Du skal have en større strømforsyning. Asus siger selv at den skal ha' mindst en 400 watt forsyning. har selv haft problemet. jeg har selv skiftet min 355 watt ud med en på 466watt. Jeg fandt dette på ASUS's hjemmeside:
ATX Form-factor and Minimum 400W ATX 2.03 Power Supply
The minimum requirement for full-power loading is a 400 Watt ATX 12V power supply; minimum requirement for +5V/3.3V is 180 Watts; +12 Volts requires 15 Amps; 5VSB requires 1 Amp. Also Ensure that the ATX power supply can put out at least 10mA on the +5 Volt standby lead (+5vsb). You may experience difficuly powering ON the system if the power supply cannot support the load. For Wake-On-LAN support, your ATX power supply must supply at least 720mA for +5VSB.
