The PSU is from Brand X, model Y, and the RAM is from Brand Z, model A.
When you power on the computer, do you notice the Motherboard Manufacturer's Splash Screen Logo? Or does the display remain dark? If a logo appears, press the Del key several times to access Setup (Bios) unless it's an HP system, in which case use F10. If the screen is black, attempt to detach the GPU and rely on the built-in HDMI integrated graphics.
No splash screen appears, but the motherboard connection is damaged, making it impossible to insert it. I recommend trying to unplug the GPU and then reconnect it.
