I’ve tried everything, plugging and unplugging, holding the power button, resetting the SMC, EVERYTHING
it still won’t turn on, all the lights around the ports turn on but not the power button itself, and nothing happens when I press the power button, HELP PLEASE :(

Original Title: My Trashcan Mac Pro will not turn on
Mac Pro, macOS 12.7
has your Mac Pro late 2013 model recently been off power? such as being moved form one outlet to another, or disconnected or stored for a while?
Your Mac contains an always-on power supply, used to maintain parameters and also provide power for the power-up logic. if it has been off power, the PRAM backup battery may have been forced into service, and can eventually be run below the 3.00 Volts and become ineffective at keeping corruption out of the parameter RAM.
The "fix" for OTHER desktop Macs is to replace the readily-accessible 3 volt non-recharging coin cell battery.
BUT: On your model Mac Pro, it requires a 32-step teardown to measure or replace that battery. A readily available CR2032 (used in garage door opener control and car-key fobs) can be substituted for the factory BR2032.
You have a decision to make.
if you wish to continue to use this Mac, the 32 step tear down and replacing the battery also refreshes the connections between the processor card, the graphics cards, and the power supply. it is not difficult, but is complicated. The procedure can be found with a modest web search.
Posting the notorious web site will get this posting removed, because it needs to be accompanied by warnings that following that procedure might damage your computer or your person, and should only be attempted by experienced technicians.

UPDATE: my Mac has been repaired, apparently they just removed a stick of ram and put it back in, I also tried that, but it didn’t work??? Whatever, as long as my Mac is back!!!
If the general troubleshooting mentioned in this article did not work, you will have to get your Mac Pro serviced:
If your Mac doesn't turn on - Apple Support
You can use this online link as a start:
if you are confirming that the backup battery may be dead, you have decision to make.
Your choices are:
• discard this Mac.
• find the procedure, obtain the written instructions, and either perform the tear down and battery replacement, or pay a technician to do it for you.
I’m pretty sure it’s because of the powercuts that happen a lot where I’m from, what do I do?
If power outages, did you consider buying an Uninterruptible Power Supply (UPS) unit?
