PSU 6-pin Aux not needed, convert to 4-pin possible?

What do you need the 4-pin for?

I don't think so. I rummaged around in my junk box and found an old ATX 1.3 PSU. The connector you are talking about looks like half of an old AT PSU (flat white connector that looks like it mates with flat pins, right?

The 6 pins are:
3 black - ground
2 orange - 3.3 volts
1 red - 5 volts.

12 volt output is not available. If you need to run another drive, buy a Y-type drive power adapter (molex female to 2 molex males).

Jsc, That is the connector I am talking about. There are a few other 6-pin threads on here about newer power supplies and older motherboards but I have the opposite situation.
Thank you.

I still have two 4 pin molex available. I'm using a full tower case and I believe the power supply is a decent one. I didn't want to overload it with drives and fans though.
