I bought a PowerSpec G445 (link below) and I wanted to know if I can upgrade the graphic card to a 4090. Would it fit the case? I am new on this so not sure if this is even an option. Any advise will be breatly appreciated.

    The case your PowerSpec is in lengthwise supports up to 13.7" video cards, so some, but not all 4090 models will fit, you'll want to double-check the length of the specific 4090 model card you're looking to get.

    The second thing I'm seeing here is that the PC you have only has a 750W power supply and 4090s will recommend a 1000W power supply so you will need to upgrade to that wattage of supply. Hopefully this helps!
