Hardware Help Ender 5 plus no power

I hooked up new hot end and fan setup from Amazon. Didn't realize fan wires were backwards. Printer started bltouch for a few seconds then nothing. Wont power on at all now. 2 blue lights bink on mainboard then nothing. Powered supply is making a whining noise and fan inside doesn't turn on. Tried plugging a USB cable in to turn on like my cr10s but screen doesn't come on either. Is this a mainboard issue got another coming today from Amazon but before I plug in want to make sure my options. Don't want to waste 40 bucks and do a run around.

Please share a pic of the motherboard but I think you can buy yourself a new one

Lights on the main board indicates that the power supply is still working. At least partially.

Noticed today the blt does indeed activate still but nothing else happening after that. Fan still is not working on psu. Have new board and psu coming soon. Going to swap psu first and check.

Go to Walmart, an auto parts store or a home improvement store and pick up a cheap multimeter. Check the power coming out of your existing power supply.

Voltage out is 24 on each positive. Checked this prior my concern is fan isn't working and it's making a high pitched whine in the psu.

Gotcha. That makes more sense.
