  1. Yesterday my power supply was blown up (fuse). So i bought the power supply (PS HEC 300W) and plug in my compter which is assembly with Intel Desktop Board D845GEBV2 mounted with Celeron 2.0GHz. If i am not wrong, it is compatible with my mother board right. But there is problem after switch it on the power. First i switch on the main switch in the power supply. And i realised that the CPU fan is running although i didn't switch on the power from the front panel of my system unit. The LED for the harddisk in the front pannel also light up even though i didn't connect power to the hard disk. Is it the Mainboard problem. :mad:

    Hello! Welcome to TechSpot

    I see from pic on intel your board has two power plugs,
    did you plug in the 4 pin plug as well as the 20 pin?

    Power Supply and mother board problem

    Yes SOcRatEs. I did plug in both 4 pin socket and 20 pin socket. in the HEC 300W power supply, there are
    ATX main connector (20 pin)
    ATX power connector (6 pin)
    6 x Peripheral connectors
    2 x FDD connectors (4 pin)
    1 x +12V power connector (4 pin).

    I plugged in ATX main connector (20 pin) near to the IDE slot and 1 x +12V power connector (4 pin) near to the CPU. I tested without plug in 1 x +12V power connector (4 pin) but still the same problem happen.

    Thanks
