Question These voltages don't seem... right. Time for a replacement PSU?

[EdB 81001]

EDIT(S): (Thanks, Ralston, for the quick response.)

First, I felt really dumb after I opened the computer, couldn't find a power supply, per se, and then remembered it's got DC voltage coming in from a power brick that I had just unplugged from the back of it. Derp!

I tested the DC end of the 90-watt, 19.5V, 4.62A, power brick cable and it registered just over 19 volts.

Everything inside this Inspiron 24 5459 AIO is from the factory, except for the DVD-RW drive I swapped out this morning while I had it apart because the original didn't want to burn anything (the replacement works just fine). It has 8G and 4G DIMMS for 12G total, and a 1TB HDD. Processor is Intel(R) Core(TM) i5-6400T CPU @ 2.20GHz, onboard graphics. I think it rated a 12% on gaming goodness, LOL.

It was driven by my little-old-lady sister to read emails, check Facebook, and maybe play Candy Crush every once in a while.

Here are the voltages after I put it back together, from HWMonitor again, as there is no voltage reporting feature in the BIOS.

Thanks again for taking a moment for me. The thing that started this -- the (CPU, I found out) fan running loudly -- has settled back to what I consider normal, but these voltages still freak me out a bit.

ORIGINAL:

I recently inherited an older Dell All-in-one computer that's way faster than anything I'd been trudging along with previously. This morning I heard the fan wailing away after a night of doing nothing (as far as I know) and wanted to check the temps. They look fine, honestly, but then I noticed the voltage readings. Should I turn this baby off till I can find a new power supply? I'm worried, LOL.

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)? History of heavy gaming use, video editing, or even bit-mining?

Disk drives: make, model, capacity, how full?

Do you have a multi-meter and know how to use it? Or know someone who does?

FYI:

Any PSU voltages out of tolerance would be of concern.

Do you have all important data backed up away from the system in question? And the backups are proven to be recoverable and readable?

If not, then do so.

I don't think, that software is reading voltages right.
Check voltages in BIOS or with multi-meter.

The voltage reading is wrong. If that would be the real voltages of the PSU the system should never start.
