The positive system voltage sets which can be monitored include:
• CPU core voltage: 1.3 V ~ 3.3 V, according to Intel specifications.
• Termination voltage from CPU to chipset: typically 1.5 V.
• Chipset voltage: typically 3.3 V.
• Main voltage: +5 V, +12 V.
The negative system voltage sets which can be monitored include:
• Main voltage: -5 V, -12 V.
