I had a look and it was very close, I noticed there are two red lines in the in the first +5vdc on and two orange cables going into the second +3.3vdc on the side without the clamp.
Thank you again for the help.
It is a standard IEC connector.
The issue is kind of opposite, the power supply is good, I am putting in a new mother board, and do not want to pay for a new power supply on top if it if I can at all avoid it.
You can get a power supply tester which checks the voltages on 20/24 pin motherboard connector, ATX 4/8 12V, PCIe 12V (graphics card connectors)
molex, floppy and SATA connectors which will give a good indication of compatibility.
also look for any non standard connectors not mentioned above.
