As I go to leave my PC on overnight to download some stuff it occurs to me my mighty little Corsair HX-620 (Seasonic built from memory) PSU has been powering my various rigs for approx 10 years and powered an extraordinary amount of gaming and encoding in that time. I suppose my question is should I consider a pre-emptive replacement or just keep on going until it finally gives up? Is this risky to other componentry? My system isn't enormously hungry. Now pretty old 2600K @4.0Ghz / GTX970 / 16GB DDR3 /1X SSD and 3X HDD's and a few fairly low RPM 120mm fans.
