I recently replaced my old power supply (VX750) with a new one (CX750). After turning on the computer, it powers up fine, but the screen is displaying 'no signal'. I checked the HDMI cable and monitor by connecting them to my laptop, and they worked perfectly. So, I'm not sure what's going wrong with the PC setup.

Did you connect it to the graphics card or did you try the motherboard? Just a thought, but sometimes if you connect it wrong, it can cause that 'no signal' issue.
Make sure the new PSU is properly connected to the video card. Sometimes, it can get a bit loose when you install it. Check that it's snug and secure! Also, it might be worth verifying if your video card was accidentally unseated during the PSU swap.
Have you tried changing the input on your monitor? It could be set to the wrong source, which would explain the 'no signal'. Just a quick check that might save you some hassle!
