PSU Problems

[euphora]

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.

Have you hooked up the graphics card power connector to the PSU?

 

[euphora]

There's no pins on the graphics card I've checked

Did you disable the onboard graphics in the BIOS and set video to PCIe.

Not much of a PSU 'upgrade.'

 

[euphora]

The bios is setup for pci-e first

I suspect your new psu is faulty.


I would return it and buy a known good quality brand such as Seasonic, XFX, Corsair, Antec, or PC P&C.
Here is one tiered psu list for reference:
