I have the chance to get a radeon 7770 1gb gddr5 ghz edition or a 650 ti. The price difference is 20 dollars (the 7770 is 99.99 and the 650 ti is 129.99) is the performance differance enough to buy and will a 400 watt psu run it? Thanks in advance also mostly playing in 1280 by 1024 to 1680 by 1024
650ti = 110w/12v=9.2a
fx 6300= 95w/12v=7.9a
your mobo should only draw 6a at max load
this gives you a draw of 23.1a on the 12v rail at max load without an overclock
the cx 430 pushes 32a with a variance of .8a so 31.2a
this psu should support the card with your setup but beware that cx series has had issues lately so as you push closer to that 31.2a. just a heads up. i would try it with your current setup and if it runs it fine your good, it is rated for it however if you have issues it may be due to the poor quality of that psu.
