Hi, i'm trying to build a PC for the lowest amount of price (PC Flipping), and I was supposed to get a GTX 970 but the used ones are currently overpriced. I found a guy with a R9 290x for $100 (CAD) and I already bought the PSU that was for the 970. Which is a DA500 from Deepcool. It's 80+ Bronze Rated. Is that enough?
