PSU Problems Tags: Power Supplies Components Last response: September 15, 2012 4:05 PM in Components Share euphora September 15, 2012 10:03:58 AM OK Heres it in a basic form Old PSU 250WATTS + HD5450 GCard = Everything works ok i can use the card no problems. New PSU 500WATTS + HD5450 GCard = Nothing on screen but the system starts up, have to plug into the onboard Gcard to get a screen. With the New PSU the HD5450 dosnt show up in the divice list. According to CPUID all the Volts are correct. I have reset CMOS/BIOS and have looked through the bios to check if theres a power option but nish. *Could the power supply be faulty *Could the Mobo be unable to take the new PSU *Am i missing something The system is on a MRS600M Mobo But according to the mobo itself it has MS7326 printed on it. Its a ACER stock mobo. The strange thing is the 250watt psu should be able to run the system but it dose. The new psu is a High Power Plus 500 model.
