H61mgv3 Ver 8.0 Schematic
Based on the , this motherboard is designed to support Intel Sandy Bridge and Ivy Bridge processors (LGA 1155). Key specifications include: Socket: LGA 1155 Chipset: Intel H61 Memory: 2 x DDR3 DIMM slots (Dual Channel) Expansion: 1 x PCIe x16, 1 x PCIe x1 Storage: 4 x SATA II 3Gb/s ports I/O: USB 2.0, VGA, HDMI, Audio, LAN 2. Analyzing the H61MGV3 Ver 8.0 Schematic
Pay close attention to the Super I/O pinout to check for the "PS_ON" signal, which tells the power supply to start. Conclusion
Main power from the 24-pin ATX connector. VCORE: Usually 0.8V to 1.2V depending on the CPU state. VDRAM: 1.5V for DDR3 modules.
If the MOSFETs are receiving voltage (+12V) but no voltage appears at the CPU socket coils, the PWM controller is likely dead or missing its enable signal (
Intel LGA 1155 socket, supporting 2nd and 3rd Generation Intel Core i7, i5, i3, Pentium, and Celeron processors. h61mgv3 ver 8.0 schematic
Look for the timing chart. This tells you the order in which voltages (e.g., +3VDUAL, +1.05V_PCH, VCCSA) must turn on.
The PWM controller activates the CPU MOSFETs to deliver roughly 1.0V–1.3V. 2. Key Circuits and Components on Ver. 8.0
Controlled by a multi-phase PWM controller. Look for lines labeled PHASE1 , PHASE2 , and UGATE/LGATE connecting to the VRM MOSFETs.
