My friend said he has a amd cpu. I think it's a lower end one. He said he just got a new PSU and its 400watts.

He wants to buy my asus gtx 550ti from me for $75. Is 400watts enough for his AMD cpu and my gpu.
-im assuming he has a dvd rom and other basic stuff. Like a full atx mobo

Also, will testing to see if it runs ok with my gpu installed hurt anything?
 
Solution
Depends on what 400 watt PSU, I've seen a number of '400' watt PSUs which awere 400 PEAK, and for continuous use wer like 275-300. Want a good 400. with at least 24 AMPs on the 12 volt rail
