New ATX Power Supply on old Motherboard

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
I have roughly 3/4 year old PIII Gateway PC with a standard Power
supply (ATX).
I recently got myself a new silent power supply for this PC but the
motherboards power signal connector is different on this Power supply
to what I have on my original power supply.
My current power supply has the standard 3 pin type connector that goes
on the motherboard but the new Power supply has a square 4 pin type.

So my questions are:
Have I explained my self well or I need to give more details?
Have I bought wrong Power Supply?
Is there a way around this - like getting an adaptor or something?

Any feedback greatly appreciated.

I think you use the term "power signal connector" loosely.

The only connections you need are the 20 pin main
motherboard connector, for a "common" Gateway PC.  You don't
need the 3 pin fan control connector for proper operation of
the system.

All newer ATX 2.03 PSU have it, but you don't need it on
your system.  Take a nylon wire-tie and curl that connector
+ wires up and strap it out of the way.

Hook the PSU up with the 20 pin connector, make sure all
wires are out of the way, and try the system.  Also make
sure that if there is a voltage switch on the rear of the
PSU, that it is set correctly for your location (110 vs 220
volt AC).
