I've recently treated myself to a new power supply, and finally retired my old Corsair HX750W. Yes, the old 'W' version! As this one has been so trouble free, I have bought its modern equivalent, the HX750i When I looked at the old one, everything seems absolutely fine, no bulging caps or funny smells. Considering its had about 12 years of constant hard use, I was very impressed. I tested the power usage using a socket meter comparing the new to the old. With my PC at idle, I was consuming about 118 watts with the old HX750W. With the new HX750i, I am consuming about 113.5 watts. So not a massive difference considering the new PSU is Platinum rated and the old is Silver. This power supply has always had a fairly hard life. On the CPU side, it started life powering a heavily overclocked Q9650 on a X48 platform, then a heavily overclocked X5675 on the X58 platform and now a overclocked but under-volted E5-1650V2 on the X79 platform. On the GPU side it has powered a GTX280, later a GTX480, GTX770 and now a GTX980ti. So all fairly high power stuff. The only reason I changed it out was that it was the oldest part of my system and I wanted some peace of mind. It does beg the question however, how long is it safe to use an old power supply like this and is anyone else still using one this old? I'd love to run some tests on my old PSU and see how the voltage regulation had held up and see if it can still deliver its rated 750 watts.
