[Build Help] Trying to find the right AC adapter for an MSI-7481 motherboard

I'm not sure if this is the best reddit for this, but I'm trying to find an AC adapter that will work with an older PC I got my hands on.

It's this model, I'm just missing the AC. It doesn't have an internal psu, and instead takes a cable and adapter like a laptop.

Here are my clues:

From the Specs page:

65 Watt Power Adapter with Active PFC

Printed on a sticker on the back:

19V,3.42A

I'm planning on using it as a basic htpc with XBMCbuntu, just needs some juice.

Update: I tried it with my Antec universal laptop adapter. The power brick says 19V 4.74A. Nothing happened. Is it broken? Or will those power specs not work?

Update2: u/hiding_from_my_gf made me feel like a complete idiot and found the adapter.

Update3: I made me feel like an even bigger idiot, when I found that the former owner had dislodged the cable for the power button - universal laptop charger will work until I buy the above adapter.

Nothing to see here folks, I'll be on my way.
