 is listed at there is also a 6850 and 6970 around that price range. According to Tom's graphics cared hierarchy chart a 6850 is higher than a 7770 but I see the 7770 reccomended alot. Should I go with what I have or what?

Another question is, will the PSU I have picked out be capable of running everything? I plan on using my old WD Caviar Blue 320GB HDD.

CPU: Intel Core i3-3220 3.3GHz Dual-Core Processor ($129.99 @ Newegg)
Motherboard: ASRock H77M Micro ATX LGA1155 Motherboard ($69.99 @ Newegg)
Memory: Corsair Vengeance 8GB (2 x 4GB) DDR3-1600 Memory ($38.99 @ Newegg)
Video Card: XFX Radeon HD 7770 1GB Video Card ($137.55 @ Newegg)

PSU: Enermax NAXN ENP450AST 450W ATX12V Power Supply ($44.99 @ Newegg)

Total: $376.52 + $44.99 = $421.51

  1. I'd get the 7770. And if you have a Microcenter nearby, they offer $50 off the mobo if you buy an i3-3220 or i5-3570K.
  2. So the PSU should power it all? I dont plan on over clocking. And I wish i had one nearby, but sadly I dont.
  3. I'd get the 2120 which is a bit cheaper. The PSU is OK, but the Corsair 430w is about $25 and it's very good quality.
  4. The corsair 430 will work even though the card says "Minimum of a 450 Watt power supply."?
  5. They just say that because there are some really bad PSU's that deliver half the power they say. An i5 with a 7850 will use 350w, so an i3 and 7770 will use very little energy.
