Don't use that PSU. It has only 25 amperes on 12V rail, which means 300 watts of power for your motherboard, CPU and graphics card. Since GTX 560 Ti peaks at 200 watts under load, that PSU might explode under that load. Please, save yourself some trouble and get a power supply like this one:http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027
It's at $39.99 after rebates.
