I am sure it varies from model to model, I know I didnt get a 550 watt power supply on sale for < 50$ becuase they were being nice (although I just saw a 500 watt ultra lsp with the 131mm fan and lifetime warranty on sale for 49$ soo....)

I dont know much about the other ultra products, bought a heat sink from them its nice, they have cases too, but power supplies with lifetime warranties is a good start to make me want to look at more of their stuff heh
