    Question Newly build PC from PCPER tutorial no POST

    I was following this tutorial by PCPER.
    I bought all the parts needed. I followed the tutorial exactly. Triple check everything.

    After the tutorial I run the newly build PC and got nothing.. No display, it cant detect keyboard, no beep sound, GPU fans not turning ON only CPU fans

    My CPU is

    AMD FX 6300 6-core black edition 3.5GHz AM3+



    Motherboard is
    MSI 970A-G43 AM3+


    HDD is
    Seagate Barracuda HDD Internal Bare Drive 1TB 720 RPM



    I dont have an SSD



    PSU is
    Corsair CX Series 600 Watt ATX/EPS Modular 80 PLUS Bronze ATX12V/EPS12V 552 Power Supply CX600M


    GPU is
    Gigabyte Radeon R9 270x 4096MB GDDR5 OC version

    RAM is
    Corsair 8G DDR3 1600MHz vengeance low profile

    Here is my build image




    In here you can see that i move the GPU to another slot and so as the RAM. you can see that CPU fans are working except the GPU fans



    Any idea whats is the problem?

    GPU is becoming warm if I left it runnig for 5mins or so yet its fans isnt running.

    Please help

    Make sure you haven't got pci-express cable(s) mixed up with motherboard power cable.
    I have done this in the past and know of 2 others also made same mistake. Pci-e cable can be wrongly plugged into motherboard.
    Result is no boot situation.

    Check it again and I am sure that PCI-E cable is plugged on GPU
    In the GPU. there is a 6x2 pins


    This is the pin that i connect to the picture above


    At the end of the cable is an 8pin


    This is where i connect the 8 pin in the PSU.(top of the 8pin socket with the RED mark )


    is it a problem if the GPU is PCIe 3.0 and MOBO is only 2 PCIe 2.0 x16 slots?

    No. Im pretty sure the cable is connected to GPU not on MOBO

    Connection of GPU and its cable


    at the end of this cable is an 8 pin that should be connected to PSU. This 6x2 pin socket is connected on the picture above


    GPU connected to PSU using 8pin socket


    Here is the 8 pin socket that will be connected on PSU -- green mark


    Could this be that GPU is is PCI-E 3.0 and MOBO is only 2 PCIe 2.0 x16 slots?

    NO. Im pretty sure about that. I connect the PCI-E cable on GPU
    Here is the 6x2 pin socket of GPU


    Here is the 6x2 pin cable for GPU


    Here is the connection for PSU -- 8pin


    that will be connected to PSU (mark with green arrow)

    I would make sure that the gpu is fully seated in the slot, put your memory in the first slot closest to the cpu. Use the two black slots if using two sticks.

    I looked at the manual and this board uses only 6 mounting screws to the chassis.
    2 in the middle line of the board from your photographs look like they are missing ?? In your first picture of your post they are viewable just above the video card top edge on the left and right side, and in the second picture on the bottom left of the left ram stick and one near the left chassis side by the upper slot chassis bracket.Hard to see very well but I don't see any screws.
    Maybe it's just the light, but anyway make sure that you don't have any extra standoffs under the board that don't match up to mounting holes on the board, and make sure the board is mounted correctly. If there are no mounts in the center it could be flexing and get damaged.
    Maybe I'm just not seeing it very well in your pics.

    okay.. I double check everything again. tried using an older GPU and its fan works. However still no POST

    I realize I have a missing pin on my CPU. Will this be the culprit?

    More than likely.I don't see a pinout to know what function that pin has.Maybe if it's just a duplicate ground it would not matter, but in all likelihood it has a function. There is also a badly bent pin above that pin about 5 pins away.
    The only way to know is to try another cpu.
