HP Recommended

I have a HP TP01-2234 desktop. I want to put in a 400 watt power supply. My 190 watt one has 4 wires to the switch connector on the motherboard. The 400 watt one I purchased has only 3. It is missing the one next to the black wire. All the 400 watt supplies I have found have only the 3. I can add a 4th wire Hp part number 76557-001 model PA-3401-2HA. We're the wires are soldered to the board there is one marked bs with nothing on it. The 3 wires that are there are the right colors and in the right place.
