Reccomended Psu and case?

[plopyer10]

Ok so i'm in the market for a new psu and case. preferebly something under 150. I need something to power my gtx 550 ti because the current psu I have is very weak...unless you guys feel different! I know I need a new case however because it only has 1 fan and I have semi expensive components I need to keep safe.

Your psu has enough power for your build. You could use a 400w psu. This is a good case that comes with four fans and as 3.0 usb antec one http://www.newegg.com/Product/Product.aspx?Item=N82E16811129182
But if you want a more efficient psu then you could get this one pc power & cooling silencer mk iii 500w http://us.ncix.com/products/?sku=65318&vpn=PPCMK3S500&manufacture=PC%20Power%20%26%20Cooling
500w is more than enough power for your build.

It would be better to get a more efficient psu. The one I posted first would be best but you could go with this one to save a little pc power & cooling silencer mk iii 400w http://us.ncix.com/products/?sku=65317&vpn=PPCMK3S400&manufacture=PC%20Power%20%26%20Cooling&promoid=1381
