Which fan is grinding? the fan in the PSU unit or the CPU fan etc? I had a power supply once that made all the DC fans buzz because there was an issue with the DC bridge in the power supply creating a 60hz hum. If the previous power supply wasnt bad, switch back and see if this new PSU has a bad DC bridge filter causing a 60hz rippled DC output.

Can you return or exchange the power supply?

From the other thread:

Your Computer:  http://support.dell.com/support/downloads/driverslist.aspx?c=us&cs=19&l=en&s=dhs&ServiceTag=&SystemID=DIM_PNT_9200_XPS_410&os=WW1&osl=en&catid=&impid=

Diagnostic Lights

If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might exist.

If the power light is steady amber, a device might be malfunctioning or incorrectly installed.

    Remove and then reinstall the memory modules (see Installing Memory).

    Remove and then reinstall any cards (see Cards).

    Remove and then reinstall the graphics card, if applicable (see Cards).

    Ensure that all power cables are securely connected to the system board. (see System Board Components).

What happened to the blinking yellow light?
Did you follow the procedure above?
It doesn't say anything about replacing a PSU.
