I need some feedback on power supplies. Gateway has sent me 2 power
supplies 6500703, but the power supply in my system is 6500583. They say
it will work but when I talk to the tech support people that say I
really do need the 6500583. I had a lot of work done on it at the
Country Store to get is the way I want it and that is why the Country
Store said it was a good thing that I got that power supply because of
what I have configured in my system.

Here is what I found is the difference on GW support site.

6500583 H - Auxiliary Power Connector

The six-pin connector on the left is the motherboard auxiliary power
connector. This auxiliary power connector accepts a power lead from the
power supply. This auxiliary power connector supplies additional current
for the front panel USB and is required for proper operation of the
motherboard.

The motherboard has more than one power connector because federal
regulation allows a set level of current through each wire. If more
current is needed, more terminals are required, hence this auxiliary
power connector.

Note: When reseating any components or working inside the case, unplug
the power cord and wait for the green light to turn off (10 seconds
maximum). There is more available current supplied to this motherboard
than others. Failure to unplug the power cord will cause shorts and hot
spots on the motherboard and the component you were working with.

6500703 B - Auxiliary ATX Power

This is a closer view of the ATX auxiliary power on the motherboard.
This 2 × 2 power connector accepts a power lead from the power supply.
This auxiliary power connector supplies additional 12-volt service for
the processor and is required for proper operation of the motherboard.
The clip on the ATX power connector faces toward the front of the
motherboard.
