i have a sapphire vapor tri x r9 280x. but then it has a psu recommendation of 750 watt psu. but then i use the cm psu calculator and it says that only 515watt is needed. what watt of psu i will buy?
and about my casing i am planning to buy a h440 case but then i dont think my gpu will fit in that case.
thanks and sorry for my bad english. Haha
