I wanna buy a SAPPHIRE HD 6790, I have 450 watts PSU, will it work good? Please do not ask to upgrade the power supply because I'm only able to afford a GPU hardly.

Please list the make and model of your psu. You may not want to hear it, but if your psu is a cheap poc, many here will advise an upgraded psu before recommending any gpus. Just because it has 450W on the side, doesn't mean that that's what it's capable of. Sorry, but that's just the way it is.
Good luck.

This is the closet gpu i could find like you want:

It takes one 6 pin pcie power connector. The gpu shouldnt draw that much power, so give you PSU a try at your own risk..
