Need help, Recovering data from an IDE hard drive and transfer to another drive

As title says. I need help Recovering data from an IDE hard drive and transfer to another drive.

My mid tower Dell power supply went out so I need to recover the data from the IDE hard drive and transfer it all to an 500gig external hard drive. 

I also have a sata 200gig laptop hard drive that I need the data from and planning to use it in my Dell 6400 laptop.

I bought this kit from ebay an arrived few days ago.  USB To IDE SATA S-SATA Converter Cable Cord Adaptor. 

Appreciate the expertise, from the wise Dell people in the community.
