    PSU is too small, the 770 requires a MINIMUM 575 W PSU, one with a 6 pin and a 8 pin PCE video power connector (both of them)

    That means you should have a bit more than that, a 600W to 650W PSU. Your 450W just is not good enough for that video card.

    No mention of RAM, but will *assume* that you have at least one stick installed.

    My guess would be your power supply.....MSI says that to use their GTX 770 (which can pull 230W) you'll need to use at least a 600W power supply.

    Same here-

    Minimum 575W here-

    possible -- monitor is looking for input on the wrong type of connection. use the monitor's manual buttons to change to correct type of input being supplied

    I've built a new pc using a Gigabyte 990x Mobo (G-990x for short). (The mobo doesn't have it's own integrated graphics by the way so a graphics card is a must install).

    All components are compatible, I checked. My MSI 770 Graphics Card has been tested on other PCs and it works fully. My Monitor and cables work fully too. I have also tested another Graphics Card on my G-990x. However, I still have no display even though the fans spins. Any idea how to fix this?

    I can't even get into bios. Like nothing shows up on the screen. Normally if there's something wrong, there should be a beep sound from the motherboard but even that doesn't happen. I once deliberately took out the CPU to check but nothing. There is no beep sound at all.

    The full specs are:


    Mobo (New): Gigabyte 990x Gaming SLI.

    CPU (Used Condition): AMD FX-6300.

    Graphics Card: MSI 770.

    CPU Fan (New): Stock AMD Cooler.

    PSU (New): Corsair VS450.

    HDD (Used Condition): Seagate 750GB.

    SSD (Used Condition): Samsung Evo 256 GB.

    ATX Case: Sharkoon VG4-W.


    Please help me with this as soon as you can. Thanks.
