What in my PC would be on the 3.3V power connectors?
I'm getting some minor (inside 10% voltage fluctuations) whenever I run CPU/GFX/RAM intensive software. I'm not sure what might be using the 3.3V channel that's reporting the issue so am asking for some help so I can try and find the source of the issue.

The CPU and RAM would more than likely be drawing from the 3.3v, with motherboard converting to the proper voltages for them. PCIe graphics cards should draw from the 12v, IIRC, but AGP will draw from the 3.3v or the 5.0v, depending on the version.weemadando wrote:I'm getting some minor (inside 10% voltage fluctuations) whenever I run CPU/GFX/RAM intensive software.

Edit: Wikipedia states that the PCIe 1.1 spec calls for low voltage differential signaling (LVDS!), so its also using the 3.3v. (Link)
Artillery. Its what's for dinner.
