    Intel i3 7100
    Motherboard: msi b250m pro-vdh
    2 x 8gb crucial ddr4 2133mhz
    500w Tesla psu
    Windows 10 pro on 120gb wd ssd
    1tb wd hdd
    Graphics card: Asus Radeon 7770 2gb

    This is the first computer I have built, and it works completely fine without the graphics card. The card was given to me by my brother in law a few days after I built it, it’s new but has been sat boxed in his house for over a year. Anyway when I install the card, my pc fails to boot and I get a vga light on the ez debug on the motherboard, doesn’t even get to the bios.
    I have updated the bios, I’ve ensured it is fully seated in the pcie slot, I’ve tried with just one stick ram in slot one, I have installed the drivers for it.
    Also if it makes a difference I’m using a 2 x4 pin molex to 6 pin pcie adapter, but I’ve been told my psu should be capable for this setup?
    Any help on this would much appreciated, thanks

    First Name:
    A "Tesla" brand PSU is not a high quality unit.

    Secondly, the MINIMUM wattage for your card is listed as 500W.

    So your power supply is most likely not strong enough to support that card.

    I would install a larger, HIGHER QUALITY power supply and then see if the issue persists. Something like a Corsair RMx 850.
