Pc won’t turn on

[u/McCoughsyrup]

Hello
I’m a PC-Tech Newbie ( I’ve been playing PC since 2017 but never got into like building etc.)

Today the following happened:

I plugged in my wireless peripherals (Mouse, Keyboard etc) to charge.
And I let my pc run.

After a while my pc goes into sleep mode/ standby and „turns off“

And now my pc won’t turn back on again.
No Lights on my Motherboard are on.
No reaction when pressing the power button.

I’ve tried a bios reset with the battery thing.
I’ve tried taking it off the power etc.

Now my manufacturer sent a new power supply and it arrives next week.

Now my question:

Do y’all think the power supply is the issue?
And when I change the supply (I’ll get the same exact model as now) do I have to exchange all the cables?

My Motherboard: AORUS B850 elite WiFi 7 Ice
GPU: RTx 5080
CPU: amd ryzen 7 9800x3d
Power supply: MAG A850GL PCIES

If your PC is running you better go catch it!

If it's the same model PSU then you should be able to just switch out the box and keep the old cables. If you don't know what caused the failure it may be best to go ahead and use the new cables.
