This motherboard is with switching regulator onboard that supports CPU over-current protection, and it applies to 3. 3V/5V/12V power supply for providing full line over-current protection. 5V (Protected by power supply) ATX Switching Power Supply 3. 3V (Protected by power supply) 12V (Protected by power supply) Onboard Power Regulator Over-Current Protection Circuit CPU Core Voltage Note: Although we have implemented protection circuit try to prevent any human operating mistake, there is still certain risk that CPU, memory, HDD, add-on cards installed on this motherboard may be damaged because of component failure, human operating error or unknown nature reason. AOpen cannot guaranty the protection circuit will always work perfectly. 52 MX4LS H a r d w a r e M o ni t o r i n g Online Manual This motherboard implements a hardware monitoring system. As you turn on your system, this smart design will continue to monitor your system's working voltage, fan status and CPU temperature. If any of these systems' status goes wrong, there will be an alarm through the chassis external speaker or buzzer of motherboard (if existed) to warn the user.

Resettable Fuse 54 MX4LS 3 3 0 0 F L o w E S R C a p a c i t or Online Manual The quality of low ESR capacitor (Low Equivalent Series Resistance) during high frequency operation is very important for the stability of CPU power. The idea of where to put these capacitors is another know-how that requires experience and detail calculation. Not only that, MX4LS implements 3300F capacitors, which is much larger than normal capacitor (1000 and 1500F) and it provides better stability for CPU power. 55 MX4LS E nl a r g e d Al u m i n u m H e a t s i n k Online Manual Cool down CPU and Chipset is important for system reliability. Enlarged aluminum heat sink provides better heat consumption especially when you are trying to over clocking the CPU. 56 MX4LS O p e n J u ke B o x P l ay er Online Manual Here we are pleased to provide you a brand-new powerful interface--Open JukeBox.
