    Solved Issue with OCZ OCZ600SXS ATX PSU with very low voltages

    This OCZ OCZ600SXS 600Watt power supply came in supposedly working after I loaned out a power supply for a potentially faulty one that I had supplied with a PC.
    Anyway needles to say I thought this was a result as the original one loaned was a 460Watt HP unit. However when checked all the 12V 5V and 3.3V voltages were all low around half of what they should be.
    Anyway after investigating I identified a couple of 2200uf 6.3V Capxon capacitors failed and a 100uf 25V Capxon failed as well. The main culprit was the 100uf 25V which was over the opto isolator.
    The 2200uf 6.3V were quickly changed however it took me ages to work out where the solder points were on the rear of the pcb for the 100uf 25V. So I have attached a few pictures to show you the location on the rear of the pcb.

    I am sure this will help someone out in the future locating the parts.

    Happy repairing
