Hello guys ! So i own this configuration: CPU: AMD A8 3870K 3.0GHz, MOBO: MSI A75A-G35, 8GB DDR3 RAM Hyperx Fury Blue at 1600mhz, a normal 500gb WesternDigital 7200rpm HDD and a 500w PSU from SAGA 2 with 80% certification, and a few days ago i got a MSI GTX 1080 GAMING X+ 8GB GDDR5X 11 Gpbs and my pc seems to not boot when GTX 1080 is inside but when booting on integrated graphics it boots normal so i want to know what PSU should i get cuz i had another post and somebody told me that the boot problem must be the PSU 100% and i want to know what PSU should i get for my sistem ! Also, in the near future i will upgrade to an i7, a new MOBO, and 16GB DDR4 Ram !
