Чтобы хоть немного разобраться в питании nForce3, приведу кое-какую полезную информацию.

Цитата:
The nForce3 250 Gb has sixteen power planes...
Functional blocks of the nForce3 250 Gb use separate power planes.

nForce3 250 Gb Power Planes
Signal Voltage Definition
 +1.6V  1.6 V  1.6 V Core Power. This voltage powers the nForce3 250 Gb core.
 +1.6V_DUAL  1.6 V  Auxiliary 1.6 V Core Power. This voltage powers the nForce3 250 Gb core power management circuitry.
 +1.2V_HT  1.2 V  1.2 V HyperTransport Power. This voltage powers the HyperTransport Interface.
 +1.5V  1.5 V  1.5 V AGP Power. This voltage powers the AGP interface. The nForce3 250 Gb only supports AGP3.0/2.0 signaling levels and therefore this voltage must be 1.5 V.
 +3.3V  3.3 V  3.3 V Power. This voltage powers the I/O interfaces to 3.3 V peripherals.
 +3.3V_DUAL  3.3 V  Auxiliary 3.3 V. This voltage powers the power management circuitry interfacing to 3.3 V peripherals.
 +3.3V_PLL  3.3 V  3.3 V PLL Power. This voltage powers the internal PLL.
 +3.3V_PLL_DUAL  3.3 V  3.3 V PLL Standby Power. This voltage powers the internal PLL in power management states.
 +3.3V_USB_DUAL  3.3 V  3.3 V USB Power. This voltage powers the two integrated USB controllers.
 +3.3V_VBAT  3.3 V  3.3 V RTC Battery Back-Up Power. This voltage powers the battery backed-up real-time clock.
 +5V  5 V  5 V Power. This voltage powers the nForce3 250 Gb I/O pads from 5 V peripherals.
 +5V_DUAL  5 V  Auxiliary 5 V. This voltage powers the power management circuitry interfacing to 5 V peripherals.
 SP_VDD  1.6 V   1.6 V Integrated SATA Power. This voltage powers the integrated SATA core.
 SP_VDD_3P3  3.3 V  3.3 V Integrated SATA Power. This voltage powers the integrated SATA logic.
 VDD_SATAD  1.8 V  1.8 V External SATA PHY Interface Power. This voltage powers the external SATA PHY interface.
 V3P3_DEEP  3.3 V  3.3 V Deep Sleep Power. This voltage powers the power button, deep sleep, and wake logic. This signal is only used for mobile pplications. This signal MUST always be connected to +3.3V_DUAL.
