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.

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

Not much of a PSU 'upgrade.'

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:
