This is a classic tale of failing psu that once in a blue moon was still able to start the system but most of time causing a strange power button behavior. Beware it will fail completely one day soon to come. Time to get a replacement psu.
The service tag info is inside bios if the Dell sticker has gone lost on chassis.
System Information
Displays the following information:
System Information - Displays BIOS Version, Service Tag, Asset Tag, Ownership Tag, Ownership Date, Manufacture Date, and the Express Service Code
before you buy a replacement do you have a spare working 24/4 pin psu? you can use the spare psu plus a 24 to 8 pin adapter to test 9020 mobo and confirm stock psu is not good. If you want to jump ahead to get a replacement you have two options: buy genuine Dell psu on eBay, or buy standard form factor psu + the 24 to 8 pin adapter. Users who chose 2nd option did so because they wanted to upgrade to higher power psu for gpu support. otoh if you just want to keep the pc vanilla without mod then get the Dell psu (it has proprietary 8 pin white connector). New psu on eBay or open box on eBay.
