Re: Intel Desktop Utilites +3.3V warning Well I went ahead and put a new PSU and the above is the result. I looks like the old one is showing its age. At least it didn't fail catastrophically like previous PSUs in the past. I will keep it around as a spare in case of emergency since it still works.
What are the two voltages in the bottom? The memory controller thing stayed at about the same value and the other keeps going up and down over time both with the old and new PSU. |

| The left one is for the memory controller as you said. The right one is the voltage for the CPU itself. If it's dropping under load, you're seeing the effects of Vdroop.

Actually, now that I look at the before and after pictures, the CPU voltage fluctuation is probably caused by SpeedStep. When the CPU is idle, it lowers its frequency and voltage, reducing power consumption and heat. You can check for this by running CPU-Z and watching the core speed and voltage sections.
