How do i test this 14 pin power supply, ie what cables do i jumper and what do i use for ground. Thanks in advance

akshay patel, you connect PSON (pin 4) with +5VSB (pin 5) to turn it on. You do want to try this with a resistor across the pins first. This PSU may also require a load in order to stay on, so attach a drive or similar to it as well. Hope this helps, good luck.
