Powering 3D scanner with PC power supply

I have Einstar 3d scanner and i am building mini portable PC case so that i can scan outside the shop without carrying big components.

I had an idea to integrate the power plug for the scanner in the pc from the power supply (PC psu is thermallake smart rgb 700w). The psu have extra 12v wiring.

So is it safe to power the scanner from the pc psu without damaging it? And will it work properly?

3d scanner psu output is 12v 60w.
