Never cheap out on the PSU, if you have budget for R5 and an SSD then you should also have a good budget for the psu. Try the VS series from Corsair, cheap and reliable plus good warranty. Deepcool is shite
Your PSU is crap, I built a pc for my friend with that same PSU, it died the second we installed windows. Substituted it with a seasonic unit. worked like a charm!
