Making a PC part 6: The Graphics Card + The PSU
I go over how I installed the Graphics Card
BUILDING A PC
The Power supply unit supplies power to all your components, and without it your PC wouldn't work. It connects all your components and wires.
If you're going to go all out and spend a lot of money on anything, the GPU (or CPU) is what you wanna spend most of it on. With a high end graphics card, you get amazing graphics, and faster loading time for what would otherwise be an incredibly slow program.
