Yes Qatar has 220v. But dont worry, I suggest you buy a separate Power Supply for your PS3 which would likely be 110v if you're taking the US version PS3. Power Supplies are like boxes, like the ones you see under computers.

Computers need a separate Power Supply. They both got 220v and 110v. Make sure its 110v if you're going to plug it in 110v, DONT plug the US version ps3 in 220v, or else you'll get a brand new 500$ Paper Weight.
