    This is the first time I've built a computer and it doesn't seem to be POSTing.

    The mother board is ASUS P8Z680-V and the CPU is an i5 2500k. All cables are plugged in, including the ATX/CpU 8 pin power cable.

    What happens is the motherboard powers up for a good 10 seconds, I get no beeping from the speaker, then it powers down, then it powers back up again and stays powered on until I turn it off, I get no display on the monitor or no beeps on the mobo speaker.

    When it powers off after 10 seconds the CPU led lights up for a split second. The DRAM light is on though. I've tried different combinations of RAM and nothing seems to work. I've tried taking the RAM out just to test if the speaker is working and it was, I was getting 1 long beep followed by 2 short which indicates memory problems.

    Please post your system specs, To include Make and model Ram, Video Card, Hdd(s), Optical Drive(s), Power Supply Manufacturer Model, Wattage and Amperage on the +12V Rails, OS, and any other peripherals installed on the motherboard.

    You have already provided the Mobo and CPU. The rest is also needed.

    Have you tried the system with just one of the Video cards installed? Silverstone is not really a quality brand Power supply and may not be providing its advertised Wattage and amperage.

    Really? It has some silver standard award? Perhaps that means nothing.

    All computer component manufacturers have their up's and down's. I don't know what Silverstone is currently marketing, but I do know that previously their power supply's were good.

    Just from my personal experiences as an OEM builder/repairer the 4 things I look for in a power supply for high performance applications are these.

    #1-Single +12v rail.
    #2-Power output calculated at 40-50°C.
    #3-Non-modular, hard wired cabling.
    #4-5 year or longer warranty.

    Silverstone pw supplies are fine; on par with corsair or seasonic.

    Next have you read and followed the guide at the top of the page for problem builds?

    I stand corrected, The limited experiences I have had with them were older models and for me were not positive.
