Swapped your Corsair VS450 for the TX650M, connected it to your PC, and everything is working—fans are spinning and LEDs are on. But your keyboard won’t light up and the monitor shows “No signal.” You cleaned RAM, replaced GPU, and confirmed all connections are secure. What could be causing this issue?

I'm testing it now; my motherboard has a bright white light and beside it is written "cpu" in tiny letters. This might be the problem.

Completed the task, but performance remains subpar.

The instructions indicate the system isn’t detecting the CPU. Besides replacing the power supply unit, have you performed any additional checks or adjustments?

You replaced the power supply, the CPU cable is connected, and the CPU cooler is running.

The CPU cooler starts spinning when the motherboard receives power, as it picks up its signal. Did you connect the 4+4 cable correctly?

The wire connects to the processor, marked with "cpu" on one side, and features four slots at both the top and bottom.
