Hi there. I have an i5 3470 @ stock (77w) paired with R7 240 2GB DDR3 (45w) and 8GB DDR3 1333 Mhz ram.The GPU is also overclocked , 30% to be exact. I'm thinking about replacing it with a GTX 1050 Mini 2GB (75w). I don't think there will be any problem because it's just 30w more. So will I be fine ? Here's the pic of the 400w generic PSU : https://imgur.com/gPtzFni
