Under the Hood
Here are a few pictures showing the layout and components inside the Ultra X3 600W power supply.  The internal circuit board and components are nearly identical to the Ultra X-Pro EE 600W unit, which we reviewed earlier this year and earned a PCPerspective Editor’s Choice Award.

The top view is dominated by the large heatsinks and just like the other Ultra power supplies we have reviewed previously, the X3 600W modular power supply appears to be manufactured by Andyson International Co LTD. All of the Andyson built Ultra PSUs have performed very well, so we have high expectations for this new X3 modular model.  The overall layout appears to be very good and all of the Teapo branded capacitors are rated for 105°C.
