Maximum PC

Okay guys so I am on the last step before purchasing the parts I need. As I said in another thread I am somewhat of a noob on building computers and it is my first time build. Thanks to the people who have helped me out and gave me advice. I am not a hardcore gamer and just looking to play few games (Arma 2 DayZ mod and maybe some counter strike). I am also not looking to spend a lot of money.

Here is what I have already
- case
- harddrives
- optical drive
- power supply (400 Watts, few years old, I think I need a new more powerful one right?)

Here is what I am planning on getting

cpu:

graphics card:

memory:

depends, what brand (make, model), if it is a reliable ATXv2.x+ / 80+ unit it should be just fine, most i3/7770 builds will never see over 200W from the wall IRL, and most PSU calcs put it less than 300W recommended. If you can post that or a pic of the label, that will let everyone know.

cheers

edit - here are a couple of good deals / examples of decent units for the price I have used recently

Antec NEO ECO 400C 400W $40 + $5 shipping
CORSAIR Builder Series CX430 430W $45 w/ $10 MIR


I would just go for the ASRock it's good enough and $10 less
