    Hi Guys - newbie here, hope you can help out.

    The PSU failed on my system after about 18 months, I went to the shop where I had the PC built with the dead PSU (Touchmate 400W) in hand and asked for a replacement.

    When I came to install the new PSU I found only 3 molex connectors instead of the original 5 and I had no splitters to hand. Leaving the DVD/RW drive unpowered the system booted up and ran normally.
    Following day I removed the PSU and took it back to get a different model. Now the problems begin! I get a new PSU, very handsome with black case and nice wiring looms and big fan, and install it. Press start button - nothing happens! The PSU and CPU fans kick and rotate briefly before stoppng. There is a green LED on the motherboard only. Tried reseating all connectors, boards, PCI connectors etc but to no avail. Tried powering MB/HDD only - same result. I then tried a cheap generic Chinese PSU (I know these are unreliable but this is just to check whether the PSU was DOA). Hey presto - system boots up normally. 5 minutes later however, this PSU dies!

    Went away to stand in a corner for a while:(

    When I came back - ever hopeful, I hit the power button again and was treated to a firework display from the PSU:eek:

    Now - concerned about the rest of the system I replaced the No 2 PSU which still acted the same.

    Questions...
    1. WTF is happening?
    2. Do I get a quality PSU (difficult to find in my part of the world - UAE) and risk frying that or do I take the whole caboodle back the the shop and risk paying for new components that I don't need?
    3. Or maybe the PSU is just shut down and can be revived?

    Sorry it's a long post but I have tried to explain fully
    Thanks in advance.

    System: P4 3.0GHz/Intel D915 MB/NVidia 6800GT GPU/Usual bits and pieces.
