I am about to order a new case for myself because the one I have is to small. I think I may need a new PSU but I am not sure. I calculated about 500W needed but I just want to be sure.

More about bigger power supply
  1. Yes I think you'll be ok with that psu.

    I'd take the 1200 over the HAF932 but the HAF-X over the 1200.

    I'd take this over both of them -
  2. I am really digging the HAF-X :D
  3. If thats the one that does it for you then get it.

    You'll be glad you did everytime you look at it. ;)

    What about its crazy looking brother -
  4. lol thats a cool case - i wonder how much nvidia paid them :)
