    I recently purchased components for a new gaming PC. I installed the components out of case, to test whether it all works. After installing and providing power to the CPU, GPU and RAM, the PC would not turn on at all (almost like there is no power). I have tested the PSU and it works. Not sure if the motherboard is Dead, as there is no lights once its all plugged in.

    Is there any way I can test just the board?
    What else could be the problem?


    • AMD Ryzen 7 1800X Octa-Core 3.6GHz (4.0GHz Turbo) Socket AM4 Desktop CPU
    • Reeven RW-2401 NAIA 240mm RGB Closed Loop Black Liquid CPU Cooler
    • MSI B450 TOMAHAWK AMD B450 Ryzen Socket AM4 ATX Desktop Motherboard
    • Super Flower SF-650F14MT(BK) Leadex 650W 80 Plus Silver Certified Fully Modular Black Desktop Power Supply

    Any help would be appreciated

    As a starter the prime culprits are
    Main power connection not correctly made by that I mean the 24 pin is not properly seated
    CPU power not correctly made
    Modular power supply - lead to incorrect port on PSU
    Incorrectly seated CPU or even worse bent pin on mounting it
    Those are your starting points

    in that order
    After that see here

    How exactly did you test the pw supply? If you used the paperclip method, that is next to useless and does not test individual rails nor does it put the unit under a load. A pw supply test is slightly better however the best test is to install the unit in a bench system for testing.
    How exactly did you pw on the board? Did you short the pw switch pins or what?
