Page 63: Appendix
APPENDIX I Subject 1: Regarding the Application of 3-Phase or 3+1 Phase Power Supply Mold As a result of the increasing power consumption demand from many AMD CPUs in current market, we suggest not to use a CPU that demands more than 65W power consumption at work for an AMD CPU compliant board that comes with power supply design as 3 phase or 3+1 phase mold and MOSFET design as working in High SideX1 and Low SideX1 mold so as to avoid MOSFET getting burned or other phenomena like a... - Page 64 for CPUs that demand 125W or 140W power consumption. Subject 2: Suggestion on choosing electric fan Both the amount of electric current to MOSFET and the heat produced from the motherboard go up as AMD’s CPU power consumption increases. In this case we recommend users select a CPU fan with air outlet towards MOSFET so that CPU fan can carry away heat produced by MOSFET, for better heat dissipation effects.
