    I would look around. Newegg had it on their site when I pulled up your motherboard. The units with the cables that you plug into the supply may cost more. At least if the shipping is that cheap, you may want to get a good power supply that also protects your motherboard, since it is a better quality one.
    I just realized I gave the wrong mobo if that matters. I actually own

    GIGABYTE GA-H170M-DS3H s USB 3.0 Micro ATX Intel Motherboard - Newegg.com

    I'll look now for a good psu. It doesn't have to be modular, I was just curious if you had one on hand. Again, thanks for the link.

    I have three Intel Core 2 Duo systems in my Basement. The Power Supplies would never meet the demands of what you need. It at least gives you a chance to upgrade some items if they are on sale on newegg or amazon.

    The Corsair CX series PSU's have the cables that you plug into the unit, so that way you have a neat appearance for cables. Amazon.com:Corsair Memory Only

    I'll update when it's installed.

    Sounds like a faulty rail in your power supply unit.Either substitute a known working PSU or have yours tested.The test only takes 1 or 2 minutes.
    Please explain.

    Not trying to be argumentative, just seeking illumination.

    Good choice EVGA - I bought one of these after having two XFX PSUs fail under warranty.

    You can do a basic 'paper clip test' to check the operation of the PSU - see http://forum.corsair.com/v3/showthread.php?t=63991
    You could also check the output voltages to see if they are in spec. I would do this test and check the voltages on your new PSU before installation just to check the PSU is working.

    Also check that the connections from the PSU are secure - particularly the motherboard & GPU connections.

    The new PSU has built in self testing. The paper clip test could end up voiding the warranty, since it is not necessary for that test. All modular with only needing to plug in the power cables that he needs for what he has installed.

    The paper clip test 'simulates' connecting the PSU to a a motherboard to generate the handshake signal from the motherboard needed to turn on the PSU. How does the built in self test check that?

    You no longer need to do that with the newer power supplies. He is getting a brand new one in the box covered under a warranty. They just need to take out the old, put in the new, hook everything up and enjoy.

    That's what I plan on doing. If the new psu boots, old one is getting chucked.

    For bobkn.
    The psu delivers different voltage supplies for various fittings,e.g. one for an optical drive and one for a hdd.Each separate output is called a "rail" and any one can fail without the whole unit stopping .Hope this answers your query.if not let me know.
