HP EliteDesk G1 i7 vPro with 19V 3.42A replacement adapter.

[Kris1986]

I recently purchased a second-hand refurbished HP EliteDesk G1 Business PC with i7 vPro,

The power adapter that came with it is a replacement and reads an output of 19V and 3.42A, but I have seen online that the official HP adapter that came out with most HP EliteDesk models listed an output of 19.5V and 3.33A, and the product sticker on the bottom of the computer, reads it requires an input of 19.5Vdc and 3.33A.

I know that the amperage being over should be ok, but have read that the voltages should match exactly. I have seen the device operating with the different replacement adapter, but am wondering if I use it over time could it damage the computer?

I also have found a 20V 3.25A adapter if this would function better in this scenario.

Technically you are right about the voltage but many models use 19v or 19.5v interchangeably. I would stay away from the 20v ....this is a small form factor desktop?

I believe so, it is basically a mini computer tower. So still using a 19V adapter should be ok, it won't be under-powered and take damage? They were using the 19V adapter (which reads replacement on it) so I figured it was ok, but like to double check.
