Q: What's the power supply on this?
A: undefined
A: The version I purchased came with a 2TB rotating drive. I did a Norton Ghost backup and tried to restore the image to a 1TB SSD purchased separately. But Dell's image contained "unmovable" files just past the 1TB location on the original drive. In the end, I installed the 1TB SATA SSD then installed Windows 10 from a bootable DVD downloaded from the Microsoft web site. It didn't work the first time, but did work on the second try. I don't know why. I'm now running just fine with only the SSD. So, possible with some work.
