You're chilling with that ssd, if that cpu works i cant find a reason why not to buy it if its under avarage price of a new one

Never heard of that psu tho.. im not that much into psupplies but check psu tier list . if its in top 3 tier you are good because this is kinda high end although you forgot to list gpu
