Just got the Pironman 5. Installed a 4tb NVME. Model was on the compatible list and I can mount it just fine. I have nothing connected. no keyboard or mouse.

I am using a 165watt power supply with a 240watt cord. The same items I use to charge my HP laptop with no power issues.

I keep getting low voltage. Not sure what else to do.

Please provide us with the complete specifications of your power supply. A higher wattage power supply is not necessarily better; the key is whether it supports a 5V, 5A output.

We recommend using the official 27W power adapter for the Pi5 or a third-party 5V, 5A power supply to power the case.

Yep I would have never thought it.

Both only put out 3A at 5v.  
Looks like I will be ordering a different power supply

Correct. A power supply with 5V 5A output is needed to meet the power supply requirements of the Pironman 5 case.
