XPS M140 Notebook Power Supply Usage

I just bought a new PA-10 adapter on eBay and the listing said it was compatible with the M140.  Well like an idiot I didn't look on mine to see that it said PA-12.

 

So my question is, will the PA-10 work with the M140 with no problems?  The only difference I can see is the wattage.  The PA-12 is a 65 watt and the new PA-10 is a 90 watt.  Output voltage is exactly the same and the connector looks to be the same.

 

It was brand new in the package and with shipping was less than $9 so I thought I would take a chance with it but I don't want to trash my computer.  I haven't complained to the seller yet and wasn't going to until I had done my due diligence and checked the forums.

 

Thanks.
