How to verify power provided to processors is clean
The DRAC is your friend usually the logs are obvious. If you still have warranty open a Dell Chat, ask for the DSET link, run it, and tell them to ship you parts. The diagnostic process will be:
- Complain to Dell, run a DSET (Diag tool), have them ship you parts
- Replace parts
- If !satisfied go to step 1, else continue
- Be happy.
Don't waste your effort thinking it through. It's Dell's dime. Just change and complain. It's not like the parts take long to change. You will eventually get it right (as well as a ton of new parts). If you're too lazy to do it pick up a contractor on Amazon Mechanical Turk for $3/hour to do it for you.
Dell is very nice. If you feel it is the PSU tell them that and they will usually ship you one of those. You can always say it sparked, arced, or smoked and that's a guaranteed PSU replacement
