Been chatting with my son and he's seriously thinking of updating to Z390 when it lands and dropping in a 2080ti. He recently bought a new case, Corsair 500d RGB, ( I think that was it ). I have just looked on my old orders and back in November 2013 is when I bought his current PSU, the Corsair RM 750. So this makes his PSU 5 years old. To me this sounds it could be coming to its end of life expectancy. I have had a couple of cheapo PSU's fail on me over the years without any major problems but I have read that if a PSU blows it can take other components with it. Is this fact or fiction ? Spending good money on new bits would it be advisable to buy a new PSU to replace a five year old one ?
