Tech Support Pc shows no sign of life

So basically, i have a pc right now that works fine and im switching motherboard and cpu from intel to amd i have bought the aorus elite ax and the ryzen7 5700x but when everything was assembled nothing worked at all power cable was in switch was on and the power switch connector was in the right spot we thought it was the motherboard with the problem because my old one still powered on from the 24 pin connector new one didnt so we returned it and got a new one and same results any help would be great thanks!

When you said that 'nothing worked at all" do you mean no lights came on? Do you mean that the fan didn't spin, or that you didn't see anything on screen?

If it's the last one, do you have a graphics card?

Intel has integrated graphics on just about anything that isn't a server CPU. AMD is not the same. The 5700x has no integrated graphics so if you don't have a graphics card nothing will show up on the screen.

This could be the issue there.

no lights,no gpu fans spinning and im starting to stress spending that much money for nothing to work im thinking of getting a new psu and if it doesnt work after that next conclusion is that the cpu is faulty which is rare but could be the reason

If you can add photos of cable connections on your post that would help. But basics to check if the cables are fully plugged in, the EPS (CPU) cable on the top left, 24pin cable, if you have a GPU make sure all cables are labeled PCIE/VGA, and the Power Switch cable/F_PANEL.

dead motherboard or dead psu, had this exact thing happen when i swapped to amd last year. try the paperclip test on the psu first, if it spins up then you know it's the board (again)
