To meet expansion requirements, it is recommended that a power supply that can withstand
high power consumption be used (500W or greater). The main power connector is compatible
with power supplies with 2x10 power connectors. To prevent system instability or system's
failure to boot, be sure to connect a power supply providing a 2x12 power connector.
